The ATLAS experiment is one of the general purpose detectors installed at the Large Hadron Collider (LHC). ATLAS is a collaboration of 174 institutes from 38 different countries. The ATLAS group at the University of Warwick officially joined the experiment in February 2012.

The Large Hadron Collider, located on the Swiss-French border, is the highest energy particle collider ever constructed. Currently operating with beams of protons at an energy of 6.5 TeV brought into collision at four points on the ring, which has a circumference of 27km. At one of these collision points the ATLAS experiment operates, collecting as much information as possible about the interactions.

The 2012 observation of a new particle in the search for the Higgs Boson created much excitement. ATLAS was one of two experiments involved in the search for this much sought after particle at the LHC and published a paper on the observation of a new particle. Over the coming years it will be necessary for the experiments to measure the properties of this new object.

The LHC began its Run 2 phase in 2015, with collisions at 13 TeV. This heralds the collection of large datasets at the energy frontier which will reveal the detailed properties of the Higgs boson and will enable the search for New Physics.

Research Interests

The Warwick ATLAS group is involved in a number of research activities including the study of the Higgs Boson decay to a pair of tau leptons. The measurement of each of the decay modes is necessary to confirm this new particle behaves like a Standard Model Higgs Boson. In 2014 the Warwick group played a major part in the discovery of this decay mode and followed this up with an important role in studying the CP properties in the Higgs to tau tau decay. We are active in searches for BSM Higgs scenarios and for exotic and boosted di-boson signatures.

In addition to these activities the Warwick group are also involved in a variety of detector performance tasks related to the trigger. The trigger, which consists of both hardware and software elements, is the part of ATLAS which decides if an event observed by the detector is kept for further processing. This is necessary given that in the duration of one second there are hundreds of millions of collisions out of which only a few hundred may be stored. Our involvement consists of general trigger configuration, measurement of the performance of the Muon trigger and development of new algorithms to handle the challenging and evolving environment of the typical collision.

The ATLAS detector will be upgraded with a new silicon detector and updated trigger system. We are responsible for the Quality Control of the silicon strip module detectors and for parts of the trigger core software restructuring and cost monitoring.
