Neutrino Physics
The fundamental properties of neutrinos are reviewed in these lectures. The
first part is focused on the basic characteristics of neutrinos in the Standard
Model and how neutrinos are detected. Neutrino masses and oscillations are
introduced and a summary of the most important experimental results on neutrino
oscillations to date is provided. Then, present and future experimental
proposals are discussed, including new precision reactor and accelerator
experiments. Finally, different approaches for measuring the neutrino mass and
the nature (Majorana or Dirac) of neutrinos are reviewed. The detection of
neutrinos from supernovae explosions and the information that this measurement
can provide are also summarized at the end.Comment: 50 pages, contribution to the 2011 CERN-Latin-American School of

Oscillation parameters present: Session summary
© Copyright owned by the author(s) under the terms of the Creative Commons. Session I of the Neutrino Oscillation Workshop 2018 Conference, “Neutrino Oscillations: Present”, is summarised. Results were presented by the currently-running long-baseline oscillation experiments T2K and NOvA, as well as from the accelerator experiments OPERA and MiniBooNE. Status reports and results from experiments using short-baseline accelerator neutrinos (ICARUS and MicroBooNE), atmospheric neutrinos (Super-K, IceCube and ANTARES), and those from reactors (Daya Bay and Double Chooz), and from the Sun and the Earth (Borexino) were also presented. Our current knowledge of neutrino oscillation parameters depends significantly on the experimental inputs that inform us of details of the production and interactions of neutrinos, which were presented by the NA61/SHINE hadron production experiment and cross section measurements from T2K and MINERvA, as well as a review of the status of our understanding of neutrino production at nuclear reactors. The session also included theoretical reviews of the current status of neutrino oscillations, and phenomenological studies on neutrino tomography and experimental studies to support nuclear matrix element calculations (NUMEN)
El folklore de Arenas de San Pedro y su repercusión en la educación musical. Propuestas educativas con el audiovisual
El presente artículo recoge la historia y el folklore de Arenas de San Pedro. Se realiza una fundamentación teórica y una aproximación a la música tradicional del pueblo. Así mismo, se ofrece una propuesta didáctica a través del audiovisual como recurso educativo, compuesta por fotografías históricas y actuales de la comarca, varios vídeos del grupo folklórico Los Pilaretes de Vettonia, imágenes de cada una de las partes del traje tradicional de la mujer y del hombre, y el texto de una selección de canciones y refranes de la tierra para trabajar en el aula de primaria
Supernova Neutrino Oscillations
Observing a high-statistics neutrino signal from a galactic supernova (SN)
would allow one to test the standard delayed explosion scenario and may allow
one to distinguish between the normal and inverted neutrino mass ordering due
to the effects of flavor oscillations in the SN envelope. One may even observe
a signature of SN shock-wave propagation in the detailed time-evolution of the
neutrino spectra. A clear identification of flavor oscillation effects in a
water Cherenkov detector probably requires a megatonne-class experiment.Comment: Proc. 129 Nobel Symposium "Neutrino Physics", 19-24 Aug 2004, Swede
Supernova neutrinos: production, propagation and oscillations
I shall review some of the recent results concerning the astrophysics of a
core collapse supernova (SN) and neutrino oscillations. Neutrinos play an
important role in the SN explosion, and they also carry most of the energy of
the collapse. The energy spectra of neutrinos and antineutrinos arriving at the
Earth incorporate information on the primary neutrino fluxes as well as the
neutrino mixing scenario. The analysis of neutrino propagation through the
matter of the supernova and the Earth, combined with the observation of a
neutrino burst from a galactic SN, enables us to put limits on the mixing angle
and identify whether the mass hierarchy is normal or inverted.
The neutrino burst also acts as an early warning signal for the optical
observation, and in addition allows us to have a peek at the shock wave while
still inside the SN mantle.Comment: 8 pages, uses espcrc2.sty (Nucl. Phys. B). Talk given at Neutrino
