10:20 → 10:40 Introduction

Présidents de session: Carlos MUNOZ CAMACHO (IJCLab), Michael Winn (DPhN/IRFU/DRF/CEA Paris-Saclay)

10:20 Welcome from working group GT4: QCD and heavy-ion collisions

Orateurs: Carlos MUNOZ CAMACHO (IJCLab), Cyrille Marquet (CPHT - Ecole Polytechnique), Michael Winn (DPhN/IRFU/DRF/CEA Paris-Saclay)

10:30 French input to EPPSU: procedure and calendar

Orateurs: Herve Moutarde (CEA-IRFU-SPHN), Laurent Vacavant (IN2P3), Marcella Grasso (IN2P3)

10:40 → 11:30 HL-LHC programme in Run 5 and 6

10:40 LHCb upgrade II physics programme

11:05 ALICE 3 physics programme

11:30 → 11:55 Physics beyond colliders or other HL-LHC inputs

11:30 Open slot I

11:55 → 13:00 Lunch

13:00 → 13:45 Future colliders at CERN

13:00 FCCee with emphasis on QCD

13:25 Accelerator technologies with potential for QCD beyond the LHC

Very broad overview of technology status

• Energy Recovery LINAC: high-energy, high-intensity electron beam for fixed-target or collider
• Plasma-wave acceleration: very high-energy, low-intensity electron beam for fixed-target or collider
• High-field magnet: high-energy hadron beams fixed-target/collider with smaller synchrotrons than LHC and in view of FCC-hh

13:45 → 14:25 Discussions on HL-LHC and future colliders

13:45 Guided discussion on community inputs w.r.t. Run 5 and 6 programme, time-parallel activities and w.r.t. future colliders at CERN

Goal:
find factual statement w.r.t. community repartitions and consensus (or close-to) statements w.r.t. accelerator schedule and requirements in terms of human resources and investment already to be taken into account when writing inputs

14:25 → 14:50 Coffee break

14:50 → 16:15 Theory

14:50 Theory perspectives for QCD in heavy-ion collisions at the HL-LHC

Goal:
- requirements
- open questions in this field

15:10 Theory perspectives for hadron structure at the EIC and the HL-LHC

Goal:
- requirements
- open questions in this field

15:30 Theory perspectives for high-precision e⁺e⁻ programme

Goal:
- requirements
- open questions in this field

15:50 Discussion on theory requirements for future programmes

Goal:
Find factual statement w.r.t. community repartition and consensus (or close-to) statements w.r.t. interests and requirements in terms of human resources and investment already to be taken into account when writing inputs

16:15 → 16:55 Synergy and interdependence between CERN-based projects and other projects

16:15 Synergy between CERN projects and EIC: physics and technology

16:35 Discussion on synergy and interdependence between different accelerator-based activities

Goal:
find factual statement w.r.t. R&D interdependence and requirements in terms of human resources and investment already to be taken into account when writing inputs
