KK-number non-conserving decays: Signal of n = 2 excitations of Extra-Dimensional Models at the LHC
Ujjal Kumar Dey, Amitava Raychaudhuri
In the simplest universal extra-dimension models Kaluza-Klein (KK) parity distinguishes the states with odd and even KK-number. We calculate the coupling of a 2n-level top quark to…
High-scale validity of a two-Higgs doublet scenario: a study including LHC data
Nabarun Chakrabarty, Ujjal Kumar Dey, Biswarup Mukhopadhyaya
We consider the conditions for the validity of a two-Higgs doublet model at high energy scales, together with all other low- and high-energy constraints. The constraints on the par…
Analysis of an extended scalar sector with symmetry
Dipankar Das, Ujjal Kumar Dey
We investigate the scalar potential of a general -symmetric three-Higgs-doublet model. The outcome of our analysis does not depend on the fermionic sector of the model. We ide…
