Open Flavour Charmed Mesons in a QCD Potential model

TL;DR

This paper models open flavour charm mesons using a modified wavefunction in a QCD potential framework, estimating their masses, decay constants, decay widths, and lifetimes, with results aligning well with experimental data.

Contribution

It introduces a modified mesonic wavefunction with a short distance scale to improve predictions of charm meson properties within a QCD potential model.

Findings

Masses and decay constants match experimental values

Leptonic decay widths and lifetimes are accurately estimated

Model shows good agreement with existing theoretical results

Abstract

We modify the mesonic wavefunction by using a short distance scale r0 in analogy with Hydrogen atom and estimate the values of masses and decay constants of the open flavour charm mesons D, Ds and Bc within the framework of a QCD Potential Model. We also calculate leptonic decay widths of these mesons to study branching ratios and life time. The results are in good agreement with experimental and other theoretical values.
