Understand

The SIDIS transverse spin asymmetries weighted with powers of $P_T$, the hadron transverse momentum in the $\gamma N$ reference system,have been introduced already twenty years ago and are considered quite interesting.

While the amplitudes of the modulations in the azimuthal distribution of the hadrons are the ratios of convolutions over transverse momenta of the transverse--momentum dependent parton distributions and of the corresponding fragmentation functions, and can be evaluated analytically only making assumptions on the transverse--momentum dependence of these functions, the weighted asymmetries allow to solve the convolution integrals over transverse--momenta without those assumptions.
Using the high statistics data collected in 2010 on transversely polarized proton target COMPASS has evaluated in x-bins the $P_T$ weighted Sivers asymmetry which is proportional to the product of the first transverse moment of the Sivers function and of the fragmentation function.
The results are compared to the standard unweighted Sivers asymmetry.
