IRIS – Institutional Research Information System
IRIS è il sistema di gestione della ricerca dell’Università degli Studi di Milano-Bicocca.Il repository BOA è il modulo del sistema dedicato alla raccolta e alla disseminazione della produzione scientifica di Ateneo. Le pubblicazioni sono ricercabili per parola chiave attraverso il box nella barra orizzontale in alto oppure, mediante il pulsante Sfoglia, per "Afferenza", "Autore", "Titolo", "Tipologia" o "Settore scientifico-disciplinare".
IRIS contiene inoltre alcuni moduli dedicati alla registrazione dei progetti e dei contratti, e alla reportistica avanzata per le attività di valutazione della ricerca
EnglishThe product of the Λ0b(B0) differential production cross-section and the branching fraction of the decay Λ0bJ= pK.. (B0!J= K Λ (892)0) is measured as a function of the beauty hadron transverse momentum, pT, and rapidity, y. The kinematic region of the measurements is pT >20 GeV=c and 2:0>y>4:5. The measurements use a data sample corresponding to an integrated luminosity of 3fb..1 collected by the LHCb detector in pp collisions at centre-of-mass energies ps = 7 TeV in 2011 and ps = 8 TeV in 2012. Based on previous LHCb results of the fragmentation fraction ratio, fΛ0 b =fd, the branching fraction of the decay Λ0 b!J= pK.. is measured to be B(Λ0 bJ= pK..)=(3:17±0:04±0:07±0:34+0:45 ..0:28 )10..4 ; where the first uncertainty is statistical, the second is systematic, the third is due to the uncertainty on the branching fraction of the decay B0J= K Λ (892)0, and the fourth is due to the knowledge of fΛ0 b =fd. The sum of the asymmetries in the production and decay between Λ0 b and Λ 0 b is also measured as a function of pT and y. The previously published branching fraction of Λ0 b ! J= p.., relative to that of Λ0 b ! J= pK.., is updated. The branching fractions of Λ0 b!P+ c (!J= p)K.. are determined.
