Research activity


The ATLAS experiment is one of the experiments working on one of the four collision points of the proton proton collider LHC in Geneve. The LHC design energy is 14 TeV in the center of mass. Main targets of ATLAS in 2011/2012 has been the search and the discovery of the Higgs particle of the Standard Model. In hadron colliders lepton channels are the main tools of research thanks to the better signal/background ratio which allows a simpler identification of the interesting exclusive channels. LHC begun to work in stable conditions at the end of 2009, during 2010 and 2011 it worked at 7 TeV center of mass energy with rapidly increasing performance in terms of instantaneous luminosity. In 2012 the center of mass energy was increased to 8 TeV, to increase the production rate of interesting processes. In particular the Higgs boson production, being dominated by the gluon gluon channel, increased by about 25% for an Higgs of mass equal to 125 GeV.

The collected integrated luminosity has reached about 18 fb-1 at the end of October 2012.


Measurement of the muon inclusive differential production cross section


In the first year of my activity in ATLAS I worked on the study of the performance of muon reconstruction, working at the validation of the first W and Z candidate [MA1] and on the measurement of the inclusive muon cross section [MA2-3].

The last furnishes the differential production cross section of muons in pp interaction as a function of the muon transverse momentum in the range 4-100 GeV. The region pT < 20 GeV is dominated by the B and C meson decays, while the high pT region is dominated by the W and Z decays. Characteristic of the measurement in the high pT region has been to measure the cross section without isolation cuts on the muons, that suppresses the b and c quark contribution, and without further selection cuts dependent from peculiar production and decay mechanism of the signal (like missing Et in the W). This has allowed to reduce the systematics due to the theory uncertainties. The measurement has been compared with QCD model at the NLO + NLL accuracy, through the FONLL framework, and to MC predictions from Powheg+Pyrhia, Powheg+Herwig and Pythia. The accuracy of the measurement, at level of 10% in the main part of the range, has allowed to probe in particular the NLL resummation in QCD in the heavy quark production, being the data well compatible with NLO+NLL and in disagreement with the central value of pure NLO calculation. This has been possible thanks to the exploration of the high pT spectrum (pT > 30 GeV) where the deviation between the NLO+NLL and NLO calculation becomes larger. A deep discussion with theoretician has been part of this work, in order to obtain the needed theoretical predictions from the FONLL framework, that can be recognised in the acknowledgement to myself in the relevant paper (CERN-PH-TH-2011-227). The analysis has been published in Phys. Lett. B [P16], I was one of the editors of the paper inside the ATLAS collaboration and wrote the sections regarding the muons in particular [MA2]. My work concerned the study of all the aspects of the measurement, in particular the measurement of the trigger efficiency, the data driven background determination, the combination of all the ingredients to extract an unfolded cross section, the analysis of the data and the comparison with the theoretical models. The measurement has been presented in several conferences by the ATLAS collaboration in 2011, in particular it was presented in a poster at EPS2011 by myself, whose proceedings have been published in [Pr16], and presented by myself at the “Beyond the Standard Model: Results with the 7 TeV LHC Collision Data” [c20].


Higgs search and discovery in the WWlνlν channel.


Starting from the 2011 I worked in the search for the Higgs boson in the HWWlνlν channel. I gave contributions to the analysis in different fields. The analysis is based on the search for two isolated leptons and high missing ET from the undetected neutrinos. The search is performed in both the SF channel (where the two charged leptons have the same mass) and in the DF (where the two charged leptons have different masses). In the DF channel the main background are the non resonant WW production ppWWlνlν, the top pair production ppttbarW+W-bb while in the SF also the ppZ/γ*l+l- becomes important. The latter contaminates the signal region due to the tails of the missing ET resolution. In order to reject the top background and to separate regions with different S/B ratio (allowing to improve the analysis sensitivity), the data sample is divided in jet multiplicity bin, selecting jets with pT > 25 GeV.


The irreducible WW background is rejected applying cuts on the azimuthal angle of the lepton pair (Δϕll) and on the invariant mass of the lepton pair mll. In fact the spin 0 nature of the Higgs boson and the V-A structure of the weak interaction in the W decay favour small opening angle and so small Δϕll and mll. These variables will be called topological in the following.


At the beginning of 2011 I worked mainly in the event scanning of the interesting candidates to identify the source of observed excesses, in particular studying the lepton quality (in particular the muons) and the performances of the algorithm looking for jet from primary vertex (the so called Jet Vertex Fraction algorithm). Then I worked on the cut optimisation, in particular the definition of the MET cut and of the topological variables.


