Effects of QCD Equation of State on the Stochastic Gravitational Wave Background
Sampurn Anand, Ujjal Kumar Dey, Subhendra Mohanty
Cosmological phase transitions can be a source of Stochastic Gravitational Wave (SGW) background. Apart from the dynamics of the phase transition, the characteristic frequency and…
Light Dark Matter through Assisted Annihilation
Ujjal Kumar Dey, Tarak Nath Maity, Tirtha Sankar Ray
In this paper we investigate light dark matter scenarios where annihilation to Standard Model particles at tree-level is kinematically forbidden. In such cases annihilation can be…
Plateau Inflation in -parity Violating MSSM
Girish Kumar Chakravarty, Ujjal Kumar Dey, Gaetano Lambiase +1
Inflation with plateau potentials give the best fit to the CMB observables as they predict tensor to scalar ratio stringently bounded by the observations from Planck and BICEP2/Kec…
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…
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…
