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…

Weak decays of Bc meson in a QCD potential model

K K Pathak, S Bhattacharya, T Das

The leptonic and semileptonic decay propertis of Bc mesons are studied in a QCD potential model. The CKM element for the leptonic decay is calculated by evaluating its decay consta…

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…

Charge radii of heavy flavored mesons in a potential model

T Das, D K Choudhury, K K Pathak +1

We report the results for charge radii of heavy flavored mesons ( $D^{+}, D^{0}, D_{s}^{+}, B^{+}, B^{0}, B_{s}^{0}$ ) in an improved QCD potential model. To enhance the effectiveness of short range…

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…
