Physics and detectors at TILC09
This month's Research Director's Report was written by Hitoshi Yamamoto, co-chair of the Worldwide Study and regional detector contact for Asia.
Conference venue for TILC09: Epochal Tsukuba |
I am writing this column for the first time as one of the three regional contacts who serve under the ILC research director Sakue Yamada, but also as a co-chair of World Wide Study (WWS) and a member of the Asian Committee for Future Accelerators (ACFA. There will be a joint ACFA Physics and Detector Workshop and GDE Meeting (TILC09 – where 'T' stands for Tsukuba) from 17 to 21 April. The venue is a conference centre called EPOCHAL Tsukuba located in the central part of the city of Tsukuba. In 1985, an international exhibition was also held around this location, and KEK is about 10 kilometres to the north. In this note, let us focus on the physics and detector part of the workshop since the accelerator part has been covered in the Director's Corner of February 19.

Fermilab experiments constrain Higgs mass
Scientists from the CDF and DZero collaborations combined Tevatron data from their two experiments to increase the sensitivity for their search for the Higgs boson. While no Higgs boson has been found yet, the results announced today exclude a mass for the Higgs between 160 and 170 GeV/c² with 95 percent probability. Image: Fermilab.

Life after the LOI
SiD Workshop at SLAC

A Silicon Detector (SiD) workshop was held at SLAC from 2 to 4 March, with the express purpose of reviewing the status of the SiD Letter of Intent, organising the final steps in its completion, and beginning to think of life after the LOI.
Persis Drell, the SLAC Director, opened the meeting by welcoming the collaboration to SLAC, and restated her firm conviction that the science case for the linear collider was as strong as ever. She noted shortcomings in the present US strategy to realise the ILC, and committed to working with others towards a remedy. Barry Barish followed Persis with a review of the Global Design Effort's considerable technical progress and a renewed commitment to be ready with a strong proposal to funding agencies in 2012.

Particle oddball surprises CDF physicists at Fermilab
Batavia, Ill.--Scientists of the CDF experiment at the Department of Energy's Fermi National Accelerator Laboratory announced yesterday (March 17) that they have found evidence of an unexpected particle whose curious characteristics may reveal new ways that quarks can combine to form matter.

Fermilab experiments constrain Higgs mass
To increase their chances of finding the Higgs boson, the CDF and DZero scientists combine the results from their separate analyses, effectively doubling the data available.

EU needs 'brutal' science advice
... In Europe, the body that provides scientific support to the commission is the Joint Research Centre, which Professor Beddington describes as "excellent". But it was unable to provide the proactive and sometimes "brutal" scientific advice that policy makers might not want to hear, he told BBC News.

Science in the Obama era

“We will restore science to its rightful place,” said President Barack Obama in his inauguration address. That statement has raised the hopes of the scientific community, and actions that have followed have further encouraged us to believe that we are entering a new era in the US that will have increased priority for the support of science. On the other hand, the most important problem in the US and worldwide is to deal with the deep economic downturn and the early actions by the new administration are dominantly aimed at dealing with this economic crisis and include a very large stimulus bill. In addition to economic stimulus, early decisions by the Obama administration have included appointing a number of highly regarded scientists to key high-level government positions. It is worthwhile anticipating how all the changes will impact US science, high-energy physics, in particular, and finally on our efforts towards the ILC.

Correction
Last week's feature on electron cloud work done at CERN caused confusion over the spacing of the beam screens and the spacing of the screens' sawteeth. The original text wrongly stated that the "beam screens protecting the superconducting magnets along the path of the beam every 300 micrometres, for example, have teeth (or grooves) that stop the photons, suppress photon reflections, and thus stop electrons getting knocked out above or below the beam." In fact it's the 30-micrometer teeth that are spaced at 500 micrometres from each other on every screen. These screens, installed in the 80 percent of the LHC that are cold (heat load being less of an issue in the 20 percent of the ring that are warm), uniformly cover the entire inner surface along the cold LHC arcs. ILC NewsLine apologises for any cloudiness this may have caused.
