Brief description

The XIV International Conference on Heavy Quarks and Leptons is dedicated to the study of the heavy quarks charm, bottom, and top with obvious extensions to interesting topics involving the strange quark. Neutrino oscillation studies and new insights in muon and tau lepton phenomenology are also included. The conference continues the tradition of regular scientific meetings, first started in 1993 at the Laboratori Nazionali di Frascati under the name "Heavy Quarks at Fixed Target", and widened in 2002 to include leptons with the workshop renamed to what is known as today.

The conference place in Yamagata during May is the best combination to enjoy the beautiful spring in Japan together with historical places, nature, foods and culture in a compact city.
