u Additional comment in the European Strategy statement J
“The FCC-ee / FCC-hh combination offers, for a great cost effectiveness, the best precision and the best search reach on the market”, see JHEP01(2014)164
TLEP/FCC-ee : Physics case
FCC Break-Out session (14-Feb-2014)
Lepton Collider: Physics, Experiments, Detectors 6
= 2×104 LEP, 1000 ILC
= 5×106 LEP, 100 ILC
= 5000 LEP (for W pairs), 35 ILC (for HZ)
= 7 ILC
Highest achievable energy to be determined (400-500 GeV?)
Patrick Janot
TLEP/FCC-ee : Physics case Examples of what unequalled precision buys at FCC-ee:
u Sensitivity to weakly-coupled new physics up to 30 TeV (via Z, W, top properties)
l Complementary to FCC-hh: direct sensitivity to coloured new physics up to 30 TeV
u Sensitivity to new physics coupled to the Higgs sector up to 5-10 TeV
l Via measurements of Higgs couplings and width down to 0.1% precision
u Sensitivity to other new physics through rare decays (Z, W, H, t, b, c, t, …)
u Sensitivity to the (heavy, sterile) neutrino sector through invisible decays
u Direct searches for rare processes

TLEP/FCC-ee Design Study: Timeline
From Michael’s Benedikt presentation
u We are here at “Phase 0” (Preparation)
FCC Break-Out session (14-Feb-2014)
Lepton Collider: Physics, Experiments, Detectors 12
Patrick Janot
TLEP/FCC-ee Design Study: Phase 0
Preparation has started ahead of the kick-off meetingu With the proposal of a Work Breakdown Structure (WBS): to be
discussed togetherl i.e., a number of working groups in “Experiments” and in
“Phenomenology”u With the nomination of one high-profile convener for each working
groupl To plan and start the Exploration phase (Phase 1)
è … and possibly beyondl To propose names for working group co-conveners
è Targeting international collaboration and global effortl To propose names for sub-group conveners
è ibid. We do not start from scratch anyway
u Many synergies exist with linear collider studiesl And possibly with linear collider teams: contacts are more than
welcome !u Synergies with other circular e+e- colliders and with FCC-hh
whenever appropriateu A first look at the TLEP Physics case [JHEP01(2014)164] has
already been givenl Although many new aspects will come up during the design
studyè What can be done with, e.g., 1012 Z is beyond (current)
imagination
