One of the most fundamental questions yet to be answered is why we live in a matter dominated universe, when it is widely believed that in the Big Bang equal amounts of matter and antimatter were created. Experimental measurements and theory hint that almost all matter and antimatter would have annihilated each other leaving behind a residual amount of matter to form our universe. The mechanism that would have favoured matter against antimatter is called “CP violation”. The LHC beauty (LHCb) is an experiment set up to explore what happened after the Big Bang that allowed matter to survive and build the Universe we inhabit today. The experiment will investigate the slight differences between matter and antimatter by studying a type of particle called the ‘beauty quark’, or ‘b quark’.
In this short film, released online, Tara Shears explores the LHCb experiment which is based at the Large Hadron Collider facility at CERN and involves about 700 scientists from 52 institutions around the world.
LHCb – The Beauty Experiment is being shown as part of the 2012 European Science TV and New Media Festival at 16:45 on Saturday 14th July 2012, as part of the New Media Session. A full festival programme can be found here.
