The 33rd International Symposium on Lattice Field Theory (Lattice 2015) was held from July 14 to July 18, 2015 in Kobe Convention Center, Kobe, Japan. The annual lattice conferences in this series are most important for a community of theoretical and computational physics who have common interest in quantum field theories on the lattice. The scientific program contained 18 plenary session talks and 331 parallel session contributions including talks and posters. The conference topics included: algorithms and machines, applications beyond QCD, chiral symmetry, hadron spectroscopy and interactions, hadron structure, nonzero temperature and density, physics beyond the standard model, standard model parameters and renormalization, theoretical developments, vacuum structure and confinement, and weak decays and matrix elements. Over 376 participants attended the conference from 26 countries and regions in the world to exchange ideas and share new developments in the field.
We would like to thank the members of International Advisory Committee for their help in organizing the fruitful scientific program. Many thanks also go to all the speakers for making the conference successful. We also acknowledge financial support from Cray Inc., Fujitsu Limited, Hitachi, Ltd., NVIDIA Corporation, Kobe Convention and Visitors Association, and Tsutomu Nakauchi Foundation.
