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…
Leptoquarks: 750 GeV Diphoton Resonance and IceCube Events
Ujjal Kumar Dey, Subhendra Mohanty, Gaurav Tomar
The recent data from ATLAS and CMS hint at a new resonance at around 750 GeV in the diphoton invariant mass distribution. The explanation of the significantly large cross section f…
Rare Top Decays in Minimal and Non-minimal Universal Extra Dimension
Ujjal Kumar Dey, Tapoja Jha
The flavour changing decays of the top quark are severely suppressed in the Standard Model by virtue of the Glashow-Iliopoulos-Maiani mechanism. Many beyond Standard Model extensio…
