Constraints on the model from a negative number of flavors
Daniele Artico, Jasper Roosmale Nepveu
Treating the number of flavors as a variable in the model leads to non-perturbative constraints on the spectrum of operators. Using the duality between and $Sp(-n…
Status of light inflaton: from inflation to laboratory
Niloy Mondal, Shashwat Sharma, Mathew Thomas Arun +1
We investigate the viability of the light inflaton scenario in light of the latest inflationary constraints from the Atacama Cosmology Telescope (ACT), together with bounds from co…
From WIMP to FIMP during reheating: collider vs non-collider probes for p-wave annihilation
Dipankar Pradhan, Niloy Mondal, Abhik Sarkar +4
By examining the transition from freeze-out to freeze-in dark matter (DM) production within the framework of perturbative reheating, where DM interacts with the visible sector thro…
Singlet-doublet dark matter induced radiative neutrino mass and TeV scale leptogenesis
Partha Kumar Paul, Narendra Sahu, Shashwat Sharma
The singlet-doublet dark matter (SDDM) model is a well-motivated WIMP framework that accommodates viable dark matter over a broad range of parameter space. In this work, we explore…
