Summary
Quarks and leptons are the only pointlike particles known so far. However, a search for a proton-breaking mechanism in high-energy neutrino-nucleon interactions had never been performed. We present here the results of the first experiment in this field.
Riassunto
Le uniche particelle puntiformi finora conosciute sono i quark ed i leptoni. Tuttavia non è mai stata effettuata una ricerca intesa a mettere in evidenza un meccanismo di rottura del protone nelle interazioni di neutrini ad alta energia su nucleoni. In questo lavoro sono presentati i risultati del primo esperimento realizzato in questo campo.
Реэюме
Кварки и лептоны являются единственными точечно-подобными частицами, иэвестными до сих пор. Однако поиск механиэма, приводяшего к раэвалу протона, при высоких знергиях в нейтрино-нуклонных вэаимодействиях никогда не был проведен. В зтой работе мы приводим реэультаты первого зксперимента в зтой области.
