17. Meson-baryon Scattering in Extended-on-mass-shell Scheme at O(p3)

M. Junxu LU (IPNO)

Talk

The scattering processes of particles have always been one of the focus of attention. Since the fundamental theory for strong interaction, quantum chromodynamics (QCD), was proposed, people are always very curious and enthusiastic to figure out how particles interact, or in another word, scatter with each other in all energy sector. However, as is known to us all, one critical feature of QCD...

15. Study of baryonic resonances in the reaction $pp\rightarrow pp\pi^+\pi^-$ at 3.5 GeV with HADES

Mme Amel Belounnas (PHEN)

Talk

Pion production in NN collisions is one of the sources of information on the NN interaction and on the contribution of nucleon resonances. In particular, two-pion production in the few energy range, carries information both on single and double baryon excitation and on $\pi\pi$ dynamics, which are also useful for the interpretation of dielectron production. Baryonic resonances indeed...

3. The High Granularity Timing Detector for the ATLAS experiment

M. Corentin Allaire (LAL)

Talk

The expected increase of the particle flux at the high luminosity phase of the LHC (HL-LHC) with instantaneous luminosities up to L ≃ 7.5 × 10^{34} cm^{−2} s^{−1} will have a severe impact on the ATLAS deetctor performance. The pile-up is expected to increase on average to 200 interactions per bunch crossing resulting in a vertex density that can be larger than 1.5 per mm.
The reconstruction...

38. The CMS Level-1 Vector Boson Fusion trigger for the LHC Run II

Mme Chiara Amendola (Laboratoire Leprince-Ringuet, Ecole polytechnique)

29/05/2018 12:40

Talk

The CMS experiment implements a sophisticated two-level triggering system composed of a Level-1 trigger, instrumented by custom-design hardware boards, and a software High-Level-Trigger. A new Level-1 trigger architecture with improved performance is now being used, allowing complex correlations to be computed online. The implementation of the first dedicated Vector Boson Fusion trigger...

16. Towards the construction of the new ATLAS inner detector for the HL-LHC upgrade

M. Dmytro Hohov (LAL Université Paris-Sud)

29/05/2018 13:00

Talk

In the context of High Luminosity phase of LHC (Phase-2), envisaged to start in $\sim$2026, it's planned to increase the beam luminosity up to $7.5\cdot10^{34} cm^{-2}s^{-1}$ and collision energy up to 14 TeV in the center of mass to achieve the high-precision results in the project tasks. These conditions will lead to additional requirements especially on an inner part of the ATLAS detector...
