Hyperfine Structure of and Mesons in a QCD-Inspired Potential Model
Krishna Kingkar Pathak
We investigate the hyperfine structure of and mesons within a QCD-inspired potential model based on the Cornell ansatz. The conventional contact spin--spin term is regulari…
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 and provide a parameterisation space for the strong coupling constant and the…
Isgur-Wise function and a new approach to Potential Model
Tapashi Das, D. K. Choudhury, K. K. Pathak
Considering the Cornell potential , we have revisited the Dalgarno's method of perturbation by incorporating two scales and 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 . The short range and long range effect of…
Semileptonic decay of meson into states in a QCD potential model
Krishna Kingkar Pathak, D K Choudhury
The slope and curvature of Isgur Wise function for 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. Here we consider the linear term as the parent and $-\frac{4α_{S…
