This page presents the preliminary results on the longitudinal spin transfer of \Lambda hyperon for 200 GeV p-p collisions of run 15.
The preliminary plots and the relevant slides are list here:

Preliminary Plots:

description: the data points have been shifted slightly for clarity.

Plot 1
DLL results of Lambda and Anti-Lambda hyperon as the function of transverse momentum pT at 0 < eta 1.2 and -1.2 < eta < 0.
The Anti-Lambda results are offset to slightly larger pT values for clarity.

Plot 2
Comparison between the run 15 DLL results with the published results using run 09 data set at 0 < eta < 1.2.
The run 15 results are offset to slightly smaller pT values and run 09 results to larger pT values for clarity.
