Abstract We present an analysis of the nucleon strange sea extracted from a global Parton Distribution Function fit including the neutrino and anti- neutrino dimuon data by the CCFR and NuTeV collaborations, the inclusive charged lepton-nucleon Deep Inelastic Scattering and Drell-Yan data. The (anti-)neutrino induced dimuon analysis is constrained by the semi- leptonic charmed-hadron branching ratio $B_\mu=(8.8\pm0.5)\%$, determined from the inclusive charmed hadron measurements performed by the FNAL-E531 and CHORUS neutrino emulsion experiments. Our analysis yields a strange sea suppression factor $\kappa(Q^2=20~{\rm GeV}^2)=0.62 \pm 0.04$, the most precise value available, an $x$-distribution of total strange sea that is slightly softer than the non-strange sea, and an asymmetry between strange and anti-strange quark distributions consistent with zero (integrated over $x$ it is equal to $0.0013 \pm 0.0009$ at $Q^2=20~{\rm GeV}^2$). A predictions for the differential cross sections of the dimuon production in the $\nu Fe$ collisions are calculated for the NOMAD energy spectra. | |||

Session 8 Non-accelerator experiments | |||
00:40 / 00:05 | Oleg Smirnov (JINR) Real time detection of Be-7 solar neutrinos by Borexino |
||
Abstract Borexino is a first real-time detector sensitive to low-energy solar neutrinos. The main goal of the experiment is the measurement of the flux of monoenergetic neutrinos originating from the capture of electrons on Be-7 in the sun's core with a precision of at least 5%. Due to the very low level of natural radioactivity achieved in Borexino, collaboration succeded to detect for the first time the solar neutrinos in sub-MeV region. Unique properties of the detector make it an appropriate tool to address other topics in neutrino physics and astrophysics. The status of the Borexino experiment after one year of the data taking and perspectives for the near future are presented. | |||
