光锥QCD求和规则中轻张量介子的磁偶极矩

Magnetic dipole moment of the light tensor mesons in light cone QCD sum rules

T. M. Aliev, K. Azizi, M. Savcı

摘要:

在光锥QCD求和规则框架下计算了轻张量介子$f_2$、$a_2$和奇异$K_2^{\ast 0} (1430)$张量介子的磁偶极矩。观察到带电张量粒子的磁偶极矩值与零有很大的不同。对于轻中性的$f_2$和$a_2$张量介子,这些值非常接近于零,而对于中性的奇异的$K_2^{\ast 0} (1430)$张量介子,它有一个小的非零值。

英文摘要:

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.
