Chiral 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.

متن کاملEffective Field Theory of Heavy Mesons
In this paper we present a detailed formulation for a recently proposed effective field theory to describe the nonperturbative QCD dynamics of heavy mesons. This effective theory incorporates with heavy quark symmetry (HQS) and the heavy quark effective theory (HQET). Heavy mesons in this theory are constructed as composite particles of a heavy quark bounded with the light degrees of freedom. T...
متن کاملTheory of Semi– and Nonleptonic Decays of Heavy Mesons
I review some of the recent developments in the theoretical description of weak inclusive decays of heavy mesons. The topics cover the value of |Vcb| as extracted from semileptonic inclusive decays and a short discussion of the theoretical errors. I also present the results of a recent calculation of next–to–leading order corrections to nonleptonic inclusive B decays which allows an improved pr...
متن کاملOn the Theory of Hyperons and Heavy Mesons
During the past few years there haa accumulated so much experimental information on hyperons and heavy mesons that some of the many puzzling questions on these strange particles arebeing resolved. Under such circumstances one is often motivated to seek for an ordering principle by which one can understand why there are such particles as being known, why they are of such nature as being observed...
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...
