Higgs boson(s) at the LHC

The Standard Model (SM) of particle physics has been highly successful in describing the fundamental particles and their interactions. The discovery of the Higgs boson at the Large Hadron Collider (LHC) was a significant achievement, which was the last missing piece in SM. However, the Higgs boson self-coupling is yet to be measured. I will discuss its present status and prospects at future LHC runs. Then, I will outline exotic decays of the Higgs boson, still allowed by the current experimental data. The SM Higgs sector is extended further with additional scalars to explain several experimental observations and theoretical issues. One such well-motivated beyond the SM (BSM) model is the minimal supersymmetric extension of the Standard Model (MSSM). While the current runs of the LHC have not yielded any new particles, it serves as a catalyst for refining our search strategies and exploring alternative channels within the allowed parameter space. In this context, I will present BSM Higgs searches and a possible signature in terms of long-lived particles.
