 THE LASER INTERFEROMETER SPACE ANTENNA TO EXPLORE THE INVISIBLE UNIVERSE (followed by Library Talk event with the speaker at 17:30) / Colpi, Monica (speaker) (Università degli Studi di Milano-Bicocca, Milano (IT)) The Laser Interferometer Space Antenna (LISA) - a gigameter scale space-based gravitational wave observatory -  will explore the gravitational wave universe in the band from below 0.1 mHz to above 0.1 Hz. LISA will grant us access to a huge cosmological volume with unprecedented reach deep into space, detecting signals up to redshifts 20-30 and even beyond if sources exist.  LISA will detect massive black hole coalescences to unveil the yet unknown origins of the first quasars and to shed light into the teeming population of middleweight black holes forming in galactic dark matter halos [...] 2021 - 0:59:00.

The CMS Collaboration has looked for hints of top squark production in fully hadronic, semi-leptonic and fully leptonic final states with the whole dataset of proton-proton collisions collected during the Run 2 of the LHC [...] 2021 - 1:06:36.

Long-lived particles are predicted by models including anomaly or gravity-mediated supersymmetry-breaking scenarios, split supersymmetry, as well as models featuring exotic decays of the Higgs boson [...] 2021 - 1:05:32.

The present most accurate $a_\mu$ measurement was carried out by the E821 Experiment at Brookhaven (USA), resulting in a 3.7 standard deviation discrepancy with the theoretical prediction of the Standard Model of particle physics [...] 2021 - 2:01:41.

 Beauty and charm production in pp collisions via D-meson measurements with ALICE / Catalano, Fabio (speaker) (Politecnico e INFN Torino (IT)) Measurements of the production of hadrons containing charm or beauty quarks in proton-proton collisions provide an important test of quantum chromodynamics calculations. They also set the reference for the respective measurements in heavy-ion collisions, where the formation and properties of the quark-gluon plasma are investigated. The excellent particle identification, track and decay-vertex reconstruction capabilities of the ALICE experiment, together with machine-learning techniques for multi-class classification, are exploited to separate the signal of non-prompt D mesons (produced in beauty-hadron decays) from that of prompt D mesons (produced in the charm-quark fragmentation) and the combinatorial background [...] 2021 - 0:52:40.
