Research Director's Report
Optimal ILC physics performance at acceptable cost and risk
This month's Research Director's Report was written by Jim Brau, co-chair of the Worldwide Study and regional detector contact for the Americas.

A widely used example of the unique physics capability of the linear collider is the determination of the Higgs boson spin through the measurement of the Higgstrahlung threshold cross section. This plot from the simulation study of Dova, Garcia-Abia and Lohmann illustrates this.
Several years ago, the international community reached a widely held understanding that a linear collider will be needed to study the underlying physics of the new phenomena expected to be discovered at the Large Hadron Collider (LHC). More than 2700 scientists signed the 2003 statement "Understanding Matter, Energy, Space and Time: the Case for the Linear Collider." This statement expressed the world-wide consensus for a linear collider with the necessary features that would enable the excellent physics programme envisioned. It emphasised the understanding of the Higgs boson, and new discoveries beyond the Standard Model, with emphasis on the benefit of precision measurements and the interplay of LHC and the linear collider. Also expressed were the many cross connections between linear collider experiments, neutrino and quark studies, cosmological and astrophysical measurements, and high-energy nuclear physics.

The German way to the forum

Many different institutes and labs in Germany are involved in the development of a time projection chamber (TPC) for the ILD detector.
Some ideas are so good that you have to export them when you move from one country to the other. This is especially the case in a global project like the ILC, where three regions and people from all over the place work together to make sure that whatever the LHC will find, the next generation of particle accelerators can study in detail. So when theorist Gudrid Moortgat-Pick moved from Durham, UK, to Hamburg, Germany, she took the concept of the interdisciplinary linear collider forum with her to create it in Germany. The first meeting of the new working group took place at DESY in June.

Big science future for Australia
"...This collaboration will support exciting developments in Australian research and innovation, with projects proposed including development of [...] a linear collider, in which scientists will be able to probe, in finer detail, the discoveries of the Large Hadron Collider and in doing so, unlock the mechanisms of matter and how it was formed in the universe..."

Japan to provide funds towards the Super KEKB upgrade

The frontiers of particle physics. The KEK SuperB machine will help extend the intensity frontier
High-energy physics got a substantial boost last month when MEXT (Ministry of Education, Culture, Sports, Science and Technology), the Japanese ministry that supports high-energy physics at KEK, announced that it will appropriate 10 billion yen (around 110 million dollars) towards the upgrade of KEKB over the three years starting this fiscal year. This new investment is welcome news, as it both will further an especially productive research area (B physics) and more generally the 'intensity' frontier. Recent strategic plans for the future of particle physics have emphasised the importance of a multi-prong approach, with the main areas being the energy frontier with the LHC and hopefully a future linear collider, as well as the intensity frontier with one element being a SuperB factory, and emerging cross-disciplinary probes in experimental particle astrophysics, called the cosmic frontier.
