We investigate the light charged Higgs boson production via $pp \rightarrow H^\pm h$ at the Large Hadron Collider (LHC) in the Two-Higgs Doublet Model (2HDM) type-I. By focusing on a scenario where $H$ is the observed Higgs boson of mass 125 GeV, we study the aforementioned Higgs boson production channel and explore its bosonic decay $H^\pm \righta...

Motivated by the new CDF measurement of the $W$ boson mass reported recently which clearly illustrates a large deviation compared to the Standard Model (SM) prediction. In the present paper, we study the Two-Higgs Doublet Model (2HDM) contributions to $M_W$ and its phenomenological implications in the case where the heavy CP-even $H$ is identified...

We compute the full one-loop radiative corrections for charged Higgs pair production $e^{+}e^{-}\to H^{+}H^{-}$ in the Inert Higgs Doublet Model. The on-shell renormalization scheme have been used. We include the full electroweak contributions as well as the QED corrections (soft and hard). We use FeynArts/FormCalc/LoopTools to compute the one-loop...

We present a comprehensive study on Higgs pair production in various archetypical extended Higgs sectors such as the real and the complex 2-Higgs-Doublet Model, the 2-Higgs-Doublet Model augmented by a real singlet field and the Next-to-Minimal Supersymmetric extension of the Standard Model. Taking into account all relevant theoretical and experime...

We study the phenomenology of the scotogenic model in the case of a Majorana dark matter (DM) candidate. This scenario gives important consequences since the parameter space of the model is almost unconstrained compared to the inert Higgs doublet model (or the scotogenic model with scalar DM) and hence offers new opportunities for discovery at futu...
