Measurement of the charge asymmetry of electrons from the decays of W bosons produced in p p ¯ collisions at s =1.96 TeV MEASUREMENT of the CHARGE ASYMMETRY of ELECTRONS ... T. AALTONEN et al.

At the Fermilab Tevatron proton-antiproton (p (p) over bar) collider, high-mass electron-neutrino (e nu) pairs are produced predominantly in the process p (p) over bar -> W(-> e nu) + X. The asymmetry of the electron and positron yield as a function of th
