The Large Hadron Collider will start operation again at a higher energy at the beginning of 2015. Join Professor Ben Allanach for an introduction to the machine, particle physics and the discovery of the Higgs boson. Standard theory predicts that the quantum fluctuations should make the Higgs boson much heavier than it is observed to be, but a speculative theory of particle physics (supersymmetry) explains why the quantum fluctuations are small. This theory predicts a host of new particles for the LHC to find.
There were a few small anomalies in LHC data already that can be interpreted as the production of certain supersymmetric particles. One of the predicted supersymmetric particles has the right properties to be the mysterious dark matter observed in the universe. Such interpretations are ready for further experimental testing next year.
This event is part of the 2015 Cambridge Science Festival. No booking needed, but please arrive in good time for the start of the talk.
