Search for a Dark Photon in Electro-Produced $e^{+}e^{-}$ Pairs with the Heavy Photon Search Experiment at JLab

P. H. Adrian, N. A. Baltzell, M. Battaglieri, M. Bondí et autres

The Heavy Photon Search experiment took its first data in a 2015 engineering run using a 1.056 GeV, 50 nA electron beam provided by CEBAF at the Thomas Jefferson National Accelerator Facility, searching for an electro-produced dark photon. Using 1.7 days (1170 …

Differential cross sections and recoil polarizations for the reaction γp→K+Σ0

B. Dey, C. A. Meyer, M. Bellis, M. McCracken et autres

High-statistics measurements of differential cross sections and recoil polarizations for the reaction $\ensuremath{\gamma}p\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\Sigma}}^{0}$ have been obtained using the CLAS detector at Jefferson Lab. We cover center-of-mass energies ($\sqrt{s}$) from 1.69 to 2.84 GeV, with an extensive coverage in the ${K}^{+}$ production angle. …
