In a paper published by physicists at the Fermilabs Tevatron particle accelerator in Illinois, researchers claim to have found evidence for a new fundamental particle outside the traditional Standard Model of Particle Physics that may represent a fifth fundamental physical force beyond gravity, electromagnetism, strong, and weak nuclear forces.
The paper, titled Invariant Mass Distribution of Jet Pairs Produced in Association with a W boson in ppbar Collisions at sqrt(s) = 1.96 TeV (arXiv:1104.0699v1 [hep-ex]), is a reporting of findings from a research project involving the smashing together of protons and antiprotons in an attempt to create new particles. The paper shows some results that are not predicted by the existing Standard Model of Particle Physics, and which (if confirmed) would mean that theory would need to be revised or thrown out altogether.
