“…The associated production of vector boson with heavy quarkonia is a key observable for understanding the quarkonium production mechanisms. In this poster we present the first evidence of the production of the Z boson in asso- ciation with a prompt and non-prompt J/ψ meson and measure its production rate in comparison of the inclusive Z production. …”

“…The jet measurements at LHC indicate a presence of "jet quenching" - strong energy loss of fast partons in hot and dense QCD medium. This poster presents measurements of correlated production of neighbouring jets in Pb+Pb collisions. …”

“…Studying the all-hadronic final state with this strategy was used in run-1 to perform a search for new high mass resonances with the ATLAS detector This final state has significantly more statistics than the leptonic and semi-leptonic counterparts allowing the search to explore a higher mass range. This poster will present the strategy and results of the run-1 analysis and briefly discuss the improvements and challenges expected for its run-2 counterpart.…”

“…This poster presents a search for gluino pair production, in which both gluinos decay through virtual third generation squarks, stop or sbottom, into a final state with many b-jets, missing transverse momentum (ETmiss, coming from the lightest neutralino) and, in the case of stop-mediated decays, potentially also isolated leptons. …”

“…The CMS experiment has been designed with a 2-level trigger system the Level 1 Trigger, implemented on custom-designed electronics, and the High Level Trigger, a streamlined version of the CMS offline reconstruction software running on a computer farm. In this poster we will present the performance with the specific algorithms developed to cope with the increasing LHC pile-up and bunch crossing rate using 13 TeV data during 2015, and prospects for improvements brought to both L1T and HLT strategies to meet the new challenges for 2016 scenarios with a peak instantaneous luminosity of $1.2 \times 10^{34} $cm$^{-2}$s$^{-1}$ and 30 pileup events.…”

“…Strong constraints on such processes cannot at present be obtained from data, and therefore their modeling by Monte Carlo simulation as well as the associated uncertainties are important. This poster documents the Monte Carlo samples currently being used in ATLAS for the ttH and ttV (V=W,Z vector bosons) and tt+bottom and charm quark pairs processes for sqrt(s)=13 TeV proton-proton collisions.…”

“…To maximize the separation between the signal and the dominating $\mathrm{t}\overline{\mathrm{t}}$ background each event is reconstructed under a signal and a $\mathrm{t}\overline{\mathrm{t}}$ hypothesis. The poster focuses on the event selection and the reconstruction of events.…”

“…The hardware-based tracking for the trigger (HTT) will use a combination of Associative Memory ASICs and FPGAs to provide the software-based trigger system with access to tracking information. In this poster, we present the requirements, architecture and projected performance of the system in terms of tracking capability, and trigger selection, based on detailed simulations.…”
