Hard Exclusive Reactions at Jlab
- JLAB
Dedicated experiments to study Deeply Virtual Compton Scattering (DVCS) and Deeply Virtual Meson Production (DVMP) have been carried out at Jefferson Lab. DVCS helicity--dependent and helicity--independent cross sections and beam spin asymmetries have been measured, as well as cross sections and asymmetries for the $$\pi^0$$, $$\eta$$, $$\rho^0$$, $$\rho^+$$, $$\omega$$ and $$\phi$$ for exclusive electroproduction. The data were taken in a wide kinematic range in $Q^2$=1--4.5 GeV$^2$, $$x_B$$=0.1--0.5, and $|t|$ up to 2 GeV$^2$. The presented results offer a unique opportunity to study the structure of the nucleon at the parton level as one has access to Bjorken $$x_B$$ and momentum transfer to the nucleon $$t$$ at the same time.
