 Search for Rare Decays of the Observed Higgs Boson and Additional Higgs Bosons with the ATLAS Detector / Kano, Y (Nagoya U.) /ATLAS Collaboration Searches for rare decays of the Standard Model Higgs boson and additional Higgs bosons are performed by the ATLAS experiment at the LHC. They use the unprecedented amount of collision data collected during the LHC $pp$ collision run at $\sqrt{s}=13$ TeV in 2015–2018, corresponding to an integrated luminosity of $139\text{ fb}^{-1}$ after the data quality requirements.

 Latest results for Proton-proton Cross Section Measurements with the TOTEM experiment at LHC / Cafagna, Francesco S (INFN, Bari) /TOTEM Collaboration The precise knowledge of the proton-proton cross section is extremely important to model the development, in the atmosphere, of the showers induced by the interaction of ultra high energy cosmic rays.The TOTEM (TOTal cross section, Elastic scattering and diffraction dissociation Measurement at the LHC) experiment, located at the interaction point 5 of the LHC, has measured the total, elastic and inelastic proton-proton cross-sections, using a luminosity independent method, based on the optical theorem, in a center-of-mass energy range from 2.76 to 13 TeV. The elastic scattering was investigated in a wide range of the squared four-momentum transfer |t| allowing the study of Coulomb-nuclear interference region down to |t| ~8 x $$10^{-4} GeV^{2}$$.

 Geant4 quartz fiber simulations as part of luminometer development for CMS / Selivanova, D A (Moscow Phys. Eng. Inst.) ; Popova, E V (Moscow Phys. Eng. Inst.) ; Ilyin, A L (Moscow Phys. Eng. Inst.) ; Aydilek, O (Istanbul U.) ; Ozkorucuklu, S (Istanbul U.) ; Cerci, S (Adiyaman U.) ; Cerci, D Sunar (Adiyaman U.) Measurements of luminosity are required to be exceedingly accurate for the new upcoming era of the LHC with higher energies and a more complex structure of the beam (HL-LHC). A new device is being developed for the CMS experiment to fulfill demands of being stand-alone and precise. [...] 2020 - 6 p. - Published in : J. Phys. : Conf.
