Dark energy?
Things we don’t know about yet?

7. Goals @(HL-)LHC Explore limits of Standard Model
Precision probe of Higgs, top quark and boson behaviour (ATLAS, CMS)
Precision probe of antimatter behaviour (LHCb)
Probe quark-gluon plasma (ALICE)
Search for New Physics
Directly through discovery of new particles (ATLAS, CMS)
Indirectly through strange behaviour of known particles (LHCb)

11. UK@HL-LHC Accelerator upgrades
Crab cavities, beam collimation, diagnostic systems, cold powering cables
Necessary to achieve increased performance of HL-LHC
LHC

12. UK@HL-LHC Silicon tracker systems LHCb, ATLAS, ALICE
Necessary to determine particle trajectories
Need to cope with increased radiation levels and higher luminosity.
Prototype LHCb detector
Prototype ATLAS detectors

13. UK@HL-LHC Trigger and fast electronics CMS, ATLAS, ALICE
Prototype ALICE trigger unit
Trigger and fast electronics
CMS, ATLAS, ALICE
Necessary to recognise and select potential discoveries in real time:
Radiation tolerant ASICs
High data throughput: FPGAs, fibre optic links.
ASIC application specific integrated circuit
Field programmable gate array
Prototype CMS trigger processor

14. UK@HL-LHC Computing and software experiments, GridPP
Necessary to analyse vast datasets produced by LHC:
3000 fb-1 (10x dataset) by 2030
Pileup ~ 150 for ATLAS, CMS
CERN computing centre

15. Conclusions Fascinating programme ahead.
(HL-)LHC is our premier particle physics facility
operating at the edge of technology
to discover the extremes of physics
Who knows what we’ll find …......
