"Large mass hierarchy from a small
extra dimension," by Lisa Randall and Raman Sundrum, Physical
Review Letters, 83(17):3370-3, 25 October 1999.

Abstract: "We propose a new higher-dimensional mechanism for
solving the hierarchy problem. The weak scale is generated from the Planck
scale through an exponential hierarchy. However, this exponential arises not
from gauge interactions but from the background metric (which is a slice of
AdS5 spacetime). We demonstrate a simple explicit example of this mechanism
with two 3-branes, one of which contains the standard model fields. The
phenomenology of these models is new and dramatic. None of the current
constraints on theories with very large dimensions apply."
This 1999 report from Physical Review
Letters was cited 56 times in current journal articles indexed in the
ISI database during March-April 2001. Only one other physics paper published
in the last two years (excluding reviews) received a greater number of
citations during that two-month period--a paper by the same pair of authors.
Randall and Sundrum, in other words, now account for the two hottest papers in
physics. Prior to the most recent bimonthly count, citations to the above
paper have accrued as follows:
January-February 2001: 37 citations
November-December 2000: 46
September-October 2000: 52
July-August 2000: 39
May-June 2000: 12
March-April 2000: 16
January-February 2000: 3
November-December 1999: 1
Total citations to date: 262

Papers Database (Available from the ISI
Research Services Group in a CD-ROM version containing data on
hundreds of highly cited papers published during the last two years.
User interface permits searching by author, organization, journal,
field, and more. Total citations, as well as citations accrued during
successive bimonthly periods, can be assessed and graphed. Database is
combined with subscription to the ISI newsletter Science
Watch®; updated discs containing the
most recent bimonthly data are mailed with each new issue, six times a
year.)
