Description
In this work, we investigate the nuclear modification effects in transverse momentum dependent
(TMD) observables by implementing a nuclear covariance matrix in the treatment of theoretical uncertainties. Global QCD analysis is performed with the aforementioned nuclear covariance matrix to verify its equivalence with the traditional approach of including a nuclear correction parameter. The data analyzed are the Drell-Yan $q_T$-differential data in $pA$ and $\pi A$ collisions. In addition, we also perform global QCD analysis with no treatment for the nuclear effects, verifying the necessity of implementing the nuclear corrections.
