Spectroscopy of atomlike mesons Qq-bar in a semirelativistic theory

Journal Article · · Phys. Rev. D; (United States)
; ;
A semirelativistic theory of an atomlike meson, a bound state of a heavy quark Q and a light antiquark q-bar, is developed on the basis of the equation introduced by Fermi and Yang in their composite model of a pion. As for the Qq-bar potential, a vector ''Coulomb'' plus scalar linear potential is chosen as an example and the transverse interaction of the gluon exchange is also taken into account. The spin-dependent forces are introduced automatically by applying the Foldy transformation to the heavy quark Q. Furthermore, the transverse gluon term generates additional spin-dependent forces. This model reproduces the mass levels of D (D/sup */), D/sub s/ (D/sub s//sup */), and B (B/sup */) mesons well. D/sup *//sup */(2420) is likely one of the 1/sup 1/P/sub 1/, 1/sup 3/P/sub 1/, or 1/sup 3/P/sub 2/ states.
