KaonLT BSA Analysis of p(e,e'pi+)n

These data present the Beam-Spin Asymmetry (A_LU) in exclusive pion electroproduction, p(e,e'pi+)n as measured in the KaonLT experiment. Files titled with the central kinematics of the setting, e.g. "Q2p1x0p21.csv," contain A_LU as a function of phi for each bin in Mandelstam t for the given setting. The file "ALUsinphi.csv" contains experimental kinematics and a summary of the sin(phi) moment of the asymmetry, and its errors, in each t-bin, across all settings.

These data were collected at Jefferson Laboratory Hall C as a part of the KaonLT experiment. They were analyzed using a combination of the standard Hall C analysis software and standalone analysis scripts in CERN ROOT.

These data are intended to accompany the paper, "Probing hard/soft factorization via beam-spin asymmetry in exclusive pion electroproduction from the proton," by A.C. Postuma et al (KaonLT Collaboration), which will be submitted to Physics Letters B.
