Phenomenology of supersymmetry with broken R-parity [PDF]
Physics Letters B, 1985 In some phenomenological supersymmetric models R-parity (+1 for particles, -1 for sparticles) is spontaneously broken along with tau-lepton number Lτ by a vacuum expectation value υτ of the tau sneutrino ντ. To avoid excess stellar energy loss through majorons, there should also be explicit Lτ violation through right-handed neutrinos.

Journal of High Energy Physics, 2018 Recently, a new minimal extension of the Standard Model has been proposed, where a spontaneously broken, flavor-dependent global U(1) symmetry is introduced.

Proton decay: flipped vs. unflipped SU(5)
Journal of High Energy Physics, 2020 We analyze nucleon decay modes in a no-scale supersymmetric flipped SU(5) GUT model, and contrast them with the predictions for proton decays via dimension-6 operators in a standard unflipped supersymmetric SU(5) GUT model.

Gauge mediated supersymmetry breaking and the cosmology of Left-Right symmetric model
, 2008 Left-Right symmetry including supersymmetry presents an important class of gauge models which may possess natural solutions to many issues of phenomenology. Cosmology of such models indicates a phase transition accompanied by domain walls.

Explaining electron and muon g − 2 anomaly in SUSY without lepton-flavor mixings
Journal of High Energy Physics, 2019 We propose a SUSY scenario to explain the current electron and muon g − 2 discrepancies without introducing lepton flavor mixings. Threshold corrections to the Yukawa couplings can enhance the electron g − 2 and flip the sign of the SUSY contributions ...

Resonant Higgs pair production as a probe of stop at the LHC
Journal of High Energy Physics, 2017 Searching for top squark (stop) is a crucial task of the LHC. When the flavor conserving two body decays of the stop are kinematically forbidden, the stops produced near the threshold will live long enough to form bound states which subsequently decay ...

Mass hierarchy from the flavor symmetry in supersymmetric multi-Higgs doublet model
Journal of High Energy Physics, 2020 We study the supersymmetric standard model with multiple Higgs doublets with gauged U(1) X flavor symmetry. When the flavor symmetry is broken by the vacuum expectation value of flavon, the ℤ3 symmetry M 3 called matter triality remains and it prohibits ...

, 2006 We present a supersymmetric realization of the twin Higgs mechanism, which cancels off all contributions to the Higgs mass generated above a scale f. Radiative corrections induced by the top quark sector lead to a breaking of the twin sector electroweak ...

Multilepton signals of heavier electroweakinos at the LHC
Journal of High Energy Physics, 2017 As a sequel to our recent paper we examine the phenomenology of the full electroweakino sector of the pMSSM without invoking the ad hoc but often employed assumption that the heavier ones are decoupled.

The non-Universal U(1) gauge extended μνSSM: anomalies cancellation and singular phenomenology
Journal of High Energy Physics, 2018 So far the most sophisticated experiments have shown no trace of new physics at the TeV scale. Consequently, new models with unexplored parameter regions are necessary to explain current results, re-examine the existing data, and propose new experiments.
