The double spin asymmetry in exclusive TT+ electro-production with CLAS

Research output: Contribution to conference › Paper › peer-review

Abstract

The eg1b run was conducted using CLAS at Jefferson Lab in 2000 by the CLAS collaboration. A 1.6 GeV - 5.6 GeV polarized electron beam and polarized nuclear targets (composed of NH₃ and ND₃) were used, allowing single and double spin asymmetries to be measured. This analysis deals with the double spin asymmetry A^|| in the exclusive production of positive pions from a polarized proton (ep → eπ+n). The double spin asymmetry was measured as a function of the four kinematic variables W, Q², cos θ^*, and φ^*. The value of this asymmetry can be used to help determine the spin structure of the resonances, due to its sensitivity to the spin dependent parts of the cross section. A brief description of the experimental setup will be given, and preliminary results for the asymmetry will be shown.
