Effective 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 کاملExotic Mesons, Theory and Experiment *
In this talk I summarize the status of exotic mesons, including both theoretical expectations and experimental candidates. The current experimental candidates are " spin-parity exotics " ; since these are most often considered possible hybrid mesons, the theoretical discussion will be mainly concerned with hybrids. The exotic meson candidates discussed are the surprisingly light π 1 (1400) and ...
متن کاملChiral Theory of Mesons
A U(2)L×U(2)R chiral theory of pseudoscalar, vector, and axial-vector mesons has been proposed. VMD has been revealed from this theory. The physical processes of normal parity and abnormal parity have been studied by using the same lagrangian and the universality of coupling has been revealed. Two new mass relations between vector and axial-vector mesons have been found. Weinberg’s first sum ru...
متن کاملTheory of Cosmic-Ray Mesons
The quantum theory of damping developed by two of us (Heitler and Peng) is applied to the production of mesons by proton-proton collisions. For this purpose the modification of the meson theory proposed by Mpller and Rosenfeld is used. A primary radiation consisting of protons with a suitable energy spectrum is assumed, and it is shown that the rate of meson production is so high that nearly al...
متن کاملField distributions in heavy mesons and baryons
Field distributions generated by static Q ¯ Q and QQQ sources are calculated analytically in the framework of the Field Correlator Method (FCM) using Gaussian (bilocal) correlator. In both cases the string consists mostly of longitudinal color electric field, while transverse electric field contributes locally less then 3%, in agreement with earlier lattice studies. In the QQQ case the profile ...
