[Theory-seminars] Theory Seminar Monday - Yuxun Guo

[Colin Egerer]

Hello All,

This coming Monday, April 25th at 1PM (EDT), Yuxun Guo will give a (virtual) theory seminar on https://jlab-org.zoomgov.com/j/1611179843?pwd=M09CNTFpbFVZSW1IQlhIMGp3RUVHUT09

Please see below for the title and abstract of Yuxun's talk.

Theory Seminar
Monday, April 25th at 1:00PM

Yuxun Guo (University of Maryland)
will discuss "GPDs and high order effect in DVCS"

Abstract:
I will talk about various aspects of generalized parton distributions (GPDs) including their physical intuitions and measurements from deeply exclusive process. I will talk about the deeply virtual Compton scattering (DVCS) process as an example and show how the DVCS cross-sections can be used to probe the twist-two and twist-three GPDs through the so-called Compton form factors (CFFs). I will discuss various higher order effects that are relevant to the precise determination of leading order CFFs and potentially twist-three CFFs as well. In addition, I will present some numeric studies of the kinematical dependence of the twist-two and twist-three cross-sections at typical JLab 6 GeV and 12 GeV kinematics and discuss the optimal regions for separating the leading-twist effects from the higher-twist ones.

Have a pleasant weekend!
Caroline, Colin & Patrick
