Hi,
Our polarization experts such as Ralf Seidl and Sasha have had some email discussion about the polarization effect with crossing angles.
In the RHIC Retreat, basically, C-AD (Chuyu Liu and Wolfram Fischer) told us that what we saw ( a factor of 6-7) is “right” and real. Their previous calculation assuming Gaussian only profile is wrong. After the RHIC Retreat, I asked Chuyu and he sent us this file for his new calculation :

Hello Stefan,
This seems like a very important question that we should make sure to get right.
What is at stake here? Do we have guidance from CAD on crossing angle vs maximum luminosity?
Thanks Tony
