After its much heralded re-start last year, has the world's biggest machine, the Large Hadron Collider, found a new particle?

You could be forgiven for thinking that things had gone a little quiet at Cern in Switzerland after the LHC was switched on to great fanfare in April 2015.

But physicists have been hard at work crunching data collected by the world's most powerful particle accelerator, which is now operating at unprecedented levels of energy and intensity.

Their efforts may not have been in vain, because there has been growing excitement in the hallways and offices at Cern in Geneva over a so-called "bump" in the data from the LHC's particle collisions.

The LHC smashes two beams of proton particles together about 100m beneath the French-Swiss border. Scientists then scour the debris of these smash-ups for hints of previously undiscovered particles.

iWonder: What will the LHC discover next?
