Abstract In this report we review the latest results on heavy quark physics reached at HERA by the H1 and ZEUS collaborations. We start from the open charm measurements performed both in photoproduction and in deep inelastic scattering regime following with bound charm physics.

Strong CP in Heavy Quark Physics
Communications in Theoretical Physics, 1991We argue that strong CP phase should be shifted to b and t quark masses due to the requirement of vacuum stability. The strong CP problem in low energy sector thus disappears. We predict large CP violation in electric dipole moment of W and heavy quarks.

Heavy Quark Physics on Large Lattices
2005We describe our recently initiated project for the non-perturbative study of heavy quark systems in quenched lattice QCD. Motivated by the desire to avoid additional approximations, we work on fine lattices which are large in terms of the number of lattice points.

Heavy Quark Physics from Lattice NRQCD
International Journal of Modern Physics A, 1997I discuss recent lattice calculations of the spectroscopy of mesons containing only b and c quarks using the Non-Relativistic QCD (NRQCD) action for heavy quarks. I discuss the benefits of using a non-relativistic effective action in heavy quark calculations and the manner in which heavy quark systems are insensitive to the systematic errors common in

1997
Heavy Quark Effective Theory (HQET) is reviewed and applied to extracting the fundamental parameters of the Standard Model from experimental data. The main focus is on precision measurements of the Cabibbo-Kobayashi-Maskawa matrix element |Vcb|, and the charm and bottom quark masses mc and mb.
