Solving the fermionic mass hierarchy of the standard model
Gauhar Abbas
We show that a simultaneous explanation for fermionic mass hierarchy among and within the fermionic families, quark-mixing, can be obtained in an extension of the standard model, w…
Flavour Model for Dirac Neutrinos: Type I and Inverse Seesaw
Debasish Borah, Biswajit Karmakar
We propose two different seesaw models namely, type I and inverse seesaw to realise light Dirac neutrinos within the framework of discrete flavour symmetry. The additional fi…
Electrical and thermal conductivities of hot and dense hadron gas
Guruprasad Kadam, Hiranmaya Mishra, Lata Thakur
We estimate the electrical and thermal conductivities of hot and dense hadronic matter in the relaxation time approximation of the Boltzmann equation. We estimate the thermodynamic…
Challenges posed by non-standard neutrino interactions in the determination of at DUNE
K. N. Deepthi, Srubabati Goswami, Newton Nath
One of the primary objectives of Deep Underground Neutrino Experiment (DUNE) is to discover the leptonic CP violation and to identify it's source. In this context, we study the imp…
Heavy quark complex potential in a strongly magnetized hot QGP medium
Balbeer Singh, Lata Thakur, Hiranmaya Mishra
We study the effect of a strong constant magnetic field, generated in relativistic heavy ion collisions, on the heavy quark complex potential. We work in the strong magnetic field…
Sub-MeV Self Interacting Dark Matter
Bhavesh Chauhan
In this paper, we present a model for sub-MeV dark matter with strong self interactions which can solve some of the small scale crisis of the CDM. The dark matter is a Majorana…
No-scale SUGRA Inflation and Type-I seesaw
Ila Garg, Subhendra Mohanty
We show that MSSM with three right handed neutrinos incorporating a renormalizable Type-I seesaw superpotential and no-scale SURGA Kähler potential can lead to a Starobinsky kind o…
Constraining slepton and chargino through compressed top squark search
Partha Konar, Tanmoy Mondal, Abhaya Kumar Swain
We examine the compressed mass spectrum with sub-TeV top squark () as lightest colored (s)particle in natural supersymmetry (SUSY). Such spectra are searched along with a…
Sensitivity to neutrino decay with atmospheric neutrinos at INO
Sandhya Choubey, Srubabati Goswami, Chandan Gupta +2
Sensitivity of the magnetised Iron CALorimeter (ICAL) detector at the proposed India-based Neutrino Observatory (INO) to invisible decay of the mass eigenstate using atmosphe…
Jet substructure shedding light on heavy Majorana neutrinos at the LHC
Arindam Das, Partha Konar, Arun Thalapillil
The existence of tiny neutrino masses and flavor mixings can be explained naturally in various seesaw models, many of which typically having additional Majorana type SM gauge singl…
Transport coefficients in Polyakov quark meson coupling model: a relaxation time approximation
Aman Abhishek, Hiranmaya Mishra, Sabyasachi Ghosh
We compute the transport coefficients, namely, the coefficients of shear and bulk viscosities as well as thermal conductivity for hot and dense matter. The calculations are perform…
Neutrino mass and the Higgs portal dark matter in the ESSFSM
Najimuddin Khan
We extend the standard model with three right-handed singlet neutrinos and a real singlet scalar. We impose two and -symmetries. We explain the tiny neutrino mass…
Supergravity Model of Inflation and Explaining IceCube HESE Data via PeV Dark Matter Decay
Girish Kumar Chakravarty, Najimuddin Khan, Subhendra Mohanty
We construct an unified model of inflation and PeV dark matter with an appropriate choice of no-scale Kähler potential, superpotential and gauge kinetic function in terms of MSSM f…
Inclusive spin-momentum analysis and new physics at a polarized electron-positron collider
B. Ananthanarayan, Saurabh D. Rindani
We consider the momentum distribution and the polarization of an inclusive heavy fermion in a process assumed to arise from standard-model (SM) -channel exchange of a virtual $γ…

Ila Garg, Srubabati Goswami, Vishnudath K. N. +1
We consider singlet extensions of the standard model, both in the fermion and the scalar sector, to account for the generation of neutrino mass at the TeV scale and the existence o…
Discrepancies in simultaneous explanation of Flavor Anomalies and IceCube PeV Events using Leptoquarks
Bhavesh Chauhan, Bharti Kindra, Ashish Narang
Leptoquarks have been suggested to solve a variety of discrepancies between the expected and observed phenomenon. In this paper, we show that the scalar doublet Leptoquark with Hyp…
Electromagnetic charge radius of the pion at high precision
B. Ananthanarayan, Irinel Caprini, Diganta Das
We present a determination of the pion charge radius from high precision data on the pion vector form factor from both timelike and spacelike regions, using a novel formalism based…
A model of spontaneous breaking at low scale

We introduce a symmetric model where masses of fermions are given by dimensional-5 operators, and is spontaneously broken at TeV scale. The unique feature of the model is…
