Subatomic particles that appear to defy Standard Model points to undiscovered forces

Subatomic particles have been found that appear to defy the Standard Model of particle physics. The team working at Cern‘s Large Hadron Collider have found evidence of leptons decaying at different rates, which could possibly point to some undiscovered forces.
Publishing their findings in the journal Physical Review Letters, the team from the University of Maryland had been searching for conditions and behaviours that do not fit with the Standard Model. The model explains most known behaviours and interactions of fundamental subatomic particles, but it is incomplete – for example it does not adequately explain gravity, dark matter and neutrino masses.
Researchers say the discovery of the non-conforming leptons could provide a big lead in the search for non-standard phenomenon. The Standard Model concept of lepton universality assumes leptons are treated equally by fundamental forces.
