| Description: |
The STAR experiment reports new, high-precision measurements of the transverse single-spin asymmetries for 𝜋± within jets, namely the Collins asymmetries, from transversely polarized 𝑝↑𝑝 collisions at √𝑠=510 GeV. The energy-scaled distribution of jet transverse momentum, 𝑥T=2𝑝T,jet/√𝑠, shows a remarkable consistency for Collins asymmetries of 𝜋± in jets between √𝑠 =200 GeV and 510 GeV. This indicates that the Collins asymmetries are nearly energy independent, with, at most, a very weak scale dependence in 𝑝↑𝑝 collisions. These results extend to high-momentum scales (𝑄2≤3400 GeV2) and enable unique tests of evolution and universality in the transverse-momentum-dependent formalism, thus providing important constraints for the Collins fragmentation functions. |
