DESCRIPTION:Speakers: Dennis Perepelitsa (University of Colorado Boulder)\
 , Anthony Robert Timmins (University of Houston (US))\n\nThe Relativistic 
 Heavy-Ion Collider (RHIC) at BNL has played a central role in establishing
  the quark–gluon plasma (QGP) as a strongly coupled form of QCD matter\,
  that behaves collectively as a near-perfect liquid. Its major achievement
 s have transformed the field of nuclear physics and raised profound new qu
 estions in the study of QCD. These include how rapid thermalization can oc
 cur\, what is the microscopic mechanism of a strongly coupled QCD fluid\, 
 and the nature of the QCD phase transition.\nThe Large Hadron Collider (LH
 C) extends heavy-ion studies into a higher-energy regime characterized by 
 a hotter\, longer-lived medium\, with copious production of hard probes an
 d exotic hadrons/nuclei. These conditions have enabled unique opportunitie
 s for observables that are statistically limited or detector-constrained a
 t RHIC\, including high-energy jets\, heavy-flavor production over a broad
  momentum range\, precision quarkonia measurements\, and electroweak probe
 s. Such measurements play a key role in answering the aforementioned quest
 ions.\nAs the LHC heavy-ion program continues through the 2030s with upgra
 ded detectors and increased luminosity at the HL-LHC\, it will complement 
 the RHIC science program by extending precision studies of QCD matter to n
 ew kinematic regimes. Sustained U.S. participation enables the community t
 o maintain and build on expertise developed at RHIC and the LHC\, while c
 ontributing to detector operation\, upgrades\, and advanced analysis capab
 ilities required for discovery-level measurements of emergent QCD phenomen
 a.\nSuch activities are closely aligned with the major goals of the Electr
 on–Ion Collider (EIC)\, both in terms of studies of underlying QCD dynam
 ics and in sharing technologies for next-generation detectors. Insights in
 to the microscopic structure and collective behavior of strongly interacti
 ng QCD matter\, gained from heavy-ion and small-system studies at the LHC\
 , provide a key foundation for understanding the internal quark-gluon stru
 cture of protons and nuclei\, searches for gluon saturation\, and the dyna
 mics behind confinement.\nWith RHIC concluding operations this year\, this
  meeting aims to gather input from the U.S. QCD community to develop a vis
 ion that sustains our leadership in nuclear physics\, including completing
  the RHIC science mission\, ongoing contributions to the HL-LHC heavy-ion 
 program\, and the evolution of our field to support and advance EIC physic
 s. We will also discuss the huge potential we have to move forward with fe
 deral initiatives on Quantum Information Science (QIS) and Artificial Inte
 lligence (AI).\nThis meeting will be held at the APS Global Physics Summit
  in Denver\, Colorado - the largest physics research conference in the wor
 ld. The option to attend online is available.\nDennis Perepelitsa and Anth
 ony Timmins (co-chairs of the steering group)\n\nhttps://indico.cern.ch/ev
