This summary provides an overview of the Higgs Factory Physics scenarios discussed in the meeting, including topics such as CP quantum numbers, CP violation, Higgs couplings, cross sections, and low-energy gamma-gamma options. It also explores potential physics programs and costs associated with the low-energy gamma-gamma option.

Summary of Collider Scenarios Bruce Schumm 6/19 Scenarios Meeting
Higgs Factory Physics • CP Quantum Numbers (longitudinal and transverse • photon pol) • CP Violation in the h,A,H loops • Higgs Couplings (widths) • • WW • Tot
4-5 1-2 `LHC WEDGE’ (meas)/ (SM) WW(meas)/ WW(SM)
Low-Energy Option Would be premier facility ~2010 • Physics…? • cross section • Charm, bottom spectroscopy • Polarized cross section • Quark/baryon hadronization • Heavy quark baryons • Photon structure • Bc ? SUSY Higgs?
Low-Energy Option Costs • Collisions not yet proven technology • Demonstrate all but • Short pulse train • High-power laser (100 J vs. 5 J) For ~ $10 M. To get to full physics program, more like (??) ¼ G$
