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.

Dark matter, sparticle spectroscopy and muon (g − 2) in SU(4) c × SU(2) L × SU(2) R
Journal of High Energy Physics, 2018 We explore the sparticle mass spectra including LSP dark matter within the framework of supersymmetric SU(4) c × SU(2) L × SU(2) R (422) models, taking into account the constraints from extensive LHC and cold dark matter searches.

E6 motivated UMSSM confronts experimental data
Journal of High Energy Physics, 2020 We test E 6 realisations of a generic U(1)′ extended Minimal Supersymmetric Standard Model (UMSSM), parametrised in terms of the mixing angle pertaining to the new U(1)′ sector, θ E 6 $$ {\theta}_{E_6} $$ , against all currently available data, from ...

Analysis of the TeV-scale mirage mediation with heavy superparticles
Journal of High Energy Physics, 2017 We discuss effective models derived from a supersymmetric model whose mediation mechanism of supersymmetry (SUSY) breaking is namely mirage mediation.

A supersymmetric theory of baryogenesis and sterile sneutrino dark matter from B mesons
Journal of High Energy Physics, 2020 Low-scale baryogenesis and dark matter generation can occur via the production of neutral B mesons at MeV temperatures in the early Universe, which undergo CP-violating oscillations and subsequently decay into a dark sector.

Solving the muon g-2 anomaly in CMSSM extension with non-universal gaugino masses
Journal of High Energy Physics, 2018 We propose to generate non-universal gaugino masses in SU(5) Grand Unified Theory (GUT) with the generalized Planck-scale mediation SUSY breaking mechanism, in which the non-universality arises from proper wavefunction normalization with lowest component

Expanding the parameter space of natural supersymmetry
Journal of High Energy Physics, 2020 SUSY/SUGRA models with naturalness defined via small μ are constrained due to experiment on the relic density and the experimental limits on the WIMP-proton cross-section and WIMP annihilation cross-section from indirect detection experiments ...

Long-lived stau, sneutrino dark matter and right-slepton spectrum
Journal of High Energy Physics, 2018 The minimal supersymmetric (SUSY) standard model (MSSM) augmented by right chiral sneutrinos may lead to one such sneutrino serving as the lightest supersymmetric particle and a non-thermal dark matter candidate, especially if neutrinos have Dirac masses

Supersymmetry Phenomenology: A Microreview
, 1995 We briefly review the current status and future prospects for supersymmetry searches at colliders, and discuss strategies by which further information about sparticle properties may be obtained at the LHC.
