The discovery of an elementary particle that looked a lot like the electron, but had 3500 times its mass stunned most particle physicists three decades ago. Martin Perl, who received the 1995 Nobel ...

The giant Large Hadron Collider at CERN’s lab in Europe may be closed until 2015 but experiments will still be run there in the second half of this year on much smaller synchrotrons that examined the ...

For decades physicists have sought signs of misbehaving particles—evidence of subtle cracks in the “Standard Model” of particle physics, the dominant theory describing the most fundamental building ...

Charged leptons are a breed of elementary particle that comes in three masses: the lightweight electron, responsible for the electricity in our homes; the middle-weight muon; and the heavy tau. Two ...