At middle of 2011 I started to look in particular at the normalisation of the WW background and the uncertainty related to its estimation. Being it an irreducible background its yield must be predicted from theory or extrapolated from control regions defined using the topological variables mainly affected by theoretical uncertainties. Therefore I worked in particular on the estimate of the theoretical uncertainty rising from a direct estimate of the background in jet bins and an extrapolation from jet binned control region. The definition of the background normalisation were primary linked to this study. For the low mass Higgs, an high mll (>80 GeV) control region is completely signal free and allows a safe normalisation of the WW background in for each jet multiplicty bin. This allows to reduce the uncertainty coming from the jet binning that are both purely theoretical (being the jet multiplicity largely affected by scale uncertainty) and experimental like the jet energy scale. At high mass, the signal shifts at higher value of mll (due to the higher mass and the higher momenta of the leptons) contaminating the background region, therefore an absolute normalisation of the WW yield is more appropriate in order to preserve an adequate signal acceptance.


The results of this study were also part of intensive discussion with the theory community inside the LHC Higgs Cross Section working group, and were reported in the second volume of the LHC Cross Section Working Group report [P17]. It has been published in the first large exclusion range of the Higgs boson from the ATALS experiment in the most interesting range allowed by the electroweak fit [P18, MA6] excluding the Higgs boson in the range 145 GeV < mH < 206 GeV at 95% C.L., where the low sensitivity at high mass is mainly due to the choice, in this paper, to use a similar normalisation strategy for the WW background at high mass and at low mass. The high mass approach were changed in the second relevant publication in this channel [P19, MA7] where the search was completed on the full 2011 collected dataset excluding an Higgs boson in the range 133 GeV < mH < 261 GeV. The WW was nrmalised using the MC yield thanks the proper evaluation of the theoretical error on the exclusive jet yield of the WW process. The expected exclusion for a SM Higgs boson was 127 GeV < mH < 233 GeV. The higher exclusion limit respect to the observed was due to an excess of events at 1σ level in the low mass region. These results were presented by myself at the ICHEP 2012 conference [c21].


During the 2012 I continued to work mainly on theoretical aspects related to the Higgs boson search inside the WW group, and followed closely the analysis to identify problems and help in providing solutions. I was editor of the internal note regarding theoretical uncertainties and aspects of the Higgs boson search from both the signal and the background prospective [MA4, MA5]. I evaluated the uncertainty related to the main background estimated from MC and correction factors like WW, Wγ and Wγ*. I became ATLAS contact for the Higgs cross section working group, responsible to provide solutions agreed by the ATLAS and CMS collaborations, in particular regarding the gluon gluon fusion subgroup. In particular we defined the prescription for the utilisation of the ggF cross sections using the Complex Pole Scheme for the Higgs width in the whole mass range, for the utilisation of the Higgs pT provided at NLO+NLL in the Powheg MC and the utilisation of the finite heavy quark correction in the gg loop.


In this period I was also MC responsible for the Higgs group, responsibility that consists in choosing the most appropriate generators for the signal and background process, the definition of efficient filters for the simulation of the background and the submission of the relevant requests to the production group.


This work has been an important contribution to the paper [P20] in which an almost 6σ deviation from the null signal hypothesis has been made public by the ATLAS collaboration. The excess in the decay channels γγ, ZZ and WW is compatible with the expectation of a SM Higgs boson of mass 126 GeV. The WW channel has the better accuracy in the determination of the signal strength μ=σmeasuredexpected from SM. The lνlν decay channel dominates the sensitivity and the observed excess in the WW channel.


In September of 2012 my contribution to the Higgs search in the WW channel has been recognized by the collaboration that nominated myself convener of the Higgs subgroup working in the WW channel for the end of 2012 and 2013. The mandate of the group is to measure the properties of the observed boson in the WW channel, the observation of further production channel (VBF, WH/ZH) and the search for heavier Higgs like boson decaying to WW. At the Moriond QCD conference [o1, o2] the results of the HSG3 group in the search for the Higgs boson weere presented. An observed excess of 4σ has been reported combining the 0, 1 and 2 jet channels, while a VBF signal of 2.5σ has been observed. Moreover the spin 2+ minimal coupling model has been excluded at > 95% C.L. Combining the WW result with the γγ results [o3] a VBF observation at 3.1σ has been reported [o4]. The set of WW results, produced under my personal coordination and responsibility, together with the γγ and ZZ channels, give a clear identification of the observed excess in [P20] as the Higgs boson responsible of the electroweak symmetry breaking mechanism.
