In this study, we investigate the constraints imposed on the Doublet Left-Right Symmetric Model (DLRSM) by the latest experimental data on the Higgs boson. While most previous studies have assumed small values for the ratios $r=\kappa_2/\kappa_1$ and $w=v_L/\kappa_1$, we consider the most general scalar potential and explore the constraints on $r$ and $w$. Through our analysis, we calculate...
The CMS collaboration has recently reported the final Run 2 results of the low-mass Higgs-boson search in the di-photon channel. The new results show an excess of events at a mass of about 95 GeV with a local significance of $2.9\sigma$, confirming a previously reported excess at about the same mass and similar significance based on the first-year Run 2 plus Run 1 data. In this work, we...
Though the Standard Model (SM) provides a very elegant description of interactions among fundamental particles, there are ample evidences to believe that there exists physics beyond the Standard Model. In particular extending the scalar sector has enough motivation from vacuum stability, electroweak phase transition and various other sectors. Among different such extensions, two Higgs doublet...
I briefly review the Benchmark Planes in the Two-Real-Singlet Model (TRSM), a model that enhances the Standard Model (SM) scalar sector by two real singlets that obey a Z2 x Z2' symmetry. In this model, all fields acquire a vacuum expectation value, such that the model contains in total 3 CP-even neutral scalars that can interact with each other. All interactions with SM-like particles are...
Various extensions of the Standard Model predict the existence of additional Higgs bosons. If these additional Higgs bosons are sufficiently heavy, an important search channel is the di-top final state. In this channel interference contributions between the signal and the corresponding QCD background process are expected to be important. If more than one heavy Higgs boson is present, besides...
Searches for dark matter produced via scalar resonances in final states consisting of Standard Model (SM) particles and missing transverse momentum are of high relevance at the LHC. Motivated by dark-matter portal models, most existing searches are optimized for unbalanced decay topologies for which the missing momentum recoils against the visible SM particles. In this work, we show that...
