CMS is one of the four particle physics experiments at the Large Hadron Collider (LHC) at CERN.

CMS is a particle detector designed to identify a wide range of particles and phenomena produced from high energy proton collisions at the LHC. The CMS experiment studies these collisions with the aim of better understanding particle interactions with respect to subjects such as the Higgs Boson and the origin of mass, dark matter and gravity.

The CMS experiment has been publishing physics results since the LHC began data taking in the summer of 2008. The highlight was the discovery of the Higgs boson at the same time as the ATLAS experiment in 2012.


The RAL PPD group has had the principal responsibility for the construction of the electromagnetic endcap calorimeter, and has played a major role in developing electronics and software for the CMS silicon tracker detector and in defining the CMS offline computing model.

The group comprises of experimentalist, theorist and students. The physics interests of the group include top physics, exotic bosons, long-lived particles, quantum black holes, exotic signatures with a ​boosted Z boson and exotic Higgs.​
