| Abstract | ||
| Among the most sensitive investigations of beyond the Standard Model (BSM) physics are searches for Higgs decays into two muons, heavy particle decays into two heavy vector bosons (WW or ZZ), and the predominant decay mode (H to bb), which has been definitively detected. The branching percentage is anticipated to be around 58% for a Higgs boson mass of mH = 125.35 GeV. Despite a reduced detection effectiveness, the signal may remain statistically significant because of the substantial branching ratio. Experimental techniques have been developed to enhance sensitivity to (b b-) decays. Jets originating from bottom quarks may be discerned by secondary vertex tagging . Recently, the CMS collaboration discovered possible evidence of an extra neutral Higgs boson, center-of-mass (CM) energies of √s = 8 and 13 TeV, with a mass between 94 and 98 GeV, in the gluon-fusion initiated channel leading to the di-photon final state (gg →h→ γ) with integrated luminosities of 19.7 and 35.9 fb−1. A resonant pattern with local and global significance of 2.8 and 1.3 standard deviations was found by the CMS team in the Mγγ spectrum at these data, Given this study, the BLSSM a particular extension of the MSSM with a complicated Higgs sector has two Higgs singlets and Higgs doublets, may be able to explain the observed anomaly. | ||
