( q q ¯ ) -pion mass and decay constant in a relativistic independent-quark model

Abstract: The mass and decay constant of the ðq" qÞ-pion together with the masses of r and u mesons are calculated in a chiral symmetric potential model of independent quarks, taking into account the corrections due to the possible residual interactions, such as quark-pion coupling arising out of the requirement of chiral symmetry and quark gluon coupling arising out of one-gluon-exchange, and that due to the spurious center-of-mass motion of the meson core. The effective potential representing phenomenologically the no… Show more
