I will discuss measurements of Higgs boson properties with the ATLAS and CMS experiments.
Several theories beyond the Standard Model (BSM) suggest an expanded Higgs sector, prompting investigations for neutral and charged Higgs bosons in addition to the one observed at 125 GeV. The completion of Run 2 of the LHC in 2018 yielded a total of 139 fb^−1 of data, offering an opportunity to delve deeper into the BSM Higgs parameter space. This presentation covers the searches for BSM...
The Standard Model predicts non-resonant production of Higgs boson pairs, which provides a handle to directly measure the shape of the Higgs potential. Numerous BSM models predict new scalar fields with couplings that lead to the simultaneous production of scalar bosons. The ATLAS and CMS Collaborations have active search programs targeting multi-scalar-boson production. This talk provides and...
The most precise determination of the sum of neutrino masses from cosmological data, derived from analysis of the cosmic microwave background and recent baryon acoustic acoustic oscillations data from DESI, favors a value below the minimum inferred from neutrino flavor oscillation experiments. The sum of neutrino mass is determined in cosmology from the suppression of matter clustering in the...
