A senior researcher at the Large Hadron Collider says a new particle could be detected this year that is even more exciting than the Higgs boson.

The accelerator is due to come back online in March after an upgrade that has given it a big boost in energy.

This could force the first so-called supersymmetric particle to appear in the machine, with the most likely candidate being the gluino.

The BBC's science correspondent, Pallab Ghosh reports.
