From July 6 2011, we will have an informal gathering for discussion with "wine and cheese"(free) after the seminar.
Last Update: 2 May 2012
Japanese version is here.
"The T2K is the neutrino oscillation experiment by using muon
neutrino beam produced by the accelerator complex JPARC and the water Cherenkov detector Super-Kamiokande located at 295 km distance. We searched for νμ→νe appearance signal in the data taken from January 2010 until March 2011, corresponding to an exposure of 1.43 x 1020 proton on target. The exposure is about five times larger than that of the previous report. In the seminar, the results of the search for νe appearance in the T2K experiment will be reported. The T2K is organizing two simultaneous seminars in KEK and ICRR , to report the new results. " Presented file (pdf, 26.2 MB) |
" Very High Energy gamma-ray astronomy is a newly emerging and very successful branch of astrophysics. Exciting results have been obtained by the current generation Imaging Atmospheric Cherenkov Telescope systems (IACTs), such as HESS, MAGIC and VERITAS. MAGIC is now the largest Cherenkov stereo telescope system worldwide, and is sensitive to gamma rays in the energy range from 25GeV to 10TeV due to its large 17m diameter dishes. Many scientific results have been achieved with MAGIC on galactic and extra-galactic sources. Among them, the first detection of pulsed gamma ray emission from the Crab pulsar at 25GeV, and the detection of gamma ray emissions from distant Active Galactic Nuclei, demonstrate the strong advantage and unique features of MAGIC with its low threshold energy setting. The new discoveries and scientific results with the current generation IACTs, mainly with MAGIC, are reviewed and future project CTA (Cherenkov Telescope Array Project) will be discussed. " |
" T2K is a long baseline neutrino oscillation experiment utilizing an intense neutrino beam produced at J-PARC and detected by Super-Kamiokande located at a distance of 295 km. The primary goal of T2K is to complete the leptonic flavor mixing picture by discovering the last unknown angle theta_13 and by precisely measuring the atmospheric neutrino parameters. T2K started physics data taking in January 2010. In this talk, the first results based on the data taken in the first half of 2010, demonstrating the performance of the experiment, will be presented. Prospects for achieving the ultimate discovery sensitivity will be shown. " |
