Probing Vector Mesons in Deuteron Break-up Reactions

Understand

We study vector meson photoproduction from the deuteron at high momentum transfer, accompanied by break-up of the deuteron into a proton and neutron.

• The large $-t$ involved allows one of the nucleons to be identified as struck, and the other as a spectator to the $\gamma N\rightarrow VN$ subprocess.
• Corrections to the plane wave impulse approximation involve final state interactions (FSIs) between the struck nucleon or the vector meson, either of which is energetic, with the slow spectator nucleon.
• In this regime, the eikonal approximation is valid, so is employed to calculate the cross-section for the reaction.
