<div style="margin:0px;font-size:12pt;background-color:rgb(255, 255, 255)"><span style="margin:0px">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.</span><u><b><br>
