Flavor decomposition of electromagnetic multipole moments in $[q_1q_2][\bar q_3 \bar c]$ tetraquarks: Light-quark analogs of $T_{cs1}(2900)^0$ with $J^P = 1^+$

We present a systematic study of the magnetic dipole and electric quadrupole moments of compact $[q_1 q_2][\bar q_3 \bar c]$ tetraquark states with quantum numbers $J^P = 1^+$, in the diquark--antidiquark picture and within the light-cone QCD sum rule framework. By performing a flavor decomposition
