In the present work, k T -factorization formalism is applied to compute the exclusive dilepton production by timelike Compton scattering (TCS) in eA, pA, and AA collisions. The nuclear effects are investigated considering heavy and light ions. The production cross section in terms of the invariant mass and rapidity distribution of the lepton pair is shown. The analysis is done for electron-ion collisions at the Large Hadron-Electron Collider (LHeC), its high-energy upgrade (HE-LHeC), and at the
