  1. 169. Study of high-energy hadronic interactions with the Pierre Auger Observatory

    The Pierre Auger Observatory is the largest facility in the world to observe ultra-high-energy cosmic rays. Its hybrid detection technique combines the observation of the longitudinal development of the shower in the atmosphere and the measurement of the lateral distribution of particles that arrive at the ground. This has allowed the Auger Collaboration to test hadronic interactions that...

    The distribution of arrival directions of high-energy cosmic rays carries major clues to understanding their origin. The Pierre Auger Observatory, the largest cosmic-ray observatory in the world, collected an unprecedentedly large data set over 17 years of operation. In this work, we describe anisotropy-related results obtained by using such events. These are the large-scale searches in the...

  3. 170. Search for dark photons in heavy-ion collisions

    Search for the dark matter (DM) candidates is one of the growing direction of the experimental and theoretical research in heavy-ion physics [1]. The vector 𝑈-bosons, or so called 'dark photons', are one of the possible candidates for the dark matter mediators. They are supposed to interact with the standard matter via a 'vector portal' due to the 𝑈(1)−𝑈(1)′ symmetry group mixing which might...

  4. 173. Dark sector of an extended 2HDM with Q4 symmetric matter

    parallel

    We describe the phenomenology of the scalar and dark matter sectors of an extended 2HDM with Q4 symmetry among the SM fermions. The model features a Higgs portal to a dark sector comprised of heavy right handed neutrinos. We discuss relic abundance as well as direct detection constraints on the DM candidate.

  5. 171. Searches for Dark Matter with the ATLAS Experiment at the LHC

    parallel

    The presence of a non-baryonic Dark Matter (DM) component in the Universe is inferred from the observation of its gravitational interaction. If Dark Matter interacts weakly with the Standard Model (SM) it could be produced at the LHC. The ATLAS Collaboration has developed a broad search program for DM candidates in final states with large missing transverse momentum produced in association...
