Abstract:

This Letter reports new results from the MINOS experiment based on a two-year exposure to muon neutrinos from the Fermilab NuMI beam. Our data are consistent with quantum-mechanical oscillations of neutrino flavor with mass splitting |Deltam2| = (2.43+/-0.13) x 10(-3) eV2 (68% C.L.) and mixing angle sin2(2theta) > 0.90 (90% C.L.). Our data disfavor two alternative explanations for the disappearance of neutrinos in flight: namely, neutrino decays into lighter particles and quantum decoherence of neutrinos, at the 3.7 and 5.7 standard-deviation levels, respectively.

Abstract:

A first measurement is reported of the longitudinal proton structure function F L (x, Q 2) at the ep collider HERA. It is based on inclusive deep inelastic e + p scattering cross section measurements with a positron beam energy of 27.5 GeV and proton beam energies of 920, 575 and 460 GeV. Employing the energy dependence of the cross section, F L is measured in a range of squared four-momentum transfers 12 ≤ Q 2 ≤ 90 GeV 2 and low Bjorken x 0.00024 ≤ x ≤ 0.0036. The F L values agree with higher order QCD calculations based on parton densities obtained using cross section data previously measured at HERA. © 2008 Elsevier B.V. All rights reserved.
