The Elusive Neutrino

After briefly introducing the neutrino the observations that led to the discovery of neutrino oscillations are described. Various sources of neutrinos have been used to uncover facets of neutrinos including the more recent measurement of one of key neutrino parameters in a reactor based experiment at Daya Bay, China. The Indian effort to build an underground laboratory for rare processes is outlined. The flagship experiment to measure atmospheric muon neutrinos and antineutrinos, separately, will target the open problem of ordering of the 3 tiny neutrino masses. Together with other experiments worldwide this will help address CP violation in the neutrino sector. This could help us understand why there is a preponderance of matter over anti-matter in the universe we live in.

Neutrino experiments: Status, recentprogress, and prospects", plenary talk at Intern. Europhys

Abstract. Neutrino physics has seen an explosion of activity and new results in the last decade. In this report the current state of the field is summarized, with a particular focus on progress in the last two years. Prospects for the near term (roughly 5 years) are also described. Introduction Neutrinos have been a focus of experimental effort over the last decade with old questions answered and new ones emerging. This review attempts to summarize the state of the field, highlighting progress made in the last two years (the time since the last EPS HEP conference), and outlining prospects for the near future. Of necessity many neutrino related areas have been omitted from this work, either because they are covered in other parts of the EPS HEP conference, because they are too futuristic to be considered prospects for the near term, or because time and page constraints do not allow complete coverage. In particular, theoretical developments and the physics of cosmic ray neutrinos are ...

Scientific Opportunities with the Long-Baseline Neutrino Experiment

In this document, we describe the wealth of science opportunities and capabilities of LBNE, the Long-Baseline Neutrino Experiment. LBNE has been developed to provide a unique and compelling program for the exploration of key questions at the forefront of particle physics. Chief among the discovery opportunities are observation of CP symmetry violation in neutrino mixing, resolution of the neutrino mass hierarchy, determination of maximal or near-maximal mixing in neutrinos, searches for nucleon decay signatures, and detailed studies of neutrino bursts from galactic supernovae. To fulfill these and other goals as a world-class facility, LBNE is conceived around four central components: (1) a new, intense wide-band neutrino source at Fermilab, (2) a fine-grained `near' neutrino detector just downstream of the source, (3) the Sanford Underground Research Facility (SURF) in Lead, South Dakota at an optimal distance (~1300 km) from the neutrino source, and (4) a massive liquid argon ...
