EVERY AXION HAS ITS DAY Physicist Gray Rybka of the University of Washington in Seattle and colleagues have created a detector sensitive enough to potentially
find hypothetical dark matter particles called
axions.
The
findings, published April 20 in Physical Review Letters, exclude a small range of
axion - like particles that could have comprised about 4 percent of dark matter.
«If we don't
find the WIMP, theorists will just switch their bets to
axions,» says Peter Graham, a physicist at Stanford University.
Based on the published work, which draws on data collected from 2012 - 2015, the team has
found no evidence of solar
axions.
However, because
axions react so little — and the reactions they are likely to produce are so faint —
finding them is tricky.
Efforts in the 1980s to
find this particle, named the
axion by theorist Frank Wilczek, currently of the Massachusetts Institute of Technology, were unsuccessful, showing that their detection would be extremely challenging.
If
axions are
found, it would be a major discovery that could explain not only dark matter, but other lingering mysteries of the universe.
International research team evaluates measurements at the Paul Scherrer Institute and
finds new constraints on the
axion - gluon interaction strength...
