1 Cool Copper Collider - Beam Background Studies

Speakers: Elias Mettner (UW-Madison), Abdollah Mohammadi (UW-Madison)

The error in this plot: we have been calculating the COM energy from the laboratory frame. A plot from the correct frame (from Thorsten):

With bump representing the Z Mass. So the bump in this plot:

Is the radiative return of the Z in the laboratory frame.
I am going to plot this myself to make sure we see similar results. I have also simulated some e+e- -> ZH events where we should hopefully see no bump whatsoever, as confirmed by another plot from Thorsten:

This confirms that this was the issue, and now we are ready to begin modifying WHIZARD with Tim Barklow's instructions.

2 CCC Background studies + H > aa > b,b tau,tau
