Searching for Leptoquarks at IceCube and the LHC
Ujjal Kumar Dey, Deepak Kar, Manimala Mitra +2
In the light of recent experimental results from IceCube, LHC searches for scalar leptoquark, and the flavor anomalies and , we analyze two scalar leptoquark models…
Quark mixing in an symmetric model with two Higgs doublets
Dipankar Das, Ujjal Kumar Dey, Palash B. Pal
We construct a model where the smallness of the masses of first quark generations implies the near block diagonal nature of the CKM matrix and vice-versa. For this set-up, we rely…
Dark Energy from pNGB Mediated Dirac Neutrino Condensate
Ujjal Kumar Dey, Tirtha Sankar Ray, Utpal Sarkar
We consider an extension of the Standard Model that provide an unified description of eV scale neutrino mass and dark energy. An explicit model is presented by augmenting the Stand…
Multi-component Fermionic Dark Matter and IceCube PeV scale Neutrinos in Left-Right Model with Gauge Unification
Debasish Borah, Arnab Dasgupta, Ujjal Kumar Dey +2
We consider a simple extension of the minimal left-right symmetric model (LRSM) in order to explain the PeV neutrino events seen at the IceCube experiment from a heavy decaying dar…
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…
