Neutron stars as thermometers for reheating induced dipole dark matter
Sahabub Jahedi
We investigate the electromagnetic interactions of dipole dark matter (DM) within an effective field theory framework, considering both standard and non-standard cosmological scena…
Electroweak phase transition in SMEFT: Gravitational wave and collider complementarity
Sahabub Jahedi, Indrajit Saha, Abhik Sarkar
We study the first-order electroweak phase transition (FO-EWPT) within the Standard Model Effective Field Theory (SMEFT) framework induced by dimension-6 operators. Such phenomena…
Probing ALP-portal fermionic dark matter at the colliders
Subhaditya Bhattacharya, Sahabub Jahedi, Soumen Kumar Manna +1
Axion-like particles (ALPs) are promising candidates for mediating interactions between a dark sector and the Standard Model (SM). In this work, considering the effective interacti…
Charged lepton flavor violating decays with a pair of light dark matter and muonium invisible decay
Sahabub Jahedi, Yi Liao, Xiao-Dong Ma
In this paper, we initiate the study of lepton flavor violating (LFV) dark matter (DM) interactions, expanding our focus beyond the flavor-conserving DM interactions typically cons…
Systematic study of lepton-flavor-violating dark matter interactions via indirect detection in effective field theories
Sahabub Jahedi, Jin-Han Liang, Yi Liao +2
Lepton-flavor-violating (LFV) interactions involving dark matter (DM) particles remain a largely unexplored area. In this study, we systematically investigate LFV DM interactions w…
Multi-messenger FIMP
Debasish Borah, Nayan Das, Sahabub Jahedi +1
We propose a multi-messenger frontier probe of non-thermal or freeze-in massive particle (FIMP) dark matter (DM) by considering an effective field theory (EFT) setup. Assuming lept…
