Abstract: "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 muon neutrinos which is inconsistent with expectations based on
calculations of the atmospheric neutrino flux. Experimental biases and
uncertainties in the prediction of neutrino fluxes and cross sections are
unable to explain our observation. The data are consistent, however, with
two-flavor V(mu) <--> V(gamma) oscillations with sin(squared)20 >
0.82 and 5 x 10(to the negative fourth) < 6 x 10(to the negative third)
eV(squared) at 90 confidence level."
This 1998 report from Physical Review
Letters describes neutrino-hunting research at the Super-Kamiokande
detector in Japan--a giant tank of water lined with thousands of sensing
phototubes, located 1,000 meters underground in an old silver mine. The paper
was cited 70 times in current journal articles processed in the
ISI database during July-August 2000. For the fourth bimonthly citation count
in a row, thanks to that figure, this paper bested all its rivals in physics
published in the last two years (aside from reviews). As of the next bimonthly
count (for September/October 2000) this paper, published in August of '98,
will exceed the Hot Papers two-year age limit, thereby becoming too
"old" for further coverage. But it certainly goes out on top. Prior
to the most recent bimonthly count, citations to the paper have accrued as
follows:
May-June 2000: 62 citations
March-April 2000: 56
January-February 2000: 32
November-December 1999: 42
September-October 1999: 38

May-June 1999: 25
