The Standard Model (SM) of particle physics effectively describes fundamental particles and their interactions through various forces.The phenomenological implications of the BLSSM are examined, focusing on Higgs production and decay at the LHC, while new particles, such as a heavy Z, and neutrino mass generation via a seesaw mechanism are also predicted.The analysis includes the pp->H->bb signal, reviewing its luminosity-normalized yield against major backgrounds and evaluating kinematic distributions like invariant mass, transverse momentum, and angular separation for different Higgs hypotheses.

The Standard Model (SM) of particle physics effectively describes fundamental particles and their interactions through various forces. This document analyzes the Beyond the Standard Model (BLSSM) and its extended Higgs sector, which includes additional Higgs states, and discusses their unique collider signatures in comparison to the SM and Minimal Supersymmetric Standard Model (MSSM). A comprehensive overview of the Large Hadron Collider (LHC) is provided, detailing its design, collision mechanics, and operational energies (13-14 TeV). The study of BSM theories, particularly supersymmetry and its extensions, is motivated by the SM's limitations. The BLSSM offers solutions while maintaining the SM's predictive accuracy.
