    Document submitted to 18th J-PARC PAC meeting in May 2014. 50 pages, 41 figuresDocument submitted to 18th J-PARC PAC meeting in May 2014. 50 pages, 41 figuresDocument submitted to 18th J-PARC PAC meeting in May 2014. 50 pages, 41 figuresHyper-Kamiokande will be a next generation underground water Cherenkov detector with a total (fiducial) mass of 0.99 (0.56) million metric tons, approximately 20 (25) times larger than that of Super-Kamiokande. One of the main goals of Hyper-Kamiokande is the study of CPCP asymmetry in the lepton sector using accelerator neutrino and anti-neutrino beams. In this document, the physics potential of a long baseline neutrino experiment using the Hyper-Kamiokande detector and a neutrino beam from the J-PARC proton synchrotron is presented. The analysis has been updated from the previous Letter of Intent [K. Abe et al., arXiv:1109.3262 [hep-ex]], based on the experience gained from the ongoing T2K experiment. With a total exposure of 7.5 MW ×\times 107^7 sec integrated proton beam power (corresponding to 1.56×10221.56\times10^{22} protons on target with a 30 GeV proton beam) to a 2.52.5-degree off-axis neutrino beam produced by the J-PARC proton synchrotron, it is expected that the CPCP phase δCP\delta_{CP} can be determined to better than 19 degrees for all possible values of δCP\delta_{CP}, and CPCP violation can be established with a statistical significance of more than 3σ3\,\sigma (5σ5\,\sigma) for 7676% (5858%) of the δCP\delta_{CP} parameter space

    39 pages, 26 figures, submitted to PTEPHyper-Kamiokande will be a next generation underground water Cherenkov detector with a total (fiducial) mass of 0.99 (0.56) million metric tons, approximately 20 (25) times larger than that of Super-Kamiokande. One of the main goals of Hyper-Kamiokande is the study of CPCP asymmetry in the lepton sector using accelerator neutrino and anti-neutrino beams. In this paper, the physics potential of a long baseline neutrino experiment using the Hyper-Kamiokande detector and a neutrino beam from the J-PARC proton synchrotron is presented. The analysis uses the framework and systematic uncertainties derived from the ongoing T2K experiment. With a total exposure of 7.5 MW ×\times 107^7 sec integrated proton beam power (corresponding to 1.56×10221.56\times10^{22} protons on target with a 30 GeV proton beam) to a 2.52.5-degree off-axis neutrino beam, it is expected that the leptonic CPCP phase δCP\delta_{CP} can be determined to better than 19 degrees for all possible values of δCP\delta_{CP}, and CPCP violation can be established with a statistical significance of more than 3σ3\,\sigma (5σ5\,\sigma) for 76%76\% (58%58\%) of the δCP\delta_{CP} parameter space. Using both νe\nu_e appearance and νμ\nu_\mu disappearance data, the expected 1σ\sigma uncertainty of sin2θ23\sin^2\theta_{23} is 0.015(0.006) for sin2θ23=0.5(0.45)\sin^2\theta_{23}=0.5(0.45)

    Le Château de Pélicier, est situé au sein du territoire du Parc du Luberon et du site Natura 2000 FR9301542 sur la commune de Manosque. Il héberge une colonie de reproduction de Petit Rhinolophe (Rhinolophus hipposideros), chauve-souris menacée de disparition et protégée. Cette espèce cohabite dans ce gîte régulièrement avec le Murin à oreilles échancrées (Myotis emarginatus) et le Grand Rhinolophe (Rhinolophus ferrumequinum). L’Office national des forêts, propriétaire du bâtiment, s’est engagé, étant donné l’importance de l’enjeu, à dédier le site aux chauves-souris sur le long terme. Le Parc du Luberon et le Groupe chiroptères de Provence ont apporté leur aide technique et scientifique pour effectuer les aménagements permettant de maintenir et conforter cette maternité à Petit Rhinolophe. Les travaux ont été réalisés à l’automne 2012. Un suivi des effectifs et des pièces utilisées ainsi que de la température (paramètre clef pour cette espèce) a été effectué avant et après les travaux.The castle of Pélicier is located in the Parc naturel régional du Luberon (Luberon Regional Nature Park – PNRL) territory and inside the Natura 2000 area FR9301542, near Manosque city. It is a roost and a nursery for endangered and protected bats, essentially the Lesser Horseshoe bat (Rhinolophus hipposideros), with also the Geoffroy’s bat (Myotis emarginatus) and the Greater Horseshoe bat (Rhinolophus ferrumequinum). From now on, the owner, the Office national des forêts (National agency for forests - ONF), has dedicated the building to bats. It has been restored in 2012 thanks to funding, tecnical and scientific support of the PNRL and Groupe Chiroptères de Provence (Bats group from Provence - GCP). The ONF has redone the roof to prevent it from collapsing, with specific arrangements to welcome the bats. Survey of bats, way of use and follow-up of the temperatures (key parameter for Lesser Horseshoe bats’ births) were done before and after building work to adjust facilities

    Guía de estudio núm. 56. Julio Le Parc: luz en movimiento

    No full text
    En esta guía de estudio se lee una breve aproximación al origen del arte cinético y su desarrollo en Argentina y Venezuela, señalando la manera como este arte ha logrado transformar espacios públicos no convencionales mediante la experimentación con la luz y el involucramiento del espectador. Y es en este arte en el que se ubica el artista argentino Julio Le Parc, cuyas exploraciones de materiales y del espacio lo han convertido en un magnífico creador de experiencias cinéticas mediante la luz y el movimiento. Incluye imágenes de siete obras
