Upper limits for the photoproduction cross section for the Phi--(1860) pentaquark state off the deuteron

H. Egiyan, J. Langheinrich, R. W. Gothe +10

We searched for the Phi--(1860) pentaquark in the photoproduction process off the deuteron in the Xi- pi- decay channel using CLAS. The invariant mass spectrum of the Xi- pi- syste…

Search for a new gauge boson in the Experiment (APEX)

S. Abrahamyan, Z. Ahmed, K. Allada +63

We present a search at Jefferson Laboratory for new forces mediated by sub-GeV vector bosons with weak coupling to electrons. Such a particle can be produced in electron-…

Precise Measurements of Beam Spin Asymmetries in Semi-Inclusive production

M. Aghasyan, H. Avakian, P. Rossi +151

We present studies of single-spin asymmetries for neutral pion electroproduction in semi-inclusive deep-inelastic scattering of 5.776 GeV polarized electrons from an unpolarized hy…

Low Q^2 measurements of the proton form factor ratio

G. Ron, X. Zhan, J. Glister +84

We present an updated extraction of the proton electromagnetic form factor ratio, mu_p G_E/G_M, at low Q^2. The form factors are sensitive to the spatial distribution of the proton…
