34. Layer intercalibration of the ATLAS electromagnetic calorimeter

M. Antoine Laudrain (LAL-ATLAS)

Talk

The ATLAS electromagnectic calorimeter allows for a precise measurement of electron and photon energy produced during collisions at the LHC. To get an accurate measurement, the reconstructed energy is calibrated over several steps. One of these steps is the inter-calibration of the 3 layers of the calorimeter to correct for electronic cross-talk among cells and possible residual...

7. Search for the SM (and BSM) production of four top quarks in the ATLAS detector at the LHC

Talk

The top quark is the heaviest elementary particle we know. Therefore, it may play a special role in the Standard Model of particle physics. Its Yukawa coupling to
the Higgs boson is close to one, which makes this particle a key element of many theories beyond the Standard Model.

The Large Hadron Collider (LHC), located at CERN (Geneva, Switzerland) is a proton-proton collider with a...

24. Test of Lepton Flavor Universality using b-baryons

M. Vitalii Lisovskyi (LAL)

Talk

In the Standard Model of particle physics, couplings of gauge bosons to leptons of different flavors (electrons, muons and tau leptons) are believed to be identical. However, the recent measurements performed by LHCb Collaboration show hints for Lepton Flavor Universality violation: probabilities of B meson decaying to an (excited) kaon and two muons, and an (excited) kaon and two electrons,...

35. Сharmonium production using decays to hadronic final states at LHCb

M. Andrii Usachov (LAL)

Talk

Non Relativistic QCD (NRQCD) provides so far the most successful framework to describe the production of the $J^{PC}=1^{--}$ quarkonium states. However, a comprehensive description of the production and polarisation of the $J/\psi$ state at Tevatron and LHC in the complete $p_T$ and rapidity range remains a challenge. The heavy quark spin symmetry yields direct links between the long distance...
