New method for calculating quark model with unequal mass and higher angular momentum

A new calculation method, called complete Rotation Method, is proposed to research the quark models. With this method, the mesonic scalar-scalar and spinor-spinor quark models are generalized to the case where the mass of quark is not equal to that of the anti-quark. In order to maintain the covariance of Bethe-Salpeter equation, a four dimensional covariant potential for physical requirement. The quantitative results are in agreement with experiment, not only for the radius of pion but also for the spacelike electromagnetic form factor of pion. Other physical quantities are also calculated. The kernal functions of higher angular momentum are partly given. 10 references
