14 March 2021

Dear Colleagues,

Welcome to the QWG meeting.   The Zoom instructions, sent by email on Friday, 12 March, are also available on the "Zoom and Gather.Town Guide" tab on this site.  The meeting password for both Zoom and Gather.Town was included in the email.  Please contact Vincent Cheung at the address provided in the welcome email with any technical difficulties.

Please also note that the local time zone is Pacific Daylight Time as of 14 March.

We ask speakers to please upload their slides on the Indico 12 hours ahead of their session so that the Zoom host can present the slides in case of technical difficulty.  Speakers can test screen share 10 minutes before their scheduled session begins.

At the end of each session, we invite you to join the breakout room in Gather.Town (link and instructions also to be provided in the email with meeting instructions) where you can chat with other participants.

We virtually welcome you to Davis and hope that you will have an opportunity to visit the area in person in the future.

best regards,

Ramona Vogt

on behalf of the Local Organizing Committee.

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. The workshop will start on Monday March 15, and close on Friday, March 19.  The schedule will be announced closer to the meeting.

We note that the QWG meeting will be followed by the virtual Quarkonia as Tools workshop and invite our participants to register for that meeting also.
