The neutrino–nucleon and anti-neutrino–nucleon differential cross-sections are measured in the range 0.01 < x < 0.7, 0.05 < y < 0.95, 10 < Eν < 200 GeV. We extract the neutrino–nucleon structure functions F2(x,Q^2), xF3(x,Q^2), and R(x,Q^2) and compare these with results from other experiments.

Abstract
After completion of the data taking for the νµ → ντ oscillation search, the CHORUS lead–scintillator calorimeter was used in the 1998 run as an active target. High-statistics samples of charged-current interactions were collected in the CERN SPS west area neutrino beam. This beam contained predominantly muon (anti-)neutrinos from sign-selected pions and kaons. We measure the flux and energy spectrum of the incident neutrinos and compare them with beam simulations. The neutrino–nucleon and anti-neutrino–nucleon differential cross-sections are measured in the range 0.01 < x < 0.7, 0.05 < y < 0.95, 10 < Eν < 200 GeV. We extract the neutrino–nucleon structure functions F2(x,Q^2), xF3(x,Q^2), and R(x,Q^2) and compare these with results from other experiments.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
