MSSM soft terms from supergravity with gauged R-symmetry in de Sitter vacuum
Nuclear Physics B, 2016 We work out the phenomenology of a model of supersymmetry breaking in the presence of a tiny (tunable) positive cosmological constant, proposed by the authors in arXiv:1403.1534. It utilizes a single chiral multiplet with a gauged shift symmetry that can

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 ...

Extraction of neutrino Yukawa parameters from displaced vertices of sneutrinos
Journal of High Energy Physics, 2021 We study displaced signatures of sneutrino pairs potentially emerging at the Large Hadron Collider (LHC) in a Next-to-Minimal Supersymmetric Standard Model supplemented with right-handed neutrinos triggering a Type-I seesaw mechanism.

Calculated Event Rates for Axion Detection via Atomic and Nuclear Processes
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 The possibility of detection of 5.5 MeV and 14.4 keV solar axions by observing axion‐induced nuclear and atomic transitions is investigated. The presence of nuclear transitions between spin orbit partners can be manifested by the subsequent deexcitation via gamma ray emissions.

Dirac gauginos in low scale supersymmetry breaking
Nuclear Physics B, 2014 It has been claimed that Dirac gaugino masses are necessary for realistic models of low-scale supersymmetry breaking, and yet very little attention has been paid to the phenomenology of a light gravitino when gauginos have Dirac masses.

Phenomenological implications of supersymmetry breaking by the dilaton [PDF]
Physics Letters B, 1993 We investigate the low energy properties of string vacua with spontaneously broken $N=1$ supersymmetry by a dilaton $F$-term. As a consequence of the universal couplings of the dilaton, the supersymmetric mass spectrum is determined in terms of only three independent parameters and more constrained than in the minimal supersymmetric Standard Model. For

Relaxing the W′ Constraint on Compact Extradimension
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 In this paper, we study the constraint on brane tension and compactification scale for models with brane fluctuations using the results from the direct search of W′ at 13 TeV LHC, with an integrated luminosity of 36.1fb−1, in the case for which branon forms the entire cold dark matter.

Tachyonic de Sitter Solutions of 10d Type II Supergravities
Fortschritte der Physik, Volume 69, Issue 7, July 2021., 2021 Abstract Cosmological models of the early or late universe exhibit (quasi) de Sitter space‐times with different stability properties. Considering models derived from string theory, the swampland program does not provide for now a definite characterisation of this stability.
