Abstract
We study power corrections in the Drell-Yan (DY) process using state-of-the-art predictions for both neutral and charged current production. For both types of DY processes, we account for power corrections arising from bottom and charm quark effects within a variable flavor number scheme. Our results show that these corrections become significant in the low- region. We also ensure proper treatment of overlapping contributions by carefully applying matching procedures to eliminate any double counting.
