# Masses of Heavy-Light mesons with two loop static potential in a Variational approach

## TL;DR

This paper calculates heavy-light meson masses using a variational method with a two-loop static potential, showing improved accuracy over traditional perturbation techniques in the heavy-flavored meson sector.

## Contribution

It introduces a variational approach incorporating two-loop effects in the static Cornell potential for meson mass calculations, outperforming existing methods.

## Key findings

- Variational method yields more accurate meson masses.
- Gaussian wave-function provides better results than Coulomb.
- Approach is more successful than stationary state perturbation theory.

## Abstract

In this work, we investigate the masses of a few heavy-light mesons with variational method, taking into account the two-loop effects in the static Cornell potential. Specifically, we consider two wave-function,Gaussian and Coulomb. Our analysis suggests that phenomenologically such approach is more successful in the Heavy flavoured meson sector than the stationary state perturbation theory and other approximation methods.
