The 38th edition of the Winter Workshop on Nuclear Dynamics will be held February 5-11th, 2023 in the Marriott Puerto Vallarta Resort & Spa in Mexico. As with previous years, the workshop will bring together scientists from all fields of nuclear physics for engaging and friendly exchanges of ideas. Much emphasis will be on the recent LHC and RHIC heavy ion results, but advances in the ongoing and future programs at the EIC, FAIR, FRIB, and JLab will also be featured.
