Probing the Internal Structure of $X(3872)$ via Magnetic Moment: Distinguishing Color-Singlet and Compact Configurations
The nature of the $X(3872)$ exotic hadron remains one of the most debated questions in hadron spectroscopy. We calculate its magnetic moment within a non-relativistic quark model that includes the three-body force arising from the cubic Casimir operator of $SU(3)_C$ with consistent dimensional analysis. Unlike previous...
