This study overcomes intrinsic limitations of previous research by using a recoil-free axis, achieving unprecedented next-to-next-to-leading logarithmic accuracy with small non-perturbative corrections. The research found that the choice of axis makes the observable robust in the presence of a large background, and the azimuthal angle distribution remains minimally changed when determined using only charged particle tracks.
The azimuthal decorrelation between a vector boson and a jet is an essential hard probe in high energy proton-proton and heavy-ion collisions. We overcome intrinsic limitations of previous studies by using a recoil-free axis, achieving unprecedented next-to-next-to-leading logarithmic accuracy with small non-perturbative corrections. This choice of axis also makes the observable robust in the presence of a large background. Furthermore, the azimuthal angle distribution is minimally changed when determined using only charged particle tracks, which offer superior angular resolution for precise measurements. Our effective field theory includes full jet dynamics, and we find contributions from linearly-polarized gluon transverse momentum distributions in the initial and final state.
