Physics of an Intense Neutrino Beam from BNL to a Very Long Baseline Detector

An intense neutrino facility allows probing of the neutrino mixing angles, mass hierarchy, and leptonic CP violation. Physics potential, for making precision measurements of all neutrino oscillation parameters (θij, Δmij2, δ) using a wide band νμ beam, to a (very long baseline) detector is presented. Potential of a Neutrino beam from Brookhaven National Laboratory to a 2540 km baseline (with 0.5 megaton) detector at Homestake Mine in South Dakota, is (under study by our neutrino working group) discussed. Schemaics of the beam facility for the AGS upgrade to 1 MW with a cycle time of 2.5 and 1014 protons on target at 28 GeV; and a map with possible detector sites are also included
