CSSM
- Centre for the Subatomic Structure of
Matter formed as an ARC Special Research Centre in 1997
- To understand the quark structure of matter
from protons and neutrons to atomic nuclei and neutron stars (pulsars)
- This has made Adelaide a major
international player in subatomic physics
- hundreds of scientists from around the
world came here to work with our staff and students (and still do!)

Atmospheric Physics : Recent Highlights
- The development and application of radars to study the
structure and dynamics of the atmosphere and ionosphere from the ground to geospace. – SuperDarn Over-the-Horizon radar – Meteor wind radars – Boundary Layer and Stratospheric wind profiling radars
- The development and application of optical techniques,
including lidar, to study the thermal structure and dynamics of the middle and upper atmosphere.
- Atmospheric Radar Systems (ATRAD): spin-off company
selling radars to national and international customers.
- Collaboration with French colleagues on super pressure
balloon studies of waves in the Antarctic lower stratosphere and their role in the destruction of ozone.

A Very Brief History of Subatomic Physics
- 1995: Won national competition to host a National
Institute of Theoretical Physics (NITP)
- 1997: Awarded ARC Special Research Centre for the
Subatomic Structure of Matter (CSSM)
- 2009: CSSM re-invented as C2SSM
(Adelaide University’s Research Centre for Complex Systems and the Structure of Matter)
- 2011: Node of the ARC Centre of Excellence for
Particle Physics at the Terascale (CoEPP)
- Currently more than 40 staff and post-graduate
students including experimental participation in ATLAS
SLIDE 40
Page 40
A few achievements since 1997
- Students:
− 78 Graduate students 1997+ − 54 Honours students − 46 undergraduates involved in research projects
- Workshops:
− 35 Workshops and Conferences 1997+ − Including QNP 2000; Symmetries in Subatomic Physics; Light-cone 2005; Pacific Spin 2011; Lattice 2012 and ICHEP (in Melbourne) 2012
- Approx. 370 journal articles with more than

This is a wonderfully challenging and exciting time for subatomic physics The likely discovery of the Higgs boson constitutes the most exciting development in particle physics in almost 30 years We know enough to realize just how much there must still be to learn Through the CoEPP and CSSM Adelaide is ideally placed to play a major role in this field in the coming decade and beyond

Summary
Together these research programs represent a remarkable effort to explore Nature at its deepest levels while simultaneously contributing to the defense of our nation and the health of local industry. The University and the people of South Australia can be very proud indeed of the Discipline of Physics at the University of Adelaide.

Fundamental Test of Non-Perturbative QCD
- Strangeness contribution is a vacuum polarization
effect, analogous to Lamb shift in QED
- It is a fundamental test of QCD at long distances
where the force is really strong
