Strong first order electroweak phase transition in 2HDM confronting future Z & Higgs factories

Journal of High Energy Physics, 2021
The electroweak phase transition can be made first order by extending the Standard Model (SM) Higgs sector with extra scalars. The same new physics can explain the matter-antimatter asymmetry of the universe by supplying an extra source of CP violation ...

Probing minimal SUSY scenarios in the light of muon g−2 and dark matter

Journal of High Energy Physics, 2017
We study supersymmetric (SUSY) models in which the muon g −2 discrepancy and the dark matter relic abundance are simultaneously explained. The muon g − 2 discrepancy, or a 3σ deviation between the experimental and theoretical results of the muon ...

Muon g − 2 in gauge mediation without SUSY CP problem

Journal of High Energy Physics, 2021
We discuss gauge mediated supersymmetry breaking models which explain the observed muon anomalous magnetic moment and the Higgs boson mass simultaneously.

Gluino-mediated electroweak penguin with flavor-violating trilinear couplings

Journal of High Energy Physics, 2018
In light of a discrepancy of the direct CP violation in K → ππ decays, ε ′ /ε K , we investigate gluino contributions to the electroweak penguin, where flavor violations are induced by squark trilinear couplings.

Digging deeper for new physics in the LHC data

Journal of High Energy Physics, 2017
In this paper, we describe a novel, model-independent technique of “rectangular aggregations” for mining the LHC data for hints of new physics. A typical (CMS) search now has hundreds of signal regions, which can obscure potentially interesting anomalies.

Phenomenology of supersymmetry with scalar sequestering [PDF]

Physical Review D, 2009
The defining feature of scalar sequestering is that the minimal supersymmetric standard model squark and slepton masses as well as all entries of the scalar Higgs mass matrix vanish at some high scale. This ultraviolet boundary condition--scalar masses vanish while gaugino and Higgsino masses are unsuppressed--is independent of the supersymmetry ...

Detection prospects of light pseudoscalar Higgs boson at the LHC

Journal of High Energy Physics, 2017
The discovery potential of light pseudo scalar Higgs boson for the mass range 10-60 GeV is explored. In the context of the next-to-minimal supersymmetric standard (NMSSM) model, the branching fraction of light pseudo scalar Higgs boson decaying to a pair
