Dark Photon - ALP Freeze-in: 511 keV and H Constraints
Simran Arora, Nandini Das, Sukanta Dutta +1
We investigate a freeze-in scenario of two component dark matter consisting of an axion-like particle (ALP) and a dark photon. The dark sector connects to the Standard Model throug…
Embedding Generalized CP Symmetry in One Zero Texture Neutrino Mass Models
Priya, Simran Arora, B. C. Chauhan
In this study, we investigate one zero textures within the framework of generalized CP symmetry associated with the complex tribimaximal matrix. By combining these approaches, we d…
The eV-Scale Sterile Neutrino and Neutrinoless Double Beta Decay
Priya, Simran Arora, B. C. Chauhan
In short-baseline experiments such as LSND and MiniBooNE, an excess of electron neutrinos has been observed, originating from a muon neutrino beam. To address this anomaly, in the…
Leptogenesis from Dark Matter Coannihilation
Simran Arora, Debasish Borah, Arnab Dasgupta +2
We propose a minimal extension of the type-I seesaw model to realise leptogenesis from the co-annihilation of dark sector particles. The type-I seesaw model is extended with a sing…
TeV Scale Resonant Leptogenesis with triplet Fermion in Connection to Muon
Simran Arora, Devabrat Mahanta, B. C. Chauhan
We propose an extension of the minimal scotogenic model with a triplet fermion and a singlet scalar. An imposed symmetry allows only diagonal Yukawa couplings a…
