Abstract
This White Paper presents the community inputs and scientific conclusionsfrom the Hot and Cold QCD Town Meeting that took place September 23-25, 2022 atMIT, as part of the Nuclear Science Advisory Committee (NSAC) 2023 Long RangePlanning process. A total of 424 physicists registered for the meeting. Themeeting highlighted progress in Quantum Chromodynamics (QCD) nuclear physicssince the 2015 LRP (LRP15) and identified key questions and plausible paths toobtaining answers to those questions, defining priorities for our research overthe coming decade. In defining the priority of outstanding physicsopportunities for the future, both prospects for the short (~ 5 years) andlonger term (5-10 years and beyond) are identified together with thefacilities, personnel and other resources needed to maximize the discoverypotential and maintain United States leadership in QCD physics worldwide. ThisWhite Paper is organized as follows: In the Executive Summary, we detail theRecommendations and Initiatives that were presented and discussed at the TownMeeting, and their supporting rationales. Section 2 highlights major progressand accomplishments of the past seven years. It is followed, in Section 3, byan overview of the physics opportunities for the immediate future, and inrelation with the next QCD frontier: the EIC. Section 4 provides an overview ofthe physics motivations and goals associated with the EIC. Section 5 is devotedto the workforce development and support of diversity, equity and inclusion.This is followed by a dedicated section on computing in Section 6. Section 7describes the national need for nuclear data science and the relevance to QCDresearch.
