Higgs makes for exotic couples
Today's issue features a guest essay by James Wells, a theorist working at CERN who specialises in physics beyond the Standard Model.

Much of the history of particle physics has been devoted almost exclusively to finding out what our bodies are made of. We first learned about protons and electrons and neutrons because they constitute the matter that makes up our bodies, and we learned of photons (light) because it interacts with our bodies when we see. Up and down quarks are the constituents of protons and neutrons, and they are held together by gluons, carriers of the strong force. Neutrons turn into protons through the weak force. Thus, everything we study has a close connection to our physical bodies. Even exotic particles, such as charm quarks or tau leptons are merely nearly exact copies of particles that make up our bodies: only their masses are different.

2008 Nobel Prize goes to particle physics

This year's Nobel Prize in physics was awarded to a Japanese-born American and two Japanese particle physicists: Yoichiro Nambu, professor emeritus at University of Chicago, for the discovery of the mechanism of spontaneous broken symmetry in subatomic physics, Makoto Kobayashi, professor emeritus at KEK and executive director of the Japan Society for the Promotion of Science, and Toshihide Maskawa, professor at Kyoto Sangyo University in Kyoto, for the discovery of the origin of the broken symmetry which predicts the existence of at least three families of quarks in nature.

...If supersymmetry exists, while some supersymmetric particles can be discovered with the LHC, to really understand them requires a new machine, a linear collider that will collide electrons and positrons. The development of such a machine, which is decades away, has begun as a truly international effort called the International Linear Collider, Breedon said in an e-mail interview.

Preparations for S1-global at the STF at KEK

High-power tests of the first installed cavity in July 2008
Research and development on superconducting radiofrequency (rf) cavities, cryomodules and operational units is at the core of our programme to develop the technologies, the best possible machine design and an implementation plan for the ILC. As a central part of that programme, KEK is carrying out an ambitious plan to build and operate a test linac with high-gradient superconducting cavities. It will serve as a prototype of the main linac systems for ILC. I recently had the opportunity to observe the installation, where testing of cavities in ILC prototype cryomodules for the first phase of the projected ILC test programme on the Superconducting rf Test Facility (STF) has recently started with all four cavities installed already. One cavity has successfully been powered to 28.5 MV/m, the rest will be powered soon.

Image of the Week

Last week's Director's Corner incorrectly attributed the ATF2 final doublet (pictured above) to LAPP in Annecy, France, only. In fact LAPP contributed the supports - the shiny aluminium parts - and the special long table upon which everything sits, and the doublets were assembled there. The two red quadrupoles, the two green sextupoles and a remotely-controllable high-precision three-axis magnet mover immediately under each magnet were contributed by SLAC, and the copper-coloured beam position monitors were contributed by Kyungpook National University in Daegu, South Korea. The final doublet will have four beam position monitors. The other picture in last week's Corner shows Junji Urakawa in front of another set of red quadrupoles the were designed at SLAC and made in China. We thank everybody who pointed this out and apologise for the error.
