Abstract

Relativistic procedure of explicit accounting of the orbital momentum and spin of the \(V\) -meson resonance is suggested for the high energy inclusive reaction \(A+B\to V+X\to 1+2+X\) . It is compared decays of the structureless and composite \(V\) -mesons. Composite mesons are constructed within to the general field-theoretical approach, where hadrons and hadron-resonances are bound states of quarks. It is shown that structure of the meson generate an additional terms in the amplitude of the \(V\) -meson decay \(V\to 1+2\) and an additional dependence on the orbital momentum of this resonance. Special attention is given to the model-independent (kinematical) determination of the spin quantization axis of the \(V\) -meson resonance using angular distribution of particles 1 and 2 in \(V\to 1+2\) .
