i study the DKP equation in presence of the Aharonov-Bohm effect and i see that the pauli criterion is changed and the commutation relation too. so, is there a relation between this result and the spin of the particle that we study ?
Definitly yes. If an ensemble of two linked particules with a spin in opposite direction is spinned, the spin of the particle in the opposite direction of the ensemble will change and take the direction of the ensemble. The two particules will have a spin in the same direction and will get inertia.
