Lattice 2012, the 30th International Symposium on Lattice Field Theory
was held in Cairns, Australia from Sunday the 24th of June to Friday
the 29th June 2012. It was held at the Cairns Convention Centre,
providing world-class facilities in a beautiful location. Fine
weather and easy access to world heritage attractions including the
Great Barrier Reef and the Wet Tropics Rainforests made for an
extraordinary experience.
The conference was organised by the Special Research Centre for the Subatomic Structure of Matter (CSSM) in the School of Chemistry & Physics at the University of Adelaide.
More than 285 participants from around the world attended the symposium. The scientific program contained 22 plenary talks and 248 parallel contributions including posters. Most of these are recorded in this proceedings.
For 30 years, the Lattice meeting has provided researchers from around the world with an annual forum at which to disseminate and discuss ideas, developments and opportunities in the study of relativistic quantum fields regulated on a spacetime lattice. It fosters the exchange of ideas, networking, and builds relationships between researchers that are essential in facilitating rapid progress and the creation of new knowledge.
The program included plenary talks, parallel talks and poster presentations on Algorithms and machines, Applications beyond QCD, Chiral symmetry, Hadron spectroscopy and interactions, Hadron structure, Nonzero temperature and density, Standard model parameters and renormalization, Theoretical developments, Vacuum structure and confinement and Weak decays and matrix elements.
The International Advisory Committee provided excellent guidance in planning the scientific program of the conference and we thank the Committee for their important contributions. Thanks also to our presenters for the time and effort they put into preparing their talks and their proceedings.
Many thanks to our Conference Secretariat, Sharon Johnson, Silvana Santucci, Jeanette Roulston and Ramona Adorjan, who made our conference run perfectly. The contributions of Ben Menadue and Ben Owen in crafting this year's web presence and establishing our on-line payment and conference management interface to RegOnline are most gratefully received. Thanks to James Zanotti for his enormous efforts in organising the conference program and to Hrayr Matevosyan for his creation of the Lattice 2012 Conference logo.
Financial support for Lattice 2012 is gratefully acknowledged. Our
sponsors include the ARC Centre of Excellence for Particle Physics at
the Terascale (CoEPP)
Finally, we thank the conference delegates who made the long journey to Australia and made the conference a resounding success.
