Description
The transverse spin transfer of $\Lambda$ hyperons in proton+proton collisions can provide insights into the polarized fragmentation function and the transversity distribution of the nucleon.
In this contribution, we report the first measurement of the transverse spin transfer of $\Lambda$ and $\bar{\Lambda}$ hyperons along the polarization direction of the outgoing quark in transversely polarized proton+proton collisions at RHIC.
The data were taken in 2012 with the STAR detector at $\sqrt{s}=200\,\mathrm{GeV}$ with an integrated luminosity of $18.4\, \mathrm{pb}^{-1}$ and covered hyperon transverse momenta up to $8\,\mathrm{GeV/c}$.
The beam polarization was about 63% during our data taking period.
