Calculation of mass and width of unstable molecular state using the developed Bethe-Salpeter theory

Applying the developed Bethe-Salpeter theory for dealing with resonance, we investigate the time evolution of molecular state composed of two vector mesons as determined by the total Hamiltonian. Then exotic meson resonance \(\chi_{c0}(3915)\) is considered as a mixed state of two unstable molecular...
