A new approach to determine the LHC luminosity is investigated. Instead of employing the proton-proton luminosity measurement, we suggest to measure directly the parton-parton luminosity. It is shown that the electron and muon…
We explore the ability of the Large Hadron Collider to measure the mass of the W boson. We believe that a precision better than 15 MeV could be attained, based on a year of operation at low luminosity (10^{33} cm^-2 s^-1). If this is true,…
