[Theory-seminars] Reminder: Seminar TODAY

[schlegel at jlab.org]

Dear all,

Just a reminder that we have a seminar at 3pm in L102/4 this afternoon
(Monday):

**NOTE CHANGE OF TIME FOR SEMINAR ON MONDAY**

----------
Monday Nov 30th
*3pm*
L102/4

*Recent progress on two-boson exchange effects in electron scattering*

Peter Blunden (University of Manitoba, Canada)

This talk will be a review of recent work by our group and others on
the role of two-boson exchange in elastic electron-nucleon scattering,
focusing in particular on hadronic frameworks suitable for describing
data at low and moderate Q2. This will include the effects of
two-photon exchange (TPE) on elastic form factors, and the interference
of TPE and gamma-Z exchange on parity-violating form factors.

Also this week we have a cake seminar on Wednesday:

Wednesday Dec 2nd

*Estimate of Two-Photon Exchange in Elastic Electron-Proton Scattering:
QCD factorisation approach*

Nikolai Kivel (Bochum U. & Petersburg NPI)

Cake Sponsor: Christian

We estimate the TPE exchange contribution to elastic electron-proton
scattering at large momentum transfer Q2 using QCD factorisation approach.
Using several models for the nucleon distribution amplitudes,  we provide
estimates for existing data and ongoing experiments.
