Status of the CHORUS structure function measurement

Abstract The CHORUS detector, designed to search for neutrino oscillations, was used to record a high-statistics sample of neutrino and anti-neutrino interactions during the extension of the experiment in 1998, using the lead calorimeter as a target. The measurement of the structure functions F 2 ( χ , Q 2 ) and χF 3 ( χ , Q 2 ) is underway.
