Tracking for CLAS12

We present a conceptual design for a tracking system for CLAS12, an upgraded version of the CLAS detector planned for the Jlab upgrade. In addition to a description of the proposed detectors, we also show a simulation of their expected performance. 1 Constraints and Requirements Jlab is planning to upgrade its present 6 GeV accelerator to 12 GeV. To take advantage of the new physics opportuniti...

Threshold pion electroproduction at large momentum transfers

Exclusive vector meson electroproduction at HERA

Exclusive electroproduction of light vector mesons is a particularly good process for studying the transition from the soft to the hard regime of strong interactions, the former being well described within the Regge phenomenology while the latter by perturbative QCD (pQCD). Among the most striking expectations [1] in this transition is the change of the logarithmic derivative δ of the cross sec...

1 Hyperon photo - and electroproduction at CLAS

(Received: February 7, 2008) The large acceptance and high multiplicity capabilities of the CLAS detector make it possible to study a wide range of previously unmeasured strange baryon production processes. Studies of the decay angular distributions of electroproduced strange baryons have yielded several interesting new results. The Λ(1520) electroproduction decay angular distributions shed lig...
