  We present the first determination of transverse momentum dependent (TMD)
photon densities with the Parton Branching method. The photon distribution is
generated perturbatively without intrinsic photon component. The input
parameters for quarks and gluons are determined from fits to precision
measurements of deep inelastic scattering cross sections at HERA. The TMD
densities are used to predict the mass and transverse momentum spectra of very
high mass lepton pairs from both Drell-Yan production and Photon-Initiated
lepton processes at the LHC.
