Soft leptogenesis in the NMSSM with a singlet right-handed neutrino superfield
Waleed Abdallah, Abhass Kumar, Abhijit Kumar Saha
In this work, we explore soft leptogenesis in the NMSSM framework extended by a right-handed neutrino superfield. We calculate the CP asymmetry, , and find it to be no…
Dark Matter Spin Characterisation in Mono- Channels
W. Abdallah, A. Hammad, S. Khalil +1
The Supersymmetric Standard Model (BLSSM) is an ideal testing ground of the spin nature of Dark Matter (DM) as it offers amongst its candidates both a spin-1/2 (the lightest…
Revisiting singlino dark matter of the natural -symmetric NMSSM in the light of LHC
Waleed Abdallah, Arindam Chatterjee, AseshKrishna Datta
Inspired by the fact that relatively small values of the effective higgsino mass parameter of the -symmetric Next-to-Minimal Supersymmetric Standard Model (NMSSM) could render…
FIMP dark matter candidate(s) in a model with inverse seesaw mechanism
Waleed Abdallah, Sandhya Choubey, Sarif Khan
The non-thermal dark matter (DM) production via the so-called freeze-in mechanism provides a simple alternative to the standard thermal WIMP scenario. In this work, we consider a p…
