This illustration shows a an electron and positron
colliding, resulting in a B meson (not shown) and an antimatter B-bar
meson, which then decays into a D meson and a tau lepton as well as a
smaller antineutrino. In findings reported in June 2012, physicists from
the BaBar experiment found that such a decay process happens more often
than predicted by the Standard Model of physics. CREDIT: Greg Stewart, SLAC National Accelerator Laboratory |
The reigning theory of particle physics may be flawed, according to new evidence that a subatomic particle decays in a certain way more often than it should, scientists announced.
This theory, called the Standard Model, is the best handbook scientists have to describe the tiny bits of matter that make up the universe. But many physicists suspect the Standard Model has some holes in it, and findings like this may point to where those holes are hiding.
