Centre of Excellence for Particle Physics at the Terascale (CoEPP)

The ARC Centre of Excellence for Particle Physics at the Terascale (CoEPP) was established in 2011 through the award of an Australian Research Council grant of around $25 million over seven years.

The Centre is a collaborative research venture between The University of Melbourne, The University of Adelaide, The University of Sydney and Monash University. Each of the partner institutions contribute additional funding to the Centre, with The University of Melbourne hosting the head office.

Through the Centre, terascale high energy particle physics research across Australia is coordinated for the first time. Bringing together theoretical and experimental physicists, CoEPP also enables participation in the ATLAS experiment at the Large Hadron Collider at CERN in Geneva.  It greatly enhances linkages with partner international organisations in the field, expanding opportunities for Australian scientists and science students.

The aims of the LHC experiment, and those of CoEPP, are to discover answers to some of the fundamental questions in physics, questions that have until now been unanswerable. The enormous amounts of energy produced by the LHC particle accelerator will allow scientists to learn how particles gain mass, explore the identity of cosmological dark matter, and enable the discovery of new physical laws.

TPP Seminar: Light Stop Searches at the LHC in Events with two b-Jets and Missing Energy by Dr Jong Soo Kim (University of Adelaide)

Mon Nov 21 3:00pm - 4:00pm
Location: Nov 21 at 3pm in Geoff Opat Rm 360, the University of Melbourne

Abstract: We propose a new method to discover light top squarks (stops) in the co-annihilation region at the Large Hadron Collider (LHC). The bino-like neutralino is the lightest supersymmetric particle (LSP) and the lighter stop is the next-to-LSP. Such scenarios can be consistent with electroweak baryogenesis and also with dark matter constraints. We consider the production of two stops in association with two b-quarks, including pure QCD as well as mixed electroweak-QCD contributions. The stops decay into a charm quark and the LSP. For a higgsino-like light chargino the electroweak contributions can exceed the pure QCD prediction. We show the size of the electroweak contributions as a function of the stop mass and present the LHC discovery reach in the stop-neutralino mass plane.

TPP Seminar: Model building using Lie-point symmetries by Dr. Damien George (Nikhef, Amsterdam)

Tue Nov 22 3:15pm - 4:30pm
Location: Geoff Opat RM (360)

Dr.Damien George will discuss a technique that exhaustively determines all continuous symmetries of system, such as a set of coupled differential equations.  This technique has wide ranging applicability to theoretical physics, and he will detail its particular use in particle physics model building, where one is able to derive relationships between free parameters such that an enhanced symmetry is obtained.

iCHEP 2012

Wed Jul 4 9:00am - Wed Jul 11 5:00pm
Location: Melbourne

ICHEP (International Conference on High Energy Physics), often referred to as the Rochester Series, is the premier IUPAP-C11 conference in the field.
Held biannually, previous venues include Philadelphia, Moscow and Beijing and Paris. We have the support of University of Sydney, University of Adelaide, Canterbury University and the Australian Synchrotron, as well as that of many colleagues in the Asia-Pacific region and beyond. ICHEP2012 will be held in the Melbourne Convention Centre on the Yarra.  Initial LHC results will be beginning to mature, new results in neutrino physics are expected and dark matter searches are on our radar.

MEDIA RELEASE: CoEPP tackling the worldwide data deluge with assistance through NeCTAR eResearch tool

Published: 31/01/2012

ARC Centre of Excellence for Particle Physics at the Terascale (CoEPP) to share in $23 million eResearch funding through NeCTAR (National eResearch Tools and Resources)

CoEPP has made the list of NeCTAR (National eResearch Tools and Resources) preferred projects, announced on 23 January. The funding will assist the Centre to build both a National Cloud-based, general purpose, high throughput, data processing, simulation and analysis facility; and to enable its grid site to be deployed on the NeCTAR research cloud.

MEDIA RELEASE:Search results for Higgs boson yield tantalizing results

Published: 14/12/2011

Australian researchers from ARC Centre of Excellence for Particle Physics at the Terascale (CoEPP) play key role in the search for the Higgs Boson.

Last night at midnight the preliminary results of the ATLAS and CMS experiments were presented.

Their results are based on the analysis of data sufficient to make significant progress in the search for the Higgs boson, but not enough to make any conclusive statement on the existence or non-existence of the elusive Higgs.

Higgs bosons, if they exist, are very short lived and can decay in many different ways. Discovery relies on observing the particles they decay into rather than the Higgs itself. Both ATLAS and CMS have analysed several decay channels, and the experiments see small excesses in the low mass region that has not yet been excluded.

Tantalising hints have been seen in the ranges 116-130 GeV by the ATLAS experiment, and 115-127 GeV by CMS but these are not yet strong enough to claim a discovery.
