Hi Chip.
I am reluctantly okay with the new wording as a compromise, and also
support Chris' suggestion below of adding "(multi?)-TeV-scale lepton
colliders" to make sure accelerator R&D and physics studies continue for
these as well. That was a continuing problem with even the original
text that your other frontier convenors were struggling with.
Regards,
Rick
