From CERN: ICHEP 2010 conference highlights first results from the LHC

A candidate for production of a top quark pair in the CMS detector.
Geneva, 26 July 2010. First results from the LHC at CERN1 are being revealed at ICHEP, the world’s largest international conference on particle physics, which has attracted more than 1000 participants to its venue in Paris. The spokespersons of the four major experiments at the LHC – ALICE, ATLAS, CMS and LHCb – are today presenting measurements from the first three months of successful LHC operation at 3.5 TeV per beam, an energy three and a half times higher than previously achieved at a particle accelerator.

With these first measurements the experiments are rediscovering the particles that lie at the heart of the Standard Model – the package that contains current understanding of the particles of matter and the forces that act between them. This is an essential step before moving on to make discoveries. Among the billions of collisions already recorded are some that contain 'candidates' for the top quark, for the first time at a European laboratory.

From Fermilab: Fermilab experiments narrow allowed mass range for Higgs boson

Observed and expected exclusion limits for a Standard Model Higgs boson at the 95-percent confidence level for the combined CDF and DZero analyses.
Batavia, Ill. – New constraints on the elusive Higgs particle are more stringent than ever before. Scientists of the CDF and DZero collider experiments at the U.S. Department of Energy’s Fermilab revealed their latest Higgs search results today (July 26) at the International Conference on High Energy Physics, held in Paris from July 22-28. Their results rule out a significant fraction of the allowed mass range established by earlier experiments.

The Fermilab experiments now exclude a Higgs particle with a mass between 158 and 175 GeV/c2. Searches by previous experiments and constraints due to the Standard Model of Particles and Forces indicate that the Higgs particle should have a mass between 114 and 185 GeV/c2. (For comparison: 100 GeV/c2 is equivalent to 107 times the mass of a proton.) The new Fermilab result rules out about a quarter of the expected Higgs mass range.

Director's Corner
Paris and politics
Today's issue features a Director's Corner from Brian Foster, Global Design Effort European Regional Director.

I write this "Director's Corner" in my hotel room while attending the 35th International Conference in High Energy Physics in Paris — the most important event on the particle physics calendar. Barry Barish will write in more detail on the conference in future "NewsLines". I want to take advantage of the strong ILC showing at the Conference to highlight my talk in one of the parallel session on ILC "Governance".
