Non-self-conjugate mesons in a potential model with vacuum-polarization corrections

Journal Article · · Phys. Rev., D; (United States)
;
We present a unified approach to the study of non-self-conjugate mesons including both light and heavy mesons in the framework of the vacuum-polarization-corrected flavor-independent potential. We have found that the quark-confining potential in the form of an almost equal admixture of vector and scalar parts successfully explains the S-wave hyperfine levels of the observed light and heavy mesons. Finally we calculate the electromagnetic mass differences of the heavy-quark mesons and obtain (K-bar*/sup 0/-K*/sup -/)=3.79 MeV, (K-bar/sup 0/-K/sup -/)=6 MeV, (D*/sup +//sub c/-D*/sup 0//sub c/)=2.4 MeV, (D/sup +//sub c/-D/sup 0//sub c/)=5.8 MeV, (D*/sup 0//sub b/-D*/sup -//sub b/)=3.547 MeV, and (D/sup 0//sub b/-D/sup -//sub b/)=3.558 MeV.
