Hi Michael, I understand the point about the timelines, but I think if we are talking about "consensus" points, I think it became fairly clear at Snowmass that it's almost inconceivable that we can get complete understanding of the higgs / DM / EWSB without building something like VLHC, and we should state that we recognize that such machine is necessary in the future. -y On Aug 20, 2013, at 2:26 PM, "Peskin, Michael E." <[log in to unmask]> wrote: > > > Folks, > > I do agree that VLHC received wide interest at Snowmass. > > However, it is also important to recognize that the time scales for ILC and VLHC are > very different.
