Covariant generalization of the ISGW quark model


A fairly general Lorentz-covariant quark model of mesons is constructed. It has several versions whose nonrelativistic limit corresponds to the well-known Isgur, Scora, Grin-stein, and Wise model. In the heavy-quark limit, the covariant model naturally and automatically produces the heavy-quark symmetry results for meson decay constants and semileptonic… (More)
