Preliminary results of run15 double spin asymmetry of the in-jet Lambda hyperon and Kshort meson. This results are going to shown at SPIN2023.

V0Jet Reconstruction
The V0Jet Tree used in this analysis has already been used in the run15 Lambda spin transfer (DLL) analysis. Details about the V0Jet reconstruction can be found the following:

Preliminary Plots

Figure 1.
Lambda and Kshort ALL vs their transverse momentum.
The horizontal values of Lambdabar and KS0 have been shifted to larger values for clarity.
