Improved limits on the hadronic and semi-hadronic CP violating parameters and role of a dark force carrier in the electric dipole moment of Hg
B. K. Sahoo
Combining the recently reported electric dipole moment (EDM) of Hg atom due to breaking of parity and time-reversal symmetries with the improved relativistic atomic calcula…
Demystifying the compressed top squark region with kinematic variables
Partha Konar, Tanmoy Mondal, Abhaya Kumar Swain
The ongoing perplexing scenario with no hints of new physics at the Large Hadron Collider can be elucidated amicably if the exotic particle spectrum in many of the well-motivated t…
Exploring CP phase in -lepton Yukawa coupling in Higgs decays at the LHC
Akanksha Bhardwaj, Partha Konar, Pankaj Sharma +1
We study the prospect of determining the CP violating phase in -lepton Yukawa coupling at the Large Hadron Collider (LHC). While the current run is already exploring the product…

The phenomenological study of neutral heavy gauge boson () of the minimal B-L extension was done on the dimuon production channel of the LHC. The study begins wit…
Heavy quarkonium moving in hot and dense deconfined nuclear matter
Lata Thakur, Najmul Haque, Hiranmaya Mishra
We study the behavior of the complex potential between a heavy quark and its antiquark, which are in relative motion with respect to a hot and dense medium. The heavy quark-antiqua…
Naturalness, Vacuum Stability and Leptogenesis in the Minimal Seesaw Model
Gulab Bambhaniya, P. S. Bhupal Dev, Srubabati Goswami +2
The right-handed neutrinos within the type-I seesaw mechanism can induce large radiative corrections to the Higgs mass, and naturalness arguments can then be used to set limits on…
Phenomenological study of extended seesaw model for light sterile neutrino
Newton Nath, Monojit Ghosh, Srubabati Goswami +1
We study the zero textures of the Yukawa matrices in the minimal extended type-I seesaw (MES) model which can give rise to eV scale sterile neutrinos. In this model, three r…

We study embedding of non-commuting and , symmetries in discrete subgroups (DSG) of and analytically work out the mixing patterns implied by the assumpt…
Vector dark matter annihilation with internal bremsstrahlung
Gulab Bambhaniya, Jason Kumar, Danny Marfatia +2
We consider scenarios in which the annihilation of self-conjugate spin-1 dark matter to a Standard Model fermion-antifermion final state is chirality suppressed, but where this sup…

Frank F. Deppisch, Chandan Hati, Sudhanwa Patra +2
We consider the possibility of grand unification of the model in an SU(6) gauge unification group. Two possibilities arise. Unlik…

Tanmoy Modak, Jorge C. Romão, Soumya Sadhukhan +2
The rare decay has a very small rate in the Standard Model, due to a strong cancellation between the direct and indirect diagrams. Models with a changed co…

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…
