Measurement of CNGS muon neutrino speed with Borexino
We have measured the speed of muon neutrinos with the Borexino detector using
short-bunch CNGS beams. The final result for the difference in time-of-flight
between a =17 GeV muon neutrino and a particle moving at the speed of light
in vacuum is {\delta}t = 0.8 \pm 0.7stat \pm 2.9sys ns, well consistent with
zero.Comment: 6 pages, 5 figure

Rotational Surfaces in and Solutions in the Nonlinear Sigma Model
The Gauss map of non-degenerate surfaces in the three-dimensional Minkowski
space are viewed as dynamical fields of the two-dimensional O(2,1) Nonlinear
Sigma Model. In this setting, the moduli space of solutions with rotational
symmetry is completely determined. Essentially, the solutions are warped
products of orbits of the 1-dimensional groups of isometries and elastic curves
in either a de Sitter plane, a hyperbolic plane or an anti de Sitter plane. The
main tools are the equivalence of the two-dimensional O(2,1) Nonlinear Sigma
Model and the Willmore problem, and the description of the surfaces with
rotational symmetry. A complete classification of such surfaces is obtained in
this paper. Indeed, a huge new family of Lorentzian rotational surfaces with a
space-like axis is presented. The description of this new class of surfaces is
based on a technique of surgery and a gluing process, which is illustrated by
an algorithm.Comment: PACS: 11.10.Lm; 11.10.Ef; 11.15.-q; 11.30.-j; 02.30.-f; 02.40.-k. 45

Absence of day-night asymmetry of 862 keV Be-7 solar neutrino rate in Borexino and MSW oscillation parameters
We report on a search for the day-night asymmetry of the Be-7 solar neutrino
rate measured by Borexino at the Laboratori Nazionali del Gran Sasso (LNGS),
Italy. The measured value, Adn=0.001 +- 0.012 (stat) +- 0.007 (syst), shows the
absence of a significant asymmetry. This result alone rejects the so-called LOW
solution at more than 8.5 sigma. Combined with the other solar neutrino data,
it isolates the Large Mixing Angle (LMA) -- MSW solution at DeltaChi2 > 190
without relying on the assumption of CPT symmetry in the neutrino sector. We
also show that including the day-night asymmetry, data from Borexino alone
restricts the MSW neutrino oscillations to the LMA solution at 90% confidence
level.Comment: 5 figures, published on Phys. Lett
