T 41.1: Invited Overview Talk

One of a kind: the Higgs boson — •Matteo Bonanomi — Universität Hamburg

Discovered by the ATLAS and CMS experiments nearly 60 years after its prediction, the Higgs boson is a cornerstone of the Standard Model of particle physics.

What began as the challenge of discovering a rare particle has now become a vast program of precision measurements which have enabled a deep understanding of the origin of particle masses, the observation of rare Higgs couplings, and a highly granular characterization of the Higgs boson properties with unprecedented precision. This has only been possible thanks to sophisticated detector technologies and great advances in analyses techniques.

Today, experimental efforts are increasingly focused on the simultaneous production of multiple Higgs bosons. The observation of this process would provide direct insight into the Higgs self-interaction and could shed light on fundamental open questions about the origin and evolution of the Universe.

In this talk, I will provide an experimental overview of the field and highlight recent progress of the ATLAS and CMS Collaborations to understand and characterize this one-of-a-kind particle. In the final part of the talk, I will also discuss the experimental prospects for the ongoing Run III and the upcoming High-Luminosity phases of the LHC.
