Contribution

It provides the first detailed calculation of magnetic dipole moments for specific light tensor mesons within the light cone QCD sum rules framework.

Findings

Charged tensor mesons have magnetic dipole moments significantly different from zero.

Neutral light tensor mesons have magnetic dipole moments close to zero.

Abstract

The magnetic dipole moments of the light tensor mesons $f_2$, $a_2$ and strange $K_2^{\ast 0} (1430)$ tensor meson are calculated in the framework of the light cone QCD sum rules. It is observed that the values of the magnetic dipole moment for the charged tensor particles are considerably different from zero. These values are very close to zero for the light neutral $f_2$ and $a_2$ tensor mesons, while it has a small nonzero value for the neutral strange $K_2^{\ast 0} (1430)$ tensor meson.
