Bayesian Inferences on Analytical Equations of State Approximations of Neutron Stars

Arijit Das, Sourav Roy Chowdhury

Equations of state (EoS) for dense matter are commonly provided in tabulated pressure-energy density relations, complicating numerical implementation and potentially compromising t…

Observables and conformal properties of dark matter admixed isentropic neutron stars

Arijit Das, Prashanth Jaikumar, Adarsh Karekkat +1

We construct an equation of state for isentropic dark-matter-admixed neutron stars (DMANS) with a hot core and relatively cold crust incorporating self-consistent temperature and D…

Fresh look at the LHC limits on vector leptoquarks

Arijit Das, Tanumoy Mandal, Subhadip Mitra +1

Vector leptoquarks (vLQs) are popular candidates for searching for physics beyond the Standard Model. In this paper, we present updated exclusion limits on various vLQ species, acc…

Effects of a Brueckner-Hartree-Fock-corrected effective mass on speed of sound, conformality, and observables of dark matter-admixed neutron stars

Arijit Das, Prashanth Jaikumar, Adarsh Karekkat +1

We construct an equation of state describing cold and dense matter in the core of neutron stars which includes an admixture of fermionic dark matter and incorporates nucleon effect…

TooLQit: Leptoquark Models and Limits

Arvind Bhaskar, Yash Chaurasia, Arijit Das +5

We introduce the leptoquark (LQ) toolkit, TooLQit, which includes leading-order FeynRules models for all types of LQs and a Python-based calculator, named CaLQ, to test if a set of…

Fresh look at the LHC limits on scalar leptoquarks

Arvind Bhaskar, Arijit Das, Tanumoy Mandal +2

The scalar-leptoquark (sLQ) parameter space is well explored experimentally. The direct pair production searches at the LHC have excluded light sLQs almost model agnostically, and…
