Available in PDF, EPUB and Kindle. Book excerpt: A feasibility study of the time evolution of a long-lived .nu./sub .mu./ beam was performed. The proton momentum (1.5 GeV/c) was chosen to concentrate the .nu./sub .mu./ flux at very low energy where all background reactions are kinematically suppressed. Sensitivity to oscillations at large proper times tau Varies as l/p (where l is the flight length and p is the momentum of the neutrino) is greatly enhanced by the resulting low neutrino momentum. Possible transformations .nu./sub .mu./ .-->. .nu./sub e/ (searched for via .nu./sub e/n .-->. e−p reactions) were not observed in an exposure of 2 x 1018 protons on target. Ten possible .nu./sub .mu./n .-->. .mu.−p events were observed. An upper limit of 3 eV, comparable to previous limits, can be placed on the mass difference between the two neutrino eigenstates. The accelerator backgrounds are low and the neutrino fluxes copious so that an experiment to approach a mass difference limit of less than or equal to 1 eV is currently possible. Future experiments with longer distances and larger masses could reach 0.1 eV at the AGS, comparable to the best limits proposed in other accelerator and reactor experiments. 34 references.

Book excerpt: We report on a search for neutrino oscillations of the type nu/sub .mu./ .-->. nu/sub e/ in a detector located an effective distance of 96m from the neutrino source in the wide band neutrino beam at the Brookhaven AGS. No excess of electron events was observed. The resulting upper limit on the strength of the mixing between nu/sub .mu./ and nu/sub e/ in the case of large mass difference .delta.m2 = absolute value m12 - m22 between the neutrino mass eigenstates m1 and m2 is sin22.cap alpha. less than or equal to 3.4 x 10−3 at 90% CL. The corresponding upper limit for small mass difference is .delta.m2sin2.cap alpha.

Available in PDF, EPUB and Kindle. Book excerpt: We have taken neutrino data with the Narrow Band Beam (NBB) at Brookhaven National Laboratory (BNL) in the summer and fall of 1985. We are in the process of completing the analysis of the NBB data. In this paper we present preliminary results of this analysis. We observe an anomalous appearance of electron neutrinos above the expected background. 3 refs., 16 figs., 3 tabs.

Book excerpt: This paper attempts to summarize the neutrino oscillation section of the Workshop on Future Directions in Particle and Nuclear Physics at Multi-GeV Hadron Beam Facilities. There were very lively discussions about the merits of the different oscillation channels, experiments, and facilities, but we believe a substantial consensus emerged. First, the next decade is one of great potential for discovery in neutrino physics, but it is also one of great peril. The possibility that neutrino oscillations explain the solar neutrino and atmospheric neutrino experiments, and the indirect evidence that Hot Dark Matter (HDM) in the form of light neutrinos might make up 30% of the mass of the universe, point to areas where accelerator-based experiments could play a crucial role in piecing together the puzzle. At the same time, the field faces a very uncertain future. The LSND experiment at LAMPF is the only funded neutrino oscillation experiment in the United States and it is threatened by the abrupt shutdown of LAMPF proposed for fiscal 1994. The future of neutrino physics at the Brookhaven National Laboratory AGS depends the continuation of High Energy Physics (HEP) funding after the RHIC startup. Most proposed neutrino oscillation searches at Fermilab depend on the completion of the Main Injector project and on the construction of a new neutrino beamline, which is uncertain at this point. The proposed KAON facility at TRIUMF would provide a neutrino beam similar to that at the AGS but with a much increase intensity. The future of KAON is also uncertain. Despite the difficult obstacles present, there is a real possibility that we are on the verge of understanding the masses and mixings of the neutrinos. The physics importance of such a discovery can not be overstated. The current experimental status and future possibilities are discussed below.

Download or read book Long Baseline Neutrino Oscillation Experiment at the AGS. Physics Design Report written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a design for a multi-detector long baseline neutrino oscillation experiment at the BNL AGS. It has been approved by the BNL-HENP-PAC as AGS Experiment 889. The experiment will search for oscillations in the[nu][sub[mu]], disappearance channel and the[nu][sub[mu]][leftrightarrow][nu][sub e] appearance channel by means of four identical neutrino detectors located 1, 3, 24, and 68km from the AGS neutrino source. Observed depletion of the[nu][sub[mu]] flux (via quasi-elastic muon neutrino events, [nu][sub[mu]]n[yields][mu][sup[minus]]p) in the far detectors not attended by an observed proportional increase of the[nu][sub e] flux (via quasi-elastic electron neutrino events, [nu][sub e]n[yields] e[sup[minus]]p) in those detectors will be prima facie evidence for the oscillation channel[nu][sub[mu]][leftrightarrow][nu][sub[tau]]. The experiment is directed toward exploration of the region of the neutrino oscillation parameters[Delta]m[sup 2] and sin[sup 2]2[theta], suggested by the Kamiokande and IMB deep underground detectors but it will also explore a region more than two orders of magnitude larger than that of previous accelerator experiments. The experiment will run in a mode new to BNL. It will receive the fast extracted proton beam on the neutrino target approximately 20 hours per day when the AGS is not filling RHIC. A key aspect of the experimental design involves placing the detectors 1.5 degrees off the center line of the neutrino beam, which has the important advantage that the central value of the neutrino energy ([approx] 1 GeV) and the beam spectral shape are, to a good approximation, the same in all four detectors. The proposed detectors are massive, imaging, water Cherenkov detectors similar in large part to the Kamiokande and IMB detectors. The design has profited from their decade-long experience, and from the detector designs of the forthcoming SNO and SuperKamiokande detectors.
