A very light (GeV scale) dark gauge boson ($Z$) is a recently highlighted hypothetical particle that can address some astrophysical anomalies as well as the $3.6 sigma$ deviation in the muon $g$-2 measurement. We suggest top quark decays as a venue to search for light dark force carriers at the LHC. Such $Z$s can be easily boosted, and they can decay into highly collimated leptons (lepton-jet) with large branching ratio. We investigate a scenario where a top quark decays to $b W$ accompanied by one or multiple dark force carriers and find that such a scenario could be easily probed at the early stage of LHC Run 2.
Extending the Standard Model (SM) scalar sector via one or multiple Higgs field(s) in higher representation brings one or more charged Higgs bosons in the spectrum. Some of these gauge representations with appropriate hypercharge can bring up doubly
Recent results on MSSM Higgs physics at the LHC are reviewed. The dependence of the LHC discovery reach in the bbar b H/A, H/A to tau^+tau^- channel on the underlying SUSY scenario is analysed. This is done by combining the latest results for the pro
The search for heavy Higgs bosons is an essential step in the exploration of the Higgs sector and in probing the Supersymmetric parameter space. This paper discusses the constraints on the M(A) and tan beta parameters derived from the bounds on the d
Non-minimal Higgs sectors are strongly constrained by the agreement of the measured couplings of the 125 GeV Higgs with Standard Model predictions. This agreement can be explained by an approximate $mathbb{Z}_2$ symmetry under which the additional Hi
Left-Right twin Higgs(LRTH) model predicts the existence of a pair of charged Higgs $phi^{pm}$. In this paper, we study the production of the charged Higgs bosons pair $phi^{pm}$ via the process $e^{+}e^{-}to phi^{+}phi^{-}$ at the International Line
