Particle Physics Theory May Be Flawed

Misbehaving Particles Poke Holes in Reigning Physics Theory

An illustration showing an electron and positron colliding, resulting a stream of other particles, including an antimatter B-bar meson.
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.

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.
