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…
Searching exotic Higgs bosons at the LHC
Gautam Bhattacharyya, Siddharth Dwivedi, Dilip Kumar Ghosh +2
We analyse in a model independent way the possibilities of digging out neutral exotic Higgs states, should they exist endowed with unconventional couplings with ordinary matter and…
Signals for vector-like leptons in an -symmetric 2HDM at ILC
Indrani Chakraborty, Dilip Kumar Ghosh, Nivedita Ghosh +1
In this work, we explore the signals of an -symmetric two Higgs doublet model with two generations of vector-like leptons (VLLs) at the proposed International Linear Collider…
