Dilution of Dark Matter Relic abundance due to First Order Electroweak Phase Transition
Subhojit Roy
We investigate the effect of a first-order electroweak phase transition (FOEWPT), which is one of the prerequisites for electroweak baryogenesis, on the thermal relic abundance of…
Interplay among gravitational waves, dark matter and collider signals in the singlet scalar extended type-II seesaw model
Purusottam Ghosh, Tathagata Ghosh, Subhojit Roy
We study the prospect of simultaneous explanation of tiny neutrino masses, dark matter (DM), and the observed baryon asymmetry of the Universe in a -symmetric complex singlet…
Hunting ewinos and a light scalar of -NMSSM with a bino-like dark matter in top squark decays at the LHC
AseshKrishna Datta, Monoranjan Guchait, Arnab Roy +1
We study the prospects of a simultaneous hunt at the Large Hadron Collider (LHC) of relatively light electroweakinos and a singlet-like scalar of the -symmetric Next-to-Minima…
Electroweak Phase Transition in the -invariant NMSSM: Implications of LHC and Dark matter searches and prospects of detecting the gravitational waves
Arindam Chatterjee, AseshKrishna Datta, Subhojit Roy
We study in detail the viability and the patterns of a strong first-order electroweak phase transition as a prerequisite to electroweak baryogenesis in the framework of -invar…
