The LHC is back!

OK, so we’ve known this is coming for quite some time, but the largest physics experiment on Earth is now back up and running.

The Large Hadron Collider was switched on, with much fanfare, last year, but an electrical failure soon shut it down again. Teams at CERN have been working hard to get it back up and running and, on the 20th of November, issued a press release to inform the world that particles are once again accelerating around the collider.

Mention is made in the press release to a clockwise proton beam being established, while a recent tweet from CERN also makes mention of getting an anti-clockwise beam going. While this is all vital work CERN expect that the highest-energy particle collisions won’t occur until next year, although I’d be willing to bet there will be plenty of interesting information coming out of the various experiments around the LHC before then!

All of this leads up to the potential discovery of the Higgs Boson, a theoretical particle required to explain the presence of mass in the universe. Nobody knows for certain whether it exists (it’s predicted to exist but has never been observed) but by smashing protons together and seeing what they decay into the scientists at CERN hope to acquire evidence of the Higgs Boson’s presence.
