  Recently, ATLAS and CMS experiments at the LHC put on light the relevant
results in the measurement precision of the Higgs and BSM. In such a report,
where the resonance direct search was made in the $\gamma Z$ channel, a mass
adjustment distribution for the reconstructed $Z$ boson and photon was
established. Thus, simultaneously with the signal-from-background separation,
the number of events has been perfectly described, and an excess signal
approximately twice that expected by the Standard Model (SM) has been noticed,
which is equivalent to a significance of 2.2 standard deviations. In this
study, we examine how any possible new physics models can explain this excess,
such as the CP-conserving Two-Higgs doublet model (2HDMs), the Inert doublet
model (IDM), and the Higgs triplet model (HTM). While considering the available
theoretical and most recent experimental constraints, the phenomenological
implications of existing extensions beyond the SM are discussed, and prospects
for precision studies of these processes are described. We have found that the
excess could be explained in the BSM framework studied, depending on the
charged and double-charged Higgs boson masses.
