Strong decays allowed by the Okubo-Zweig-Iizuka rule play a decisive role in determining the properties of particles. The widely used 3P0 model is non-relativistic and contains unknown adjustable parameter γ that need to be determined experimentally. Based on the Bethe-Salpeter equation, we have derived a relativistic calculation formula without additional parameters similar to γ. Using this method, we present the total width of hc(2P) and theoretically determine the value of the parameter γ in the 3P0 model.
