Axion-like particle (ALP) portal freeze-in dark matter confronting ALP search experiments
Dilip Kumar Ghosh, Anish Ghoshal, Sk Jeesun
The relic density of Dark Matter (DM) in the freeze-in scenario is highly dependent on the evolution history of the universe and changes significantly in a non-standard (NS) cosmol…
FIMP Dark Matter from Flavon Portals
K. S. Babu, Shreyashi Chakdar, Nandini Das +2
We investigate the phenomenology of a non-thermal dark matter (DM) candidate in the context of flavor models that explain the hierarchy in the masses and mixings of quarks and lept…
Searching for exotic Higgs bosons from top quark decays at the HL-LHC
Gautam Bhattacharyya, Indrani Chakraborty, Dilip Kumar Ghosh +2
Exotic spin- states with unusual couplings with the gauge and matter fields of the Standard Model are worth exploring at the CERN LHC. Though our approach is largely model indep…
Concealing Dirac neutrinos from cosmic microwave background
Anirban Biswas, Dilip Kumar Ghosh, Dibyendu Nanda
The existence of prolonged radiation domination prior to the Big Bang Nucleosynthesis (BBN), starting just after the inflationary epoch, is not yet established unanimously. If inst…
Long lived inert Higgs in fast expanding universe and its imprint on cosmic microwave background
Dilip Kumar Ghosh, Sk Jeesun, Dibyendu Nanda
Presence of any extra radiation energy density at the time of cosmic microwave background formation can significantly impact the measurement of the effective relativistic neutrino…
Flavon Signatures at the HL-LHC
Marco A. Arroyo-Ureña, Amit Chakraborty, J. Lorenzo Díaz-Cruz +3
The detection of a single Higgs boson at the Large Hadron Collider (LHC) has allowed one to probe some properties of it, including the Yukawa and gauge couplings. However, in order…
