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

= 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)

Lepton Collider: Physics, Experiments, Detectors 12

Page 13: Introduction

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
