Disappointment for LHC physicists

For six months, physicists at Cern's Large Hadron Collider near Geneva have been analysing an irregularity in the data coming from two of the machine's huge experiments.

The "bump" in the LHC results had the potential to revolutionise physics; it suggested the team may have detected an entirely new particle.

But as the experiments continued to run, the bump flattened - and eventually disappeared.

This footage comes from , a special edition of BBC2's Horizon programme tracking the search for the new particle.

Inside Cern will be broadcast on BBC2 at 20:00 on Wednesday 10 August.
