Octet Baryon Masses and Magnetic Moments in Hot and Dense Isospin Asymmetric Nuclear Matter

Harpreet Singh, Arvind Kumar, Harleen Dahiya

Medium modification of the magnetic moments of octet baryons in the isospin asymmetric nuclear medium at finite temperature has been calculated using medium modified quark and bary…

Heavy vector and axial-vector $D$ mesons in hot magnetized asymmetric nuclear matter

Rajesh Kumar, Rahul Chhabra, Arvind Kumar

We observed the impact of finite magnetic field on the in-medium mass and decay constant of isospin averaged vector $D^{*} (D^{*^{+}}, D^{*^{0}})$ and axial-vector $D_{1} (D_{1}^{+}, D_{1}^{0})$ meso…

Upper bounds for the regularity of symbolic powers of certain classes of edge ideals

Arvind Kumar, S Selvaraja

Let $G$ be a finite simple graph and $I (G)$ denote the corresponding edge ideal in a polynomial ring over a field $K$ . In this paper, we obtain upper bounds for the Castel…

Charmonia and Bottomonia in asymmetric magnetized hot nuclear matter

Rajesh Kumar, Arvind Kumar

We investigate the mass-shift of $P$ -wave charmonium ( $I ¨ _{c}_{0}$ , $I ¨ _{c}_{1}$ ) and $S$ and $P$ -wave bottomonium ( $I^\cdot_{b}$ , $I^¥$ , $I ¨ _{b}_{0}$ and $I ¨ _{b}_{1}$ ) states in magnetized hot as…

Coprimality of Fourier coefficients of eigenforms

Satadal Ganguly, Arvind Kumar, Moni Kumari

Given a pair of distinct non-CM normalized eigenforms having integer Fourier coefficients $a_{1} (n)$ and $a_{2} (n)$ , we count positive integers $n$ with $(a_{1} (n), a_{2} (n)) = 1$ and make…
