چکیده

The current status of lattice calculation of weak matrix elements for heavy quark systems is reviewed. After an assessment of systematic errors in present simulations, results for the B meson decay constant, the B parameter BB and semi-leptonic heavy-to-light and heavy-to-heavy transitions are discussed. The final topic are lattice results for heavy baryon spectroscopy.

News from Lattice QCD on Heavy Quark Potentials and Spectral Functions of Heavy Quark States

We discuss recent lattice results on in-medium properties of hadrons and focus on thermal properties of heavy quark bound states. We will clarify the relation between heavy quark free energies and potentials used to analyze the melting of heavy quark bound states. Furthermore, we present calculations of meson spectral functions which indicate that the charmonium ground states, J/ψ and ηc, persi...

Modeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions

By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...

Status of heavy quark physics from the lattice

Lattice simulations provide a powerful tool to study QCD beyond perturbation theory. In particular, for quark masses around or below that of the strange quark, today’s lattices offer the possibility of very accurate and direct calculations of hadronic observables. The recent feasibility of simulating dynamical fermions (i.e. without neglecting the effects of internal quark loops) provide a sign...
