ar X iv : h ep - l at / 0 01 10 13 v 1 1 N ov 2 00 0 1 Chemical potential response of heavy light meson mass

We study the response of the heavy-light meson mass to the chemical potential (∂m/∂µ) at high temperature and at zero chemical potential. Preliminary results show that ∂m/∂µ|µ=0 is negative in the confinement phase and is positive in the deconfinement phase. This may suggest the possibility for the suppression of J/ψ without the quark gluon plasma formation.

We study the response of meson masses to the chemical potential (∂m/∂µ) at high temperature and at zero chemical potential on N f = 2 lattice with staggered fermions. Preliminary results for the meson composed of different quarks show that ∂m/∂µ|µ=0 is negative in the confinement phase and positive in the deconfinement phase.

The heavy-quark expansion for inclusive semi-leptonic B decays introduces Λ̄ and λ1, which are matrix elements in heavy-quark effective field theory. We review how they can be obtained from an analysis of the heavy quark mass dependence of heavy-light meson masses in lattice QCD. We present preliminary results for the bottom quark mass, mb, using Λ̄ and λ1 for the Bs meson from a 2+1 sea-flavor u...

A system of two static quarks, at fixed distances r, and two light quarks is studied on an anisotropic lattice. Excitations by operators emphasizing quark or gluon degrees of freedom are examined. The maximum entropy method is applied in the spectral analysis. These simulations ultimately aim at learning about mechanisms of hadronic interaction.

After a brief discussion of the promise and limitations of the lattice technique, I review lattice QCD results for several quantities of phenomenological interest. These are: matrix elements for heavy-to-light meson decays, leptonic decay constants f B and f D , the parameters B B and B K for neutral B and K meson mixing respectively, the strong coupling constant, light quark masses and the lig...
