Acesso em: 16 maio 2023.e- 2470-00292470-0010http://repositorio.bc.ufg.br/handle/ri/22588Forward single π0 production by coherent neutral-current interactions, νA → νAπ0, is investigated using a 2.8 × 1020 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 hAi ¼ 48, the highest-hAi target used to date in the study of this coherent reaction. The total cross section for coherent neutral-current single π0 production initiated by the νμ flux of the NuMI low-energy beam with mean (mode) Eν of 4.9 GeV (3.0 GeV), is 77.6 5.0ðstatÞþ15.0 −16.8 ðsystÞ × 10−40 cm2 pernucleus. The results are in good agreement with predictions of the Berger-Sehgal model.engAcesso AbertoArtigo10.1103/PhysRevD.94.072006
