Message-ID: <427B3277.1040103@neutrino.kek.jp> Date: Fri, 06 May 2005 18:01:43 +0900 From: Koichiro Nishikawa <nishikaw@neutrino.kek.jp> Subject: [Fwd: April 2005 long-baseline neutrino newsletter] -------- Original Message -------- Subject: April 2005 long-baseline neutrino newsletter Date: Thu, 05 May 2005 11:13:32 -0500 From: Maury Goodman at Argonne <mcg@hep.anl.gov> To: LONGBNEWS@FNAL.GOV CC: MCG@hep.anl.gov Long-Baseline Neutrino News April 2005 *** NuSAG chairs The Neutrino Scientific Advisory Group will help the DOE and NSF decide which neutrino projects go forward, particularly reactor, accelerator long-baseline and double beta decay. The NuSAG chairs are Gene Beier from the University of Pennsylvania (geneb@hep.upenn.edu) and Peter Meyers from Princeton (meyers@princeton.edu). The makeup of the rest of the committee should be announced soon, followed by meetings, reports, etc. *** NOvA Stage One approval The Fermilab PAC recommended stage I approval for the NOvA long-baseline neutrino experiment, and Fermilab director Mike Witherell accepted this recommendation. Even though the approval is unconditional, the PAC gave NOvA a list of questions to answer in writing for its June Aspen meeting, as part of its continuing oversight of the experiment. NoVA is aiming for a start in FY07. *** NOvA Department In preparation for possible reviews, Fermilab is setting up a NOvA department. A new term at Fermilab is "BTeV refugee". *** Super-NOvA Is the name taken? Anyway, this is a specific idea for a second detector with a shorter baseline. By exploiting matter effects, the hierarchy could be determined with only the neutrino run, free of degeneracies, provided that L/E is the same. hep-ph/0504015 *** Super-T2K, or a Korean detector for JPARC Not the name used. Anyway, with a new detector in Korea, a 4 MW JPARC and 8 years of running, Hierarchy and CP can be measured. Ishitsuka et al. hep-ph/0504026; & Hagiwara et al. hep-ph/0504061 *** NuMI running The target is back in and MINOS is running again. A spare target is still available. *** MIPP running The Main Injector Particle Production Experiment's goal, among others, is to measure particle production rates useful for predicting NuMI event rates. So far they have 4.79 Million events on H, Be, C, Al and Bi with 5, 17, 30, 50 and 72 GeV. The plan is to use the spare NuMI graphite target in the first week of June and run with 120 GeV for a month or so, if its available. *** MIPP upgrade MIPP readout is currently limited to 60 Hz by the TPC. A chip upgrade could increase this by 2 orders of magnitude. This could be useful, among other things, for linear collider detector R&D. *** Atmospheric Neutrino meeting in Mumbai/Bombay before ICRC An atmospheric neutrino pre-meeting (to ICRC) will be held at IIT-Mumbai on August 1 and 2. Afterwards there will be a bus to ICRC in Pune. Details soon http://www.tifr.res.in/icrc2005/ *** Indian Neutrino Observatory - INO report INO had a meeting 1 May attended by various Lab directors from Indian institutes and collaborators where they formally handed over the proposal to build a magnetised iron calorimeter. The proposal is to build a 50 kton magnetised iron calorimeter to study the atmospheric neutrino oscillation, precision measurement of oscillation parameters, matter effect, mass hierarchy problem, CPT violation. During a 2nd phase, it could/would be a neutrino factory far detector. *** Do Super-Kamiokande staff emit solar neutrinos? In hep-ex/0504005, L. Bergman's "Correlating Nu Flux and Staff Presence in the Super-Kamiokande-I Experiment", an attempt was made to interpret why significant correlations were found only for midnight hours and hours around noon, but not for any other hours: when the sun-earth axis and the staff-detector axis coincided, the likelihood increased that staff neutrinos (if any) were counted - as solar neutrinos. As the author points out, "...one may reasonably argue the conjecture ... is far-fetched." *** Neutrinos in Quantum Diaries MINOS collaborator Debbie Harris is participating in Quantum Diaries, a Year of Physics Activity: http://interactions.org/quantumdiaries/bios/debbie_harris.html She was on the front page of Chicago area papers last week http://www.dailyherald.com/search/searchstory.asp?id=42329 *** All the nus that's fit to print -- MINOS in the NYT http://www.nytimes.com/2005/04/26/science/26neut.html *** Taup 2005 in Zaragosa Spain 10-14 September 2005 The ninth International Conference on Topics in Astroparticle and Underground Physics, TAUP 2005, will be jointly organized by the Gran Sasso National Labs (LNGS, Italy) and the University of Zaragoza, 10-14 Sep 2005. http://ezpc00.unizar.es/taup2005/ *** Notable New References (- web page at bottom for links) <-> G.
