High-energy neutrino astrophysics

JG Learned, K Mannheim - Annual Review of Nuclear and …, 2000 - annualreviews.org
▪ Abstract High-energy (>100 MeV) neutrino astrophysics enters an era of opportunity and
discovery as the sensitivity of detectors approaches astrophysically relevant flux levels. We …

The next-generation liquid-scintillator neutrino observatory LENA

…, T Lachenmaier, I Lazanu, JG Learned… - Astroparticle …, 2012 - Elsevier
As part of the European LAGUNA design study on a next-generation neutrino detector, we
propose the liquid-scintillator detector LENA (Low Energy Neutrino Astronomy) as a …

[HTML][HTML] Cosmic neutrino pevatrons: A brand new pathway to astronomy, astrophysics, and particle physics

…, H Goldberg, D Hooper, A Kusenko, JG Learned… - Journal of High Energy …, 2014 - Elsevier
The announcement by the IceCube Collaboration of the observation of 28 cosmic neutrino
candidates has been greeted with a great deal of justified excitement. The data reported so …

Evidence for oscillation of atmospheric neutrinos

…, S Tasaka, JW Flanagan, A Kibayashi, JG Learned… - Physical review …, 1998 - APS
We present an analysis of atmospheric neutrino data from a 33.0 kton yr (535-day) exposure
of the Super-Kamiokande detector. The data exhibit a zenith angle dependent deficit of …

First results from KamLAND: evidence for reactor antineutrino disappearance

…, PW Gorham, G Guillian, JG Learned, J Maricic… - Physical review …, 2003 - APS
KamLAND has measured the flux of ν e’s from distant nuclear reactors. We find fewer ν e
events than expected from standard assumptions about ν e propagation at the 99.95% CL In a …

Observation of a neutrino burst in coincidence with supernova 1987A in the Large Magellanic Cloud

…, WR Kropp, JG Learned, JM LoSecco, J Matthews… - Physical Review Letters, 1987 - APS
… h period in which the observed neutrino burst was found came after our learning of the
detection of a neutrino signal by Hirata et al. at UT 7". 35. with an uncertainty of ~ 1 min. … J …

Measurement of neutrino oscillation by the K2K experiment

…, G Kume, Y Kuno, Y Kurimoto, T Kutter, J Learned… - Physical Review D, 2006 - APS
We present measurements of ν μ disappearance in K2K, the KEK to Kamioka long-baseline
neutrino oscillation experiment. One-hundred and twelve beam-originated neutrino events …

Measurement of neutrino oscillation with KamLAND: Evidence of spectral distortion

…, PW Gorham, G Guillian, JG Learned, J Maricic… - Physical review …, 2005 - APS
We present results of a study of neutrino oscillation based on a 766 ton/year exposure of
KamLAND to reactor antineutrinos. We observe 258 ν e candidate events with energies above …

Solar and hep Neutrino Measurements from 1258 Days of Super-Kamiokande Data

…, RW Ellsworth, S Tasaka, A Kibayashi, JG Learned… - Physical review …, 2001 - APS
Solar neutrino measurements from 1258 days of data from the Super-Kamiokande detector
are presented. The measurements are based on recoil electrons in the energy range 5.0–…

Indications of neutrino oscillation in a 250 km long-baseline experiment

…, M Kohama, Y Koshio, WR Kropp, JG Learned… - Physical Review Letters, 2003 - APS
The K2K experiment observes indications of neutrino oscillation: a reduction of ν μ flux together
with a distortion of the energy spectrum. Fifty-six beam neutrino events are observed in …
