- From Huey-Wen Lin to Everyone: (11:55 AM) ?Hi Fred, can you comment on what the opportunities will be for studying spin physics and generalized parton distributions (GPDs) at LHeC and FCC? Fred: Yes, can run with polarized beams and do these studies. - Complementarity with FCC-hh - yes, the phase space explored here is exactly whatÕs relevant for FCC-hh.Ê - Also for HL-LHC, improved PDFs will allow experiments to go back and reduce uncertainties of HL-LHC measurements. From Fred Olness to Everyone: (12:13 PM) ?FYI: LHeC 2020 White paper?https://cds.cern.ch/record/2706220?ln=en
