Sub-atomic particles that defy standard model

Standard model explains most known behaviours.

The LHCb experiment at CERN's Large Hadron Collider show proton-proton collisions at the interaction point (far left) resulting in a shower of leptons and other charged particles. The yellow and green lines are computer-generated reconstructions of the particles' trajectories through the layers of the LHCb detector. Credit: CERN/LHCB Collaboration
