What are particle physicists doing after finding the Higgs boson?

Finding the Higgs boson was the last piece in physicists' model of matter. But Tracey Logan discovers there's much more for them to find out at the Large Hadron Collider.

Finding the Higgs boson on July 4th 2012 was the last piece in physicists' Standard model of matter. But Tracey Logan discovers there's much more for them to find out at the Large Hadron Collider. To start with there is a lot of work to establish what kind of Higgs boson it is. 

Tracey visits CERN and an experiment called LHCb which is trying to find out why there's a lot more matter than anti-matter in the universe today. Dr Tara Shears of Liverpool University is her guide. 

Tracey also talks to physicists who are hoping to find dark matter in the debris of the collisions at the LHC. Scientists know there's plenty of dark matter in the universe, from its effects on galaxies, but they don't know what it is. Tracey discovers that this fact isn't stopping the particle physicists carrying out experiments.
