Highlights from Muon Scattering at CERN
A review is given of recent results from the deep inelastic muon scattering program at CERN, focusing on high statistics measurements of scaling violations and tests of QCD, and on past and future experiments to measure the spin structure functions of the nucleon.
متن کاملInequality for Electron and Muon Scattering from Nucleons
Equation (1) has the classic structure of a sum rule except for the factor of 2 mismatch. It occurs because half of the point cross section comes from the isoscalar current, about (3) E and E' are incident and final laboratory energies of the electron, 8 the scattering angle, and q'=4EE'sin'(8/2). o is the total (elastic + inelastic) electron-proton cross section and cr &S the cross-section fro...
متن کاملWeak Neutral Currents in Electron and Muon Scattering*
Contributions to inelastic scattering arising from the interference of a weak neutral current with the electromagnetic current are calculated using the Weinberg model and the quark parton model. These interferences produce nonvanishing (dd daf) , -(L) (do d$(R)), (dostL) do-(R)) which give rise to sizeable affects when compared to the purely electromagnetic scattering. (Submitted to Phys. Rev. ...
متن کاملInequality for Backward Electron - and Muon - Nucleon Scattering at High Momentum Transfer
From a sum rule for backward up scattering, valid only in the limit of large four-momentum transfer q2, we obtain an inequality for backward e-p inelastic scattering which depends ,upon the commutator of space components of isospin currents. Given chiral U(6) X U(6) current algebra, the total backward scattering at fixed large q2. is predicted to be at least as great as that from a point Dirac ...
