Abstract

Forward single pi(0) production by coherent neutral-current interactions, vA -> vA pi(0), is investigated using a 2.8 x 10(20) protons-on-target exposure of the MINOS Near Detector. For single-shower topologies, the event distribution in production angle exhibits a clear excess above the estimated background at very forward angles for visible energy in the range 1-8 GeV. Cross sections are obtained for the detector medium comprised of 80% iron and 20% carbon nuclei with (A) = 48, the highest-< A > target used to date in the study of this coherent reaction. The total cross section for coherent neutral-current single pi(0) production initiated by the v(mu) flux of the NuMI low-energy beam with mean (mode) E-v of 4.9 GeV (3.0 GeV), is 77.6 +/- 5.0 (stat)(-) (+15.0)(16.8) (syst) x 10(-40) cm(2) pernucleus. The results are in good agreement with predictions of the Berger-Sehgal model.
