[Theory-seminars] Theory Seminar Monday - Shohini Bhattacharya

[Colin Egerer]

Hello All,

This coming Monday, April 10th, at 1:00 PM (EDT), Shohini Bhattacharya will give our next hybrid theory seminar. If you will be on-site and are comfortable doing so, please join us in room L102 of CEBAF Center. Otherwise, Shohini's seminar will also be provided virtually on our usual ZoomGov link: https://jlab-org.zoomgov.com/j/1611179843?pwd=M09CNTFpbFVZSW1IQlhIMGp3RUVHUT09

Please see below for the title and abstract.

Theory Seminar
Monday, April 10th at 1:00 PM

Shohini Bhattacharya (BNL)
will discuss "Manifestation of anomalies in Deep Virtual Compton Scattering"

Abstract:
We calculate the one-loop quark box diagrams relevant to polarized and unpolarized Deep Virtual Compton Scattering by introducing an off-forward momentum $l^\mu$ as an infrared regulator. Such a regularization enables us to unravel the poles $1/l^2$ related to the chiral anomaly in the polarized case and the trace anomaly in the unpolarized case. We interpret our results in terms of the relevant Generalized Parton Distributions, and discuss the implications of the poles on the QCD factorization for Compton amplitudes.


Have a pleasant weekend!
Caroline, Colin & Patrick
