IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishDifferential cross sections dσ/dy have been measured in semileptonic neutral- and charged-current reactions induced by neutrinos and antineutrinos. The comparison of the neutral- and the charged-current differential cross sections allows the direct determination of the chiral coupling of the neutral neutrino-antineutrino current to left- and right-handed quarks. The result, with a value of g_R^2 = 0.042±0.010, is the first direct determination, with a significance of more than four standard deviations, of a non-zero value of g_R.

| Abstract: | Differential cross sections dσ/dy have been measured in semileptonic neutral- and charged-current reactions induced by neutrinos and antineutrinos. The comparison of the neutral- and the charged-current differential cross sections allows the direct determination of the chiral coupling of the neutral neutrino-antineutrino current to left- and right-handed quarks. The result, with a value of g_R^2 = 0.042±0.010, is the first direct determination, with a significance of more than four standard deviations, of a non-zero value of g_R. | |
