Bounding effective parameters in the chiral Lagrangian for excited heavy mesons
We use recent experimental data on charmed mesons to constrain three coupling constants in the effective lagrangian describing the interactions of excited heavy-light mesons with light pseudoscalar mesons at order m Q . Predictions in the beauty sector are also derived. The coupling constants and the mass parameters in effective Lagrangians which reproduce QCD in specific limits represent impor...
متن کاملChiral Effective Theory for Heavy Mesons
I review recent developments in the description of the interactions between light and heavy mesons by an effective chiral lagrangian having the symmetries of the Heavy Quark Effective Theory. In particular the problem of the determination of the strong coupling constants gP Pπ and gP Pρ (P, P ∗ = heavy mesons) is addressed. BARI-TH/94-188 November 1994 Invited talk given at the 18th J. Hopkins ...
متن کاملStrong Decays of Excited Heavy Mesons In Chiral Perturbation Theory*
We construct an effective Lagrangian describing the interaction of soft pions and kaons with mesons containing a heavy quark and light degrees of freedom in an orbital p wave. The formalism is easily extended to heavy mesons and baryons in arbitrary excited states. We calculate the leading contributions to the strong decays D∗ 2 → Dπ, D∗ 2 → D∗π and D1 → D∗π. We confirm the relations between th...
متن کاملExcited Heavy Mesons and Kaon Loops in Chiral Perturbation Theory
We consider the-effects of excited states on the SU(3) breaking chiral loop corrections to heavy meson properties. In particular, we compare the size of kaon loops in which an excited heavy meson appears to the size of previously calculated loops with heavy mesons in the ground state. We find that the new effects may indeed be of the same magnitude as the old ones, but that there is a strong de...
متن کاملA chiral Lagrangian for excited pions
We construct a chiral Lagrangian containing besides the usual pion field (π) also its first radial excitation (π′). The Lagrangian is derived by bosonization of a Nambu– Jona-Lasinio quark model with separable non-local interactions, with form factors corresponding to 3–dimensional ground and excited state wave functions. Chiral symmetry breaking is governed by the NJL gap equation. The effecti...
