ATLAS at HL-LHC Monica D Onofrio, Sara Alderweireldt, Steve McMahon, Pedro Teixeira-Dias, Sarah Williams
ATLAS in UK: from run 3 to HL-LHC ATLAS UK composition 14 universities + STFC Rutherford Lab 11.7% of ATLAS active authors 260 Physicists and 108 engineer/tech/admin 142 current doctoral students Project Funding: mainly from STFC Additional funding: EPSRC, UKRI, Royal Society, ERC, Marie Curie, Schmidt Family Foundation, Leverhulme Trust Run 4: UK Phase II upgrade responsibilities Major roles and international leaderships Just since 2021: 14 Level-1 coordinators, 15 Physics and Combined Performance group conveners (and >40 sub-group conveners) in diverse areas, ~55 Level-3 coordinators; ITk-Pixels ITk-Strips Calorimeter Trigger (eFEX & Global) High Level Triggering & DAQ Upgrade software dynamic community, engaged in developing new ideas at all levels, including ECRs and students ~ 650 students awarded PhD since 2005 Upgrade funding so far: 128M for 12 years (2014-2026)
Scientific deliverables Key physics deliverables (stub): - Precision measurements of SM parameters including W and top mass, sin theta_eff, B-Physics, top physics and more - Precision measurements of the Higgs boson couplings and evidence / observation of di-Higgs - Direct exploration of hundreds of new physics scenarios (supersymmetry, new resonances, dark sectors, dark matter searches) - Indirect constraints of new physics through precision measurements EWKS and Higgs-self coupling evidence (at least) BSM searches At least a factor of 2 expected in precision for W mass
Some additional parameters and costs centre-of-mass energy: 14 TeV integrated luminosity: 3000/fb number of interaction points: 1 (this is ATLAS) time running at stage: 10 years wall power to be checked accelerator length: 27 km estimated year for first collisions: 2030 future upgrade paths: 2033+ (LS5 and/or LS6) Environmental cost of construction (in units of tonnes of CO2 equivalent) - check if available Environmental cost of operation per year (in units of tonnes of CO2 equivalent) - check if available Estimate of financial costs (provide separate numbers for R+D phase, construction phase and operations phase) - Does your project plan dedicated submission(s) for the ESPPU (if so, give details) - HL-LHC is already the highest priority according to the European Strategy, a submission is being prepared by the international collaboration (actually, there are more than one submission being prepared)
