distributions in Standard Model at large recoil
Diganta Das, Bharti Kindra, Girish Kumar +1
We study the rare decay in the Standard Model and beyond. Working in the transversity basis, we exploit the relations between the heavy-to…
Spin Polarization and Chiral Condensation in 2+1 flavor Nambu-Jona-Lasinio model at finite temperature and baryon chemical potential
Aman Abhishek, Arpan Das, Hiranmaya Mishra +1
We investigate the ferromagnetic (spin polarization) condensation in (2+1) flavor Nambu Jona-Lasinio(NJL) model with non-zero current quark masses at finite temperature and density…
Probing new physics in semileptonic decays
Atasi Ray, Suchismita Sahoo, Rukmani Mohanta
In recent times, several hints of lepton non-universality have been observed in semileptonic meson decays, both in the charged-current () and neutral-curren…
Heavy quark diffusion in a Polyakov loop plasma
Balbeer Singh, Aman Abhishek, Santosh K Das +1
We calculate the transport coefficients, drag and momentum diffusion, of a heavy quark in a thermalized plasma of light quarks in the background of Polyakov loop. Quark thermal mas…
Leptoquark solution for both the flavor and ANITA anomalies
Bhavesh Chauhan, Subhendra Mohanty
The ANITA experiment has seen anomalous Earth emergent showers of EeV energies which cannot be explained with Standard Model interactions. In addition, tests of lepton flavor unive…
Anatomy of Heavy Gauge Bosons in a Left-Right Supersymmetric Model
Biplob Bhattacherjee, Najimuddin Khan, Ayon Patra
We perform a detailed study of the various decay channels of the heavy charged and neutral gauge bosons ( and respectively) in a left-right supersymmetric (LRSUSY) frame…
Collider signature of Leptoquark with flavour observables
Aritra Biswas, Avirup Shaw, Abhaya Kumar Swain
The Leptoquark model has been instrumental in explaining the observed lepton flavour universality violating charged () and neutral () current anomalies that have be…
Probing vorticity in heavy ion collision with dilepton production
Jitesh R Bhatt, Hiranmaya Mishra, Balbeer Singh
We study the effect of vorticity present in heavy ion collisions (HICs) on the temperature evolution of hot quark-gluon plasma in the presence of spin-vorticity coupling. The initi…
Why the angular distribution of the top decay lepton is unchanged by anomalous coupling
Rohini M. Godbole, Michael E. Peskin, Saurabh D. Rindani +1
We give a simple physical argument to understand the observation that the angular distribution of the top decay lepton depends only on the polarisation of the top and is independen…
Chiral symmetry breaking, color superconductivity, and the equation of state for magnetized strange quark matter
Aman Abhishek, Hiranmaya Mishra
We investigate the vacuum structure of dense quark matter in strong magnetic fields at finite temperature and densities in a 3 flavor Nambu Jona Lasinio (NJL) model including the K…
Constraining minimal Type-III Seesaw Model from naturalness, Lepton Flavor Violation and Electroweak Vacuum stability
Srubabati Goswami, Vishnudath K. N., Najimuddin Khan
We study the minimal type-III seesaw model in which we extend the SM by adding two triplet fermions with zero hypercharge to explain the origin of the non-zero neutrino m…
Exploring dark matter, neutrino mass and anomalies in model
Shivaramakrishna Singirala, Suchismita Sahoo, Rukmani Mohanta
We investigate Majorana dark matter in a new variant of gauge extension of Standard Model, where the scalar sector is enriched with an inert doublet and a $(\bar{3…
Signature of light sterile neutrinos at IceCube
Bhavesh Chauhan, Subhendra Mohanty
The MiniBooNe collaboration has recently reported evidence for a light sterile neutrino with large mixing angles thus corroborating the measurement by LSND twenty years ago. Such a…
Thermoelectric effect and Seebeck coefficient for hot and dense hadronic matter
Jitesh R. Bhatt, Arpan Das, Hiranmaya Mishra
We investigate the thermoelectric effect for baryon rich plasma produced in heavy ion collision experiments. We estimate the associated Seebeck coefficient for the hadronic matter.…
Cutoff of IceCube Neutrino Spectrum due to t-channel Resonant Absorption by CB
Subhendra Mohanty, Ashish Narang, Soumya Sadhukhan
The non-observation of neutrinos by the IceCube at the Glashow resonance energy of 6.3 PeV has been a long standing unresolved issue. In this paper we propose a t-channel neutrino…
Confronting nuclear equation of state in the presence of dark matter using GW170817 observation in relativistic mean field theory approach
Arpan Das, Tuhin Malik, Alekha C. Nayak
We confront admixture of dark matter inside neutron star using gravitational wave constraints coming from binary neutron star merger. We consider a relativistic mean field model in…
Linear Seesaw for Dirac Neutrinos with Flavour Symmetry
Debasish Borah, Biswajit Karmakar
We propose a linear seesaw model to realise light Dirac neutrinos within the framework of discrete flavour symmetry. The additional fields and their transformations under the…
Dark side of the Seesaw
Subhaditya Bhattacharya, Ivo de Medeiros Varzielas, Biswajit Karmakar +2
In an attempt to unfold (if any) a possible connection between two apparently uncorrelated sectors, namely neutrino and dark matter, we consider the type-I seesaw and a fermion sin…
Common Origin of Dirac Neutrino Mass and Freeze-in Massive Particle Dark Matter
Debasish Borah, Biswajit Karmakar, Dibyendu Nanda
Motivated by the fact that the origin of tiny Dirac neutrino masses via the standard model Higgs field and non-thermal dark matter populating the Universe via freeze-in mechanism r…

Kumar Rao, Saurabh Rindani
We show how the boson polarization in the process of associated production at the Large Hadron Collider (LHC) can be used to constrain anomalous couplings. We…
