By Damien Gayle PUBLISHED: 09:26 EST, 17 December 2012 | UPDATED: 12:03 EST, 17 December 2012 Scientists studying data from the the Large Hadron Collider who this summer announced the possible discovery of the Higgs boson now say they may have found two previously uknown particles. The most recent release from the Atlas experiment at the European Organisation for Nuclear Research (Cern) shows that their data contains two clear peaks indicating new particles. It seems they have found one Higgs boson with one mass, and then another with a statistically significant slightly higher mass. Scroll down for video

Latest release from Cern indicates that scientists have found two particles contending for the title of Higgs boson
@highlight
One has slightly more mass than the other, and each decays into different kinds of particles

Findings could challenge the Standard Model of physics, but researchers say they may merely be a statistical blip
The other 11 particles predicted by the model have been found - the @placeholder is the last jigsaw piece.
