Boer-Mulders effect in the unpolarized pion induced Drell–Yan process at COMPASS within TMD factorization

Abstract We investigate the theoretical framework of the $$\cos 2\phi $$ cos2ϕ azimuthal asymmetry contributed by the coupling of two Boer-Mulders functions in the dilepton production unpolarized $$\pi p$$ πp Drell–Yan process by applying the transverse momentum dependent factorization at leading or...
