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…
Comprehensive Constraints on ALP Couplings from future Colliders, Muon , Thermal Dark Matter and Higgs Measurements
Pramod Sharma, Soham Singh, Mukesh Kumar +1
In this article, we present projected 95\% C.L. limits on Axion-Like Particle (ALP) couplings from ALP production at a future collider operating at $\sqrt{s} = 250~\text{G…
Higgs Decay Signal Strengths in an Extended 2HDM
Hrishabh Bharadwaj, Mamta Dahiya, Sukanta Dutta +1
The combined CMS and ATLAS analysis of \(h \to Zγ\) reveals a \(2Ï\) excess over the Standard Model (SM) prediction, hinting at potential new physics. In contrast, the observed a…
mass and Muon in Inert 2HDM Extended by Singlet Complex Scalar
Hrishabh Bharadwaj, Mamta Dahiya, Sukanta Dutta +1
The deviations of the recent measurements of the muon magnetic moment and the boson mass from their SM predictions hint to new physics beyond the SM. In this article, we addres…
