I think Jim Boyce and I were at that workshop, but am glad

Future Colliders for Particle Physics - "Big and Small"
<br>
Frank Zimmermann
<br>
(Submitted on 9 Jan 2018)
<br>

Discoveries at high-energy particle colliders have
established the standard model of particle physics.
Technological innovation has helped to increase the collider
energy at a much faster pace than the corresponding costs. New
concepts will allow reaching ever higher luminosities and
energies throughout the coming century. Cost-effective
strategies for the collider implementation include staging. For
example, a future circular collider could first provide
electron-positron collisions, then hadron collisions
(proton-proton and heavy-ion), and finally the collision of
muons. Cooling-free muon colliders, realizable in a number of
ways, promise an attractive and energy-efficient path towards
lepton collisions at tens of TeV. While plasma accelerators and
dielectric accelerators offer unprecedented gradients, the
construction of a high-energy collider based on these new
technologies still calls for significant improvements in cost
and performance. Pushing the accelerating gradients or bending
fields ever further, the breakdown of the QED vacuum may set an
ultimate limit to electromagnetic acceleration. Finally, some
ideas are sketched for reaching, or exceeding, the Planck
energy.
