Search for new physics Beyond Standard Model (BSM) is one of the major goals of the CMS experiments at the LHC. A variety of BSM searches including exotic signatures, narrow resonances such as W' and Z' particles decaying to final states with top quarks and Higgs boson is presented. The results are based on proton-proton collision data collected during Run 2 of the LHC at a centre-of-mass...

The NA62 experiment collected the world's largest dataset of charged kaon decays in 2016-2018, leading to the first measurement of the branching ratio of the ultra-rare $K^+ \rightarrow \pi^+ \nu \bar\nu$ decay, based on 20 candidates. This provides evidence for the very rare $K^+ \rightarrow \pi^+ \nu... -

Following the recent update measurement of the W boson mass performed by the CDF-II experiment at Fermilab which indicates 7σ deviation from the SM prediction. As a consequence, the open question is whether there are extensions of the SM that can carry such a remarkable deviation or what phenomenological repercussions this has. In this paper, we investigate what the theoretical constraints...

While experimental data has not ruled out the possibility of additional Higgs bosons or gauge sectors, several alternative models have been proposed to go beyond the standard model and tackle the question of hierarchy. These models predict the existence of heavy vector-like partner quarks that exhibit vector-axial (V-A) coupling, typically on the TeV scale. In this work, we use simplified...

In light of the recent deviation in the W boson mass measurement from the CDF-II, which significantly strays from the Standard Model (SM) prediction, our paper explores the implications of this within the framework of the Two-Higgs Doublet Model (2HDM). We focus on the scenario where the heavy CP-even H is recognized as the Higgs boson observed at 125 GeV.
Our analysis, which incorporates...

Most of the current experimental searches for charged Higgs bosons at the Large Hadron Collider (LHC) concentrate upon the $tb$ and $\tau\nu$ decay channels. In this study, we analyze the feasibility of the bosonic decay channel $W^{\pm (*)} h$ instead, with the charged gauge boson being either on-shell or off-shell and $h$ being a neutral light Higgs boson. Focusing on the Two-Higgs Doublet...

The aim of this study is to examine the impact of the Z+photon and Di-photon signal strength measurements, $\mu_{\gamma\gamma}$ and $u_{\gamma Z}$, on the allowed parameter space of the Inert Doublet Model (IDM). Specifically, we focus on the effect of these measurements on the second doublet mass $\mu_2^2$, and also their compatibility with the most recent constraint from the XENON1T...
