Evidence for quark effects in high-energy d(j,p)n

Research output: Contribution to journalArticlepeer-review


Recoil proton polarization was measured in deuteron photodisintegration at dcm = 90° for photon energies up to 2.5 GeV. The induced polarization pv is consistent with vanishing above 1 GeV, consistent with expectations from perturbative quantum chromodynamics (pQCD) and in disagreement with meson-baryon calculations. However, polarization transfer observables are non-zero, indicating that hadron helicity is not conserved.
