Matthias Burkardt (NMSU/Jefferson Lab)

TL;DR
This paper discusses how beam charge asymmetry in DVCS with positrons can reveal information about the real and imaginary parts of the scattering amplitude, enhancing understanding of proton structure.
Contribution
It introduces analysis of beam charge asymmetry with positrons to extract detailed information about DVCS amplitudes, focusing on the real part.
Findings
Beam charge asymmetry isolates the real part of DVCS amplitude.
Analysis provides insights into the proton's internal structure.
Potential to improve GPD modeling.
Abstract
The beam charge asymmetry helps to isolate the real part of the deeply virtual Compton scattering (DVCS) amplitude. It is discussed what information can be gained both from the real and imaginary part of the DVCS amplitude.
