[Olympus] Report from the St. Petersburg workshop

[Michael Kohl]

Dear Colleagues,

the St. Petersburg workshop "Experimental and theoretical aspects of 
the proton form factors" was held this week July 9-11, 2012.
I would like to point you to the workshop website where the talks can be 
accessed, 
http://hepd.pnpi.spb.ru/hepd/olympus_2012/program.html

It was a very interesting meeting with many discussions.
Rebecca Russell gave a very nice presentation on OLYMPUS.

My take-home messages are that E. Tomasi-Gustafsson, Y. Bystritsky and 
E. Kuraev are able to describe all proton data with higher-order radiative 
corrections and claim that (hard) two-photon exchange is negligibly small. 
This is confronting the statements by other theory groups.

Interestingly, Novosibirsk has reported from run II from September 2011 - 
April 2012 at 1 GeV, and showed preliminary results. "Standard" radiative 
corrections were applied with the new MC method. They expect to publish 
the final results from both runs I and II within the next year.

The CLAS data analysis is in progress and preliminary results are expected 
for the DNP fall meeting (Oct 24-27 in Newport Beach, CA).

Best regards
    Michael
