Measurement of Deeply Virtual Compton Scattering Beam-Spin Asymmetries
Measurement of Deeply Virtual Compton Scattering Beam-Spin Asymmetries
The beam-spin asymmetries in the hard exclusive electroproduction of photons on the proton ($\stackrel{\ensuremath{\rightarrow}}{e}p\ensuremath{\rightarrow}ep\ensuremath{\gamma}$) were measured over a wide kinematic range and with high statistical accuracy. These asymmetries result from the interference of the Bethe-Heitler process and of deeply virtual Compton scattering. Over the whole kinematic range (${x}_{B}$ from 0.11 …
