HH -> bbtautau study and upgrades for Run 3 in ATLAS

• Davide Fiacco

The di-higgs researches are one of the main goals of the HL-LHC programme. During the Run2 data-taking phase of the LHC, experiments such as ATLAS and CMS leveraged this opportunity to establish constraints on the self-coupling of the Higgs field and subsequently on the Higgs potential. The Run3 data-taking period could bring more interesting improvements on the limits and on the approaches used in the analysis.

A digestible recipe to find Black holes and Neutron stars

• Sebastian Gomez Lopez

This talk intends to give a thorough description of the matched filtering algorithm; our best tool to search for gravitational waves(GWs) generated by compact binary coalescenses. Ever since 2015 the noise floor of GW detectors in the kilohertz band and our data analysis techniques have become adequate to detect signals of such astrophysical sources predicted to have characteristic frequencies in that range by Einstein's General relativity. A detailed mathematical description of the algorithm will be presented, in addition to the importance of numerical relativity and banks of phenomenological waveforms in the processing of current LIGO-Virgo-KAGRA data.
