Description
We present the results of the recent study published in Phys.Rev.Lett. 126 (2021) 4, 041801, where the PDF uncertainty affecting the MW determination at the LHC is estimated keeping into account the full correlations information from the PDF at the level of the differential distribution used to extract $M_W$, namely $p_T^l$.
We find that keeping these correlations into account can reduce significantly the PDF uncertainty (once other sources of uncertainties are under control) so that it should not represent a bottleneck in reaching the ultimate precision in the MW determination at hadron colliders.
