Particle Physicists Rewrite Atomic Nature of Universe

An experiment led at the SLAC National Accelerator Laboratory suggests that the Standard Model, which describes how subatomic particles interact, may have some flaws. The researchers were looking for a particular decay process where B-bar mesons decay into three other particles: a D meson (a quark and an antiquark, one of which is “charm” flavored), an antineutrino (the antimatter partner of the neutrino) and a tau lepton (a cousin of an electron). What they found is that this process apparently happens more often than the Standard Model predicts it will. “If the excess decays shown are confirmed, it will be exciting to figure out what is causing it,” said BaBar physics coordinator Abner Soffer of Tel Aviv University.
