Jet physics plays an essential role in understanding the nuclear structure at short distance and properties of the hot and dense QCD matter in heavy-ion collisions. The forward rapidity in experiments such as LHCb provide a window for furthering these studies in a difference regime of energy and density. In this talk, I will discuss about jet and electroweak boson studies in p+A collisions which can help to provide constraints on parton distributions in large nuclei. I will also discuss jet quenching in the forward direction and their implication on jet tomography of hot QCD matter.
