Abstract We study a few basic photon- and lepton-initiated processes at the LHC which can be computed using the recently developed photon and lepton parton densities. First. we consider the production of a massive scalar particle initiated by lepton-antilepton annihilation and photon-photon fusion as representative examples of searches of exotic particles. Then we study lepton-lepton ... https://www.diegojavierfares.com/mega-pick-LSU-Tigers-NCAA-Bold-Color-Tote-Bag-p23366-amazing-save/
