3. e+e- HZ physics constraints
Vertex detector:
c/t besides b
Light and small pixels
Tracker:
Fit Mrecoil from Zmm
Light and excellent resolution
Calorimeters:
Hgg  ECAL resolution
Hqq, VV  ECAL+HCAL resolution

5. e+e- options Can use ILC detectors as starting point
ILD (baseline of CepC pre-CDR)
Pixels, TPC, particle flow calorimeters
SiD
Pixels, Si microstrips, particle flow calorimeter
4° concept
Pixels, Drift Chamber, Dual Readout calorimeters , Dual Solenoid
Any of these works well on the Higgs
Additional requirements may be needed for Tera/Giga Z operation
Eg. Particle ID

6. ILD Large solenoid with calorimeters inside

7. SiD More compact with Si tracker Workshop RD_FA, Roma3, Novembre 2016

8. 4° concept Dual solenoid Workshop RD_FA, Roma3, Novembre 2016
F. Bedeschi, INFN-Pisa

9. Putting it all together
Can’t simulate everything!
e+e- proposal: ILD is baseline
Replace inner tracker with Si or DCH
Variations on pixel vertex detector
Particle flow vs. Dual Readout calorimetry
Muon system: yoke vs dual solenoid

10. INFERNO 100 TeV pp operation L ~ 2x1035  ~1000 overlapping events
Extreme radiation > 1017 neq/cm2 in frw region

11. 100 TeV pp operation H drives large acceptance and b tagging
BSM physics drives good momentum/energy resolution
Workshop RD_FA, Roma3, Novembre 2016

12. 100 TeV pp operation One baseline define for FCC-hh Inner tracker
Workshop RD_FA, Roma3, Novembre 2016
F. Bedeschi, INFN-Pisa

13. FCC hh Not much choice here... Take FCC baseline
Demonstrate you can do physics (eg. HHH)
Study radiation levels and demonstrate detector resistance

14. Muon collider Best option for high energy lepton collider Muons
Linear
Circular

15. Muon Collider Backgrounds are critical Fluence/crossing
Cones are 6 meters of Tungsten
1.5 TeV beam
1012 muons/bunch

16. Muon collider
Shielding optimization critical before any reasonable detector simulation
In particular inner detector region
Workshop RD_FA, Roma3, Novembre 2016
F. Bedeschi, INFN-Pisa

17. Summary e+e- straightforward but
Many variations of basic detector to consider
Should decide which ones to chose
hh has fewer options but much more complex simulations and anaysis
Should concentrate on few physics channels
mm backgrounds critical
Should concentrate on shielding optimization
