Bottomonium states versus recent experimental observations in the QCD-inspired potential model

TL;DR

This paper models bottomonium states using a QCD-inspired potential, analyzing mass spectra and electromagnetic decays, and compares predictions with recent experimental data from Belle, BaBar, and LHC.

Contribution

It introduces a detailed potential model with relativistic corrections and quantifies the vector component of the confining potential, providing new predictions for bottomonium properties.

Findings

Vector component of confinement is anticonfining, constituting about 18.51% of the potential.

The model successfully reproduces known bottomonium energy levels.

Predictions for electromagnetic decay rates guide future experimental verification.

Abstract

In the QCD-inspired potential model where the quark-antiquark interaction consists of the usual one-gluon-exchange and the mixture of long-range scalar and vector linear confining potentials with the lowest order relativistic correction, we investigate the mass spectra and electromagnetic processes of a bottomonium system by using the Gaussian expansion method. It reveals that the vector component of the mixing confinement is anticonfining and takes around 18.51% of the confining potential. Combining the new experimental data released by Belle, BaBar and LHC, we systematically discuss the energy levels of the bottomonium states and make the predictions of the electromagnetic decays for further experiments.
