A possible connection between neutrino mass generation and the lightness of a NMSSM pseudoscalar
Asmaa Abada, Gautam Bhattacharyya, Debottam Das +1
One of the interesting properties of the NMSSM is that it can accommodate a light pseudoscalar of order 10 GeV. However, such scenarios are challenged by several experimental const…
Light dark matter in the NMSSM: upper bounds on direct detection cross sections
Debottam Das, Ulrich Ellwanger
In the Next-to-Minimal Supersymmetric Standard Model, a bino-like LSP can be as light as a few GeV and satisfy WMAP constraints on the dark matter relic density in the presence of…
Exploring SUSY light Higgs boson scenarios via dark matter experiments
Debottam Das, Andreas Goudelis, Yann Mambrini
We examine the dark matter phenomenology in supersymmetric light higgs boson scenarios, adapting nonuniversal Higgs masses at the gauge coupling unification scale. The correct reli…
Probing the light Higgs pole resonance annihilation of dark matter in the light of XENON100 and CDMS-II observations
Utpal Chattopadhyay, Debottam Das, Dilip Kumar Ghosh +1
We consider the prospect of lightest neutralino () as a dark matter candidate in the light of recent interesting observations from the XENON100 and CDMS-II experime…
One-loop contribution to the neutrino mass matrix in NMSSM with right-handed neutrinos and tri-bimaximal mixing
Debottam Das, Sourov Roy
Neutrino mass patterns and mixing have been studied in the context of next-to-minimal supersymmetric standard model (NMSSM) with three gauge singlet neutrino superfields. We consid…
