Heavy-light chiral quark model

Abstract: We present a new chiral quark model for mesons involving a heavy and a light (anti-) quark. The model relates various combinations of a quark -meson coupling constant and loop integrals to physical quantities. Then, some quantities may be predicted and some used as input. The extension from other similar models is that the present model includes the lowest order gluon condensate of the order (300 MeV) 4 determined by the mass splitting of the 0 − and the 1 − heavy meson states.Within the model, we find a reaso… Show more

“…At µ = Λ χ , which by construction is the matching scale within our approach [3,5,6], one finds a 1 ≃ −0.35 − 0.07i and a 2 ≃ 1.29 + 0.08i. Note that the Wilson coefficients a i are complex below µ = m c [8].…”
