The XVII International Conference on Heavy Quarks and Leptons (HQL 2025) was held at Peking University, Beijing, China during September 15-19, 2025.
The Heavy Quarks and Leptons conference series is dedicated to the study of heavy quarks, namely charm, bottom, and top, with possible extensions to interesting topics involving the strange quark. Neutrino oscillation studies as well as new insights into the muon and tau lepton sectors are also included. It 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 being renamed to its current form.
This marks the hosting of the HQL Conference in China for the first time. We sincerely hope all participants will not only engage in fruitful academic exchanges, but also immerse themselves in the profound richness of Chinese culture during this gathering.
