Feedback from the  FCC physics workshop:

(1) Some people attending the workshop are not familiar with the ep colliders. Some of them even question the existence of the future ep colliders.  We add lots of introduction slides for our talks. I will suggest we should also add more introduction slides for our future talks.

(2) Kechen discussed a lot with Uta about how to measure the inclusive Higgs production in the neutral current (ZZ-fusion) process, which will be key to measure the total decay width of Higgs at ep. Our conclusion is we will start with the study of H->jj (bb/cc/gg, inclusively) process. Its precision at ep could be much better than pp. We also hope this study will give us some hints towards the final study of the Higgs inclusive decays. 

(3) About aTGC measurements, it is suggest that one can use the off-shell production of W or Z bosons to enhance the limits of these couplings. It might work. Please try if you are doing such studies.

(4) People asked some questions about effects on the new physics from the PDF measurements at ep colliders. There are some studies already, but not too many. More studies are needed and they are important to show the importance of ep colliders.

 

Please feel free to add more.

 

Best,

Kechen
