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. On the practical side, no one today is entertaining a proposal for a 100 TeV pp collider. On the physics side, we are just beginning the serious studies of the capabilities of a 100 TeV collider. Only a few results were shown at Snowmass for the 33 TeV machine, and only one, I think, for the 100 TeV machine. (There will be more 100 TeV results in the final writeups.) In the summaries, Chip and I put a statement about ILC into the highest level executive summary. P5 will need to make a statement about ILC, so this input, which is strictly limited to the physics case and does reflect a consensus at Snowmass, is needed. There is a brief statement about the 100 TeV machine in the latest version of the Executive Summary, and a longer statement in the 5-page Energy Frontier summary. These reflect our attitude that the 100 TeV is important, but the issue is getting ready for a proposal in 2020, not making a decision today. If you would like it another way, please send some explicit language to this group. And, please take into account that space in the highest level executive summary is extremely limited. We can make two points strongly -- which is what we tried to do -- or make many points of which none registers above background.

I think the support for an eventual 100 TeV pp collider is very strong, certainly not less strong than a Higgs factory.

I strongly agree. Even given different timescales for VLHC and ILC, the way Markus phrased it is right on. -y ________________________________ Use REPLY-ALL to reply to list To unsubscribe from the SNOWMASS-EF list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=SNOWMASS-EF&A=1 ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the SNOWMASS-EF list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=SNOWMASS-EF&A=1
