Hi everyone,

This week's nuclear/hadronic physics seminar will take place on Thursday 
at 3:30pm in Small Hall 122. Buddhini Waidyawansa, postdoctoral fellow 
at Jefferson Lab, will be presenting her research on transverse 
asymmetries in polarized electron scattering. An abstract is appended.

Cheers,

Wouter

Schedule of future fall nuclear physics seminars:

Nov 12: Simona Malace (JLab), structure of the nucleon

Nov 19: Kalyan Allada (MIT), transversity in nucleons

Dec 3: Ciprian Gal (UVA), parity violation results with the Qweak experiment

Beam normal single spin asymmetries in electron scattering

Abstract:  A beam normal single spin asymmetry, is generated by the 
scattering of transversely polarized electrons from unpolarized targets. 
This parity conserving observable provides direct access to the 
imaginary part of the two photon exchange amplitude. Because it can be 
calculated from the sum of the amplitudes for all on-shell intermediate 
states, a measurement provides an integral test of our understanding 
of the fundamental gamma + nucleon --> X  processes. In addition this 
observable is also of special interest to experiments making precision 
parity-violating asymmetry measurements because small amounts of 
residual transverse polarization in the beam can lead to percent-level 
corrections. However, this asymmetry is highly suppressed hence is 
only accessible with apparatus designed to measure asymmetries at the 
few percent level. I will discuss the theoretical and experimental 
status of beam normal single spin asymmetry and their implications on 
the two-photon exchange theories.
