We report some preliminary differential cross section results for the γ d → KSΛ(p) reaction using a circularly-polarized photon beam and an unpolarized LD2 target. The data was collected at the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab. For this study the photon energy ranged from 1.3 to 2.53 GeV, which covers from the reaction threshold through the nucleon resonance regimes. The acceptance- and flux-corrected yields show peaks at the center-of mass energies W = 1.7 and W = 1.9 GeV. These first-time results will aid in unraveling the spectrum of non-strange excited baryons.

The 90° differential cross section of the 11B(α,γ0)15N reaction has been measured at α-particle energies from 5.74 to 17.80 MeV. The γ rays have been detected by a 23 cm long × 23 cm diameter NaI(Tl) crystal spectrometer enclosed in a plastic scintillator anticoincidence shield. The yield curve shows three well separated resonances at Eexc = 16.29 ± 0.15, 18.88 ± 0.20, and 21.26 ± 0.20 MeV.

Vector Meson Production

The total and differential cross section for exclusive vector meson electro- and photoproduction above the resonance region (2<W<3 GeV ) were measured at Jefferson Laboratory covering a wide kinematic range (0<Q2<5 GeV 2/c2 and 0<-t<5 GeV 2). These measurements provide a unique tool to investigate the transition between soft and hard physics. Our data indicates that this regime can be successfully and consistently described by using the so called effective partonic degrees of freedom.
