Constraints on electromagnetic form factors of sub-GeV dark matter from the Cosmic Microwave Background anisotropy
Gaetano Lambiase, Subhendra Mohanty, Akhilesh Nautiyal +1
We consider dark matter which have non-zero electromagnetic form factors like electric/magnetic dipole moments and anapole moment for fermionic dark matter and Rayleigh form factor…
Signatures of dark Higgs boson in light fermionic dark matter scenarios
Luc Darmé, Soumya Rao, Leszek Roszkowski
Thermal dark matter scenarios based on light (sub-GeV) fermions typically require the presence of an extra dark sector containing both a massive dark photon along with a dark Higgs…
Light dark sector at colliders and fixed target experiments
Luc Darmé, Soumya Rao, Leszek Roszkowski
Minimal scenarios with light (sub-GeV) thermal dark matter are usually accompanied by a correspondingly light "dark sector". Taking as an example a simple fermionic dark matter mod…
Light dark Higgs boson in minimal sub-GeV dark matter scenarios
Luc Darmé, Soumya Rao, Leszek Roszkowski
Minimal scenarios with light (sub-GeV) dark matter whose relic density is obtained from thermal freeze-out must include new light mediators. In particular, a very well-motivated ca…
Impact of LHC data on muon solutions in vector-like extension of the Constrained MSSM
Arghya Choudhury, Soumya Rao, Leszek Roszkowski
The long-standing discrepancy between the experimental determination by the Muon Collaboration at Brookhaven and the Standard Model predictions for the anomalous magnetic mom…
Effect of electromagnetic dipole dark matter on energy transport in the solar interior
Ben Geytenbeek, Soumya Rao, Pat Scott +4
In recent years, a revised set of solar abundances has led to a discrepancy in the sound-speed profile between helioseismology and theoretical solar models. Conventional solutions…
Gauged model in light of muon anomaly, neutrino mass and dark matter phenomenology
Sudhanwa Patra, Soumya Rao, Nirakar Sahoo +1
Gauged model has been advocated for a long time in light of muon anomaly, which is a more than discrepancy between the experimental measurement and the…
Singlet fermion Dark Matter within Left-Right Model
Sudhanwa Patra, Soumya Rao
We discuss singlet fermion dark matter within a left-right symmetric model promoting baryon and lepton numbers as separate gauge symmetries. We add a simple Dirac fermionic dark ma…
Detecting Dipolar Dark Matter in Beam Dump Experiments
Subhendra Mohanty, Soumya Rao
We study interaction of low mass dark matter within beam dump experiments. In particular we study the dipolar dark matter model which assumes that the dark matter couples to Standa…
Higgsino Dark Matter in Nonuniversal Gaugino Mass Models
Manimala Chakraborti, Utpal Chattopadhyay, Soumya Rao +1
We study two simple and well motivated nonuniversal gaugino mass models, which predict higgsino dark matter. One can account for the observed dark matter relic density along with t…
Non-universal gaugino mass GUT models in the light of dark matter and LHC constraints
Joydeep Chakrabortty, Subhendra Mohanty, Soumya Rao
We perform a comprehensive study of , and supersymmetric GUT models where the gaugino masses are generated through the F-term breaking vacuum expectation val…
130 GeV Gamma Ray Signal in NMSSM by Internal Bremsstrahlung
Gaurav Tomar, Subhendra Mohanty, Soumya Rao
There is a possible γ-ray signal at 130 GeV coming from the Galactic Center as seen by Fermi-LAT experiment. We give a SUSY dark matter model to explain this γ-ray feature in NMSSM…
Reconciling the Muon g-2 and Dark Matter Relic Density with the LHC Results in Nonuniversal Gaugino Mass Models
Subhendra Mohanty, Soumya Rao, D. P. Roy
Relatively light electroweak superparticle masses are required to satisfy the bulk annihilation region of dark matter relic density and account for the observed excess of muon g-2,…
Predictions of a Natural SUSY Dark Matter Model for Direct and Indirect Detection Experiments
Subhendra Mohanty, Soumya Rao, D. P. Roy
The most natural region of cosmologically compatible dark matter relic density in terms of low fine-tuning in a minimal supersymmetric standard model with nonuniversal gaugino mass…
Constraint on super-luminal neutrinos from vacuum Cerenkov processes
Subhendra Mohanty, Soumya Rao
We examine the Cerenkov-like emission of from muon super-luminal muon neutrinos assuming a quadratic energy dependence of the neutrino velocity arising from Lorentz viola…
A simple model for magnetic inelastic dark matter (MiDM)
Sudhanwa Patra, Soumya Rao
A simple model for magnetic inelastic dark matter (MiDM), which is a minimal extension of the standard model with right-handed neutrinos (), a singly charged scalar () and…
Neutrino processes with power law dispersion relations
Subhendra Mohanty, Soumya Rao
We compute various processes involving neutrinos in the initial and/or final state and we assume that neutrinos have energy momentum relation with a general power law $E^2 =p^2+ ξ_…
Relic density and PAMELA events in a heavy wino dark matter model with Sommerfeld effect
Subhendra Mohanty, Soumya Rao, D. P. Roy
In a wino LSP scenario the annihilation cross section of winos gravitationally bound in galaxies can be boosted by a Sommerfeld enhancement factor which arises due to the ladder of…
Dipolar Dark Matter
Eduard Masso, Subhendra Mohanty, Soumya Rao
If dark matter (DM) has non-zero direct or transition, electric or magnetic dipole moment then it can scatter nucleons electromagnetically in direct detection experiments. Using th…
