Neutrino results from the Fermilab 15-foot bubble chamber using neon-hydrogen mixtures
Description
Neutrino results from the FNAL 15-foot bubble chamber, using two different neon-hydrogen mixtures are reviewed. Included are the measurements from four different experiments of the dilepton, or μe rate, which appear to be consistent with the charm production interpretation for this process. Also mentioned is a study of the scaling variable distributions for antineutrinos, which shows no anomalous threshold, consistent with the usual four-quark model, but indicates a slight scale breaking. The ratio of anti νn to anti νp cross sections has been extracted from the same data and is also consistent with the quark model. A study of the hadronic state produced by electron (anti)neutrinos in neon is summarized, with the conclusion that nuclear rescattering effects are the same as for hadron interactions. (orig.)
Abstract (German)
Es werden Neutrinoexperimente beschrieben, die mit Hilfe der 15-Fuss Blasenkammer am FNAL und zwei verschiedenen Neon-Helium-Mischungen durchgefuehrt wurden. Darunter sind Messungen aus 4 verschiedenen Experimenten zur Untersuchung des Dileptons oder der μe-Rate, die anscheinend mit der Interpretation der Charmproduktion in diesem Prozess konsistent ist. Ausserdem wird eine Untersuchung der Verteilung der Skalenvariablen fuer Antineutrinos erwaehnt, die in Uebereinstimmung mit dem herkoemmlichen vier-Quarkmodell keine anomale Schwelle besitzt, jedoch eine geringe Skalenbrechung zeigt. Das Verhaeltnis der anti νn- und anti νp-Wirkungsquerschnitte wurde aus denselben Daten gewonnen und stimmt ebenfalls mit dem Quarkmodell ueberein. Eine Untersuchung des hadronischen Zustands, erzeugt durch Elektron (anti)neutrinos in Neon, wird zusammengefasst mit der Schlussfolgerung, dass die nuklearen Rueckstreueffekte fuer die hadronischen Wechselwirkungen dieselben sind.
