Hyperfine Structure of $B$ and $D$ Mesons in a QCD-Inspired Potential Model

Krishna Kingkar Pathak

We investigate the hyperfine structure of $B$ and $D$ mesons within a QCD-inspired potential model based on the Cornell ansatz. The conventional contact spin--spin term is regulari…

Universal Response Functions in Driven Dissipative Tunneling Dynamics

Krishna Kingkar Pathak

Universality in nonlinear nonequilibrium systems is typically expressed through scaling laws that render macroscopic behavior insensitive to microscopic details. Whether this unive…

Parameterisation space for Cornell potential in a QCD potential model

Krishna Kingkar Pathak, Satyadeep Bhattacharya, Tapashi Das

We make a critical analysis on the free parameters of the Cornell potential $- 4 α_{s} /3 r + b r + c$ and provide a parameterisation space for the strong coupling constant $α_{s}$ and the…

Isgur-Wise function and a new approach to Potential Model

Tapashi Das, D. K. Choudhury, K. K. Pathak

Considering the Cornell potential $V (r) = - \frac{4 α _{s}}{3 r} + b r + c$ , we have revisited the Dalgarno's method of perturbation by incorporating two scales $r^{s h or t}$ and $r^{l o n g}$ as in…

RMS and charge radii in a potential model

Tapashi Das, D. K. Choudhury, K. K. Pathak

The Dalgarno's method of perturbation is used to solve the Schrodinger's equation with the Cornell potential $V (r) = - \frac{4 α _{s}}{3 r} + b r + c$ . The short range and long range effect of…

Semileptonic decay of $B_{c}$ meson into $c c ˉ$ states in a QCD potential model

Krishna Kingkar Pathak, D K Choudhury

The slope and curvature of Isgur Wise function for $B_{c}$ meson is computed in a QCD potential model in two different approaches of choosing the perturbative term of the Cornell p…

Oscillation frequency of B and B mesons in a QCD potential model with relativistic effect

K K Pathak, D K Choudhury

Wavefunction at the origin with the incorporation of relativistic effect leads to singularity in a specific potential model. To regularise the wavefunction, we introduce a short di…

Isgur-Wise function in a QCD potential model with coulombic potential as perturbation

Bhaskar Jyoti Hazarika, Krishna Kingkar Pathak, D K Choudhury

We study heavy light mesons in a QCD inspired quark model with the Cornell potential $- \frac{4 α _{S}}{3 r} + b r + c$ . Here we consider the linear term $b r$ as the parent and $-\frac{4α_{S…
