Abstract
This grant supports research activities in particle physics at the Large Hadron Collider, CERN, the construction and testing of a beamline to evaluate a technique for the collimation of a muon beam, and work aimed at developing new techniques for the construction of megatonne detectors for neutrinos. Exploiting the newly commissioned Compact Muon Solenoid detector at the LHC will bring greatly enhanced understanding of the 'Standard Model' of particle physics, particularly in the area of heavy-quark physics, searching for as yet undiscovered gauge bosons and supersymmetric particles, and ultimately shedding light on the mysterious 'Higgs' boson which is connected with the origins of mass. The experimental work on to producing a narrow beam of muons is an essential precursor to building intense beams of these particles which will be used, by their decay in flight, to provide intense beams of neutrinos to be detected in large (million tonne) detector systems. Studying in detail the properties of neutrinos will illuminate the matter/anti-matter asymmetry of our universe.

Geographic Reach | National |
Primary Audience | Public/other audiences |
Results and Impact | This exhibit showed the ideas behind the Higgs boson, and guided visitors through the physics, engineering and computing developments that have led to its discovery. Activities included: mass generation using magnets; operation of a table-top accelerator; handling of components from LHC detectors; and dice games that simulate particle-physics experiments. From badges given away to individual visitors we estimate about 5000 people (pre-booked school groups and 7-18 year-old children with parents/carers) came to the stand. Not yet known, activity took place last week. |

Results and Impact | The Exhibition is the Society's main public event of the year and is open to members of the general public as well as students and teachers, scientists, policymakers and the media. The "Higgs Boson" stand was one of the most visited during the exhibition. Over 2300 students and 260 teachers visited the exhibition, most of whom will have visited the Higgs Boson stand. Over 11000 visitors in total attended and we estimate well over half of these visited our stand (judged by number of items given away to visitors). A large number of visitors from the general public were enthused about the LHC, ATLAS & CMS experiments and the UK role in discovering the Higgs Boson. |
