    Description
    The 17th edition of the QWG workshop will take place at CERN (Main Auditorium) from Nov 17th to 21th 2025. The QWG workshop is the premier opportunity for experimentalists and theorists to gather to discuss topics related to quarkonium physics. The scientific program will include topics related to heavy quarkonium in particle and nuclear physics as well as those in related fields.

    Speakers are by invitation only. There is no conference fee and participation in the workshop is free of charge.
