New upper limit to neutrino mass
- November 1999 news article from
"An international team of physicists has found a new upper
limit for the effective electron neutrino mass. According
to physicists from the Max Planck Institute for Nuclear
Physics in Heidelberg and the Kurchatov institute in Moscow,
the neutrino must have a mass of not more than 0.2 eV -
which is 2.5 million times smaller than the mass of the electron."
Physicists look to neutrino factory

lab in Tsukuba, which is on the east coast near Tokyo, and
detected some 250 km away at the Super-Kamiokande neutrino
observatory in central Japan."

Neutrinos may decay
- April 1999 news article from
"The observation of neutrino oscillations - and hence neutrino
mass - by the Super-Kamiokande experiment last year was one of
the major physics discoveries of the 1990s. However, a team of
US scientists is now proposing that the results can be explained
by a new phenomenon - neutrino decay. Their model can, they claim,
account for all neutrino anomalies with just three flavours of
neutrino and is consistent with all experimental results to date."
Super-Kamiokande finds neutrino mass
- June 1998 news article from
"A team of Japanese and American physicists claim to have
found evidence that neutrinos have mass. Experiments at the
Super-Kamiokande detector in Japan suggest a neutrino mass

of the electron."

- Solving the Solar Neutrino Problem
Arthur B. McDonald; Joshua R. Klein; David L. Wark

- The Sudbury Neutrino Observatory has solved a 30-year-old
mystery by showing that neutrinos from the sun change species
en route to the earth.
- Double or Nothing
Science News, July 6, 2002, pp. 10-12
- The confirmed observation of neutrino oscillation implies that
the particles have mass. That makes a nuclear process called
neutrinoless double beta decay theoretically possible. If the
process does occur, it would mean that neutrinos are Majorana
particles, which are their own antiparticles. Several experiments to
detect this process are being performed, but positive results
are still in doubt.
The Mass Question
Nature, February 28, 2002, pp. 969-971
- Very recent results from studies of neutrinoless double-beta
deca suggest that lepton number may be very slightly violated in
nature. Together with neutrino oscillation measurements, this implies
all three neutrinos have about the same mass. If so, there would be
important constraints on the origin of neutrino mass in grand
- The Unbearably Unstoppable Neutrino
Discover, August 2001, pp. 33-41
- Neutrinos are almost massless and hardly interact in any way
with "normal" matter -- yet they may make up a larger percentage
of the mass of the universe. Detecting and studying them is a
formidable engineering challenge.
- Detecting Massive Neutrinos
Edward Kearns, Takaaki Kajita, Yoji Totsuka
Scientific American, August 1999, pp. 64-71
- Neutrino oscillation -- the conversion of a neutrino of one
type into another -- implies neutrinos have mass. The Super-Kamiokande
experiment in Japan has detected convincing evidence that neutrino

- A variety of existing and future neutrino detectors not only

the investigation of cosmology through "neutrino astronomy".
- Neutrino Oscillations
Kenji Kaneyuki, Kate Scholberg
American Scientist, May-June 1999, pp. 222-231
- The phenomenon of neutrino oscillation (spontaneous conversion
among electron, muon, and tau neutrinos) appears to have been
confirmed by observations of neutrinos produced in cosmic ray
events. The result implies that neutrinos have mass (not
predicted by the Standard Model). This has significant implications
for cosmology and the "solar neutrino problem".

John N. Bahcall, Frank Calaprice, Arthur B. McDonald, Yoji Totsuka

- Three large new solar neutrino detectors are scheduled to

neutrinos generated by the Sun.
- Neutrino Oscillations and Solar Neutrinos
Lincoln Wolfenstein; Eugene W. Beier
Physics Today, July 1989, pp. 28-36
- Although the standard model assumes all neutrinos are massless,
grand unified theories predict a nonzero neutrino mass. Such masses
would be too small to measure directly, but the phenomenon of
neutrino oscillation can give information indirectly.
