Interaction studies of a heavy - light meson - baryon system
We study time correlation functions of operators representing heavy-light K–Λ like systems at various relative distances r. The heavy quarks, one in each hadron, are treated as static. An anisotropic and asymmetric lattice is used with Wilson fermions. Our goal is to extract an adia-batic potential and thus learn about the physics of the five-quark system viewed as an hadronic molecule.
متن کاملLight meson spectra and instanton-induced forces
The spinless Salpeter equation supplemented by an instanton-induced force is used to describe the spectra of light mesons, including the pseudoscalar ones. The coupling constants of the instanton-induced potential, as well as the quark constituent masses, are not treated as simple free parameters but are calculated from the underlying instanton theory. Quite good results are obtained provided t...
متن کاملmeson and the light - heavy quarkonium spectrum
We compute the c ¯ b spectrum from a first principle Salpeter equation obtained in a preceding paper. For comparison we report also the heavy-light quarko-nium spectrum and the hyperfine separations previously presented only in a graphical form. Notice that all results are parameter free. The spectrum and properties of the c ¯ b systems have been calculated various times in the past in the fram...
متن کاملA Constituent Quark-Meson Model for Heavy-Meson Processes
We describe the effective heavy meson lagrangian for Sand P-wave heavy-light mesons in terms of a model based on meson-quark interactions, where mesonic transition amplitudes are represented by diagrams with heavy mesons attached to loops containing heavy and light constituent quarks. The model is relativistic and incorporates the heavy quark symmetries. The universal form factors of the heavy ...
متن کاملA Constituent Quark-Meson Model for Heavy Meson Decays
I describe a model for heavy meson decays based on an effective quark-meson lagrangian. I consider the heavy mesons S with spin and parity J = (1, 0), H with J = (1, 0) and T μ with J = (2, 1), i.e. S and P wave heavy-light mesons. The model is constrained by the known symmetries of QCD in the mQ → ∞ for the heavy quarks and chiral symmetry in the light quark sector. Using a very limited number...
