This page presents the preliminary results on the transverse spin transfer D_TT vs z of Lambda hyperon for 200 GeV p+p collisions of run 15 with the same run list used in the D_TT vs pt preliminary result(DTT vs pt preliminary result).

2015 D_TT vs z Preliminary Results, request in September 30th 2021, after the STAR Collaboration Meeting.

The preliminary plots and the relevant slides are list here:

Figure 1: D_TT results of Lambda and Anti-Lambda hyperon as the function of  z  at 0 < eta 1.2 and -1.2 < eta < 0.
z is the longitudinal momentum fraction of \Lambda hyperon to the jet.
