Generalized screened potential model

TL;DR

This paper introduces a non-relativistic quark model that includes screening effects from meson-meson configurations, leading to new predictions for the heavy quark meson spectrum, especially in bottomonium.

Contribution

The model uniquely incorporates screening effects into the interquark potential, providing a more accurate description of heavy meson spectra compared to traditional models.

Findings

Extra states predicted in bottomonium spectrum

Screening effects significantly alter meson energy levels

Model improves agreement with experimental data

Abstract

A new non relativistic quark model to calculate the spectrum of heavy quark mesons is developed. The model is based on an interquark potential interaction that implicitly incorporates screening effects from meson-meson configurations. An analysis of the bottomonium spectrum shows the appearance of extra states as compared to conventional non screened potential models.
