Flavor physics is entering an exciting era. The accumulation of data has stimulated abundant theoretical studies of flavor dynamics within and beyond the standard model. Experiments have confirmed the patten of quark flavor mixing, the mixing of different flavors of neutrinos, and that neutrinos have nonzero masses. However, the origin of quark and lepton masses and of  their mixing is still not understood. The two running B-factories, BaBar and Belle, have made precision measurement of B-meson decays possible, and cast a challenge to current models of heavy-flavor dynamics. Tevatron has provided useful information on formation of heavy-flavor hadrons and their decays. Many new excited and ”exotic” hadronic states with open or close charm are discovered by BaBar, Belle and CLEO. Besides the operating colliders, those facilities under construction and upgrade, such as LHC, BEPC2 with BES3, and DaYa Bay neutrino
project, or in planing, such as Super B-factories, will provide more decisive information to the important subjects in flavor physics.

Motivated by the above experimental and theoretical progresses, we propose a KITPCprogram with the title ”Advanced Topics on Flavor Physics”, which aims at a more advanced understanding of flavor dynamics. The program will be held at KITP in China. Active international and domestic researchers in this field will be invited to station at KITPC for some time, so that they can exchange expertise and have discussions intensively, through which collaborations at different scales and levels on interesting projects will be stimulated. It is worthwhile to mention that there is a large fraction of particle physicists in China (including Taiwan) working on flavor physics. The proposal, if approved, will strengthen the interaction among the researchers within and outside this region, and benefit both the particle-physics communities across the strait.
