TL;DR

This paper calculates the magnetic dipole moments of negative parity $J^{PC}=2^{--}$ tensor mesons using light cone QCD sum rules, revealing parity-dependent differences in their magnetic properties.

Contribution

It provides the first detailed comparison of magnetic dipole moments between negative and positive parity tensor mesons within the QCD sum rules framework.

Findings

Negative parity light mesons have smaller magnetic dipole moments than positive parity ones.

Negative parity heavy mesons exhibit larger magnetic dipole moments compared to positive parity counterparts.

Results enhance understanding of parity effects on meson electromagnetic properties.

Abstract

Magnetic dipole moments of the negative parity light and heavy tensor mesons are calculated within the light cone QCD sum rules method. The results are compared with the positive parity counterparts of the corresponding tensor mesons. The results of the analysis show that the magnetic dipole moments of the negative parity light mesons are smaller compared to those of the positive parity mesons. Contrary to the light meson case, magnetic dipole moments of the negative parity heavy mesons are larger than the ones for the positive parity mesons.
