It can't be seen with the naked eye, and it requires the power of the world's largest and most complex machine to find.Yet it could change the very understanding of the known world of particle physics.Right now, it's simply a bump.
"In particle physics, a bump is when you have a smooth data curve—which is what you expect—and you see a little excess, a little bump in the middle of it, and that often is indicative that you may have made a discovery of some kind."
Don Lincoln is one of hundreds of scientists at Fermilab in suburban Chicago reviewing the data produced by LHC.
"Since about 1964, we have invented a series of theories that, blended together, is called the Standard Model of Particle Physics and from that we can explain all data that we've taken.However, we can't explain this bump."
Which means this "bump" could represent a new particle previously unknown to scientists.
"If it is real, it's probably the biggest discovery of the last half century."
Fermilab, is the home of the Tevatron accelerator, once the largest superconducting supercollider in the world.Though now offline, it eclipsed by CERN's LHC, Fermilab remains at the forefront of particle physics.
"We bring a certain amount of technology, know-how, to their machine because we started with a superconducting machine.So we have viable knowledge to bring to the table."
Fermilab's director, Nigel Lockyer says particle physics is now a more global exercise.
"We're into a new era of relationship between CERN and Fermilab, or between the United States and Europe, intertwining our particle physics programs."
What helps the interaction are technological advances and global cooperation that allow scientists at Fermilab to remotely monitor and analyze data produced by the LHC's particle collisions some 7,000 kilometers away.And with this latest potential discovery, Don Lincoln says there are two explanations.
"One is that this is just a random statistical fluctuation and it will disappear with more data, and we need to be very clear about that.However, in the far more exciting possibility is that if it is real, yes, absolutely it is a completely fascinating thing that will rewrite our understanding of how the world works."
The LHC starts a six-month run of proton-smashing collisions, scientists help to provide the answers to whether the "bump" is a new particle, or simply a bump in the road to better understanding the Standard Model of Particle Physics.
