Inspired by the observation of the doubly charmed state Tcc and following theoretical studies on its spectroscopic parameters, we investigate its magnetic dipole moment, assigning it the quantum numbers JP=1+, and both the compact diquark-antidiquark and molecular structures in the framework of the light cone QCD. We also calculate the magnetic dipole moment of the theoretically predicted singly charmed state, ZV++, with two units of electric charge and the quantum numbers JP=1 in diquark-antidiquark picture. The numerical results are obtained as μTcc+Di=0.660.23+0.34μN, μTcc+Mol=0.430.22+0.23μN and μZV++=3.350.73+0.89μN. These results may be checked via other phenomenological approaches. The obtained results may be useful in exact determinations of the natures of these states.

Tcc+和ZV++四夸克态的磁偶极矩

灵感来自对双重魅力状态的观察 CC 在对其光谱参数进行理论研究之后,我们研究了它的磁偶极矩,并为其分配了量子数 J=1+,以及光锥 QCD 框架中的紧凑双夸克-反双夸克和分子结构。我们还计算了理论上预测的单魅态的磁偶极矩,Z++, 有两个电荷单位和量子数 J=1-在diquark-antidiquark图片中。数值结果为μCC+-D一世=0.66-0.23+0.34μN, μCC+-摩尔=0.43-0.22+0.23μNμZ++=3.35-0.73+0.89μN. 这些结果可以通过其他现象学方法进行检查。获得的结果可能有助于准确确定这些状态的性质。
