Higgs Physics

TL;DR

This paper reviews the discovery of the 125 GeV Higgs boson, its implications within the Standard Model and MSSM, and discusses future prospects for Higgs and new physics searches at colliders.

Contribution

It provides a comprehensive summary of Higgs physics post-discovery, including constraints on models and future experimental directions.

Findings

Measured Higgs mass constrains Standard Model parameters

Production and decay rates align with Standard Model predictions

Searches for heavier Higgs states in MSSM are ongoing

Abstract

The implications of the discovery of a scalar Higgs boson at the LHC with a mass of approximately 125 GeV are summarised in the context of the Standard Model of particle physics with its unique scalar boson and of its most celebrated new physics extension, the minimal supersymmetric Standard Model or MSSM, in which the Higgs sector is extended to contain three neutral and two charged scalar bosons. Discussed are the implications from the measured mass, the production and decay rates of the observed particle and, in the MSSM, from the constraints in the search for the heavier Higgs states. The perspectives for Higgs and new physics searches at the next LHC upgrades as well as at future hadron and lepton colliders are then briefly summarized.
