• The Fascinating Search For Rare W Decays

    Updated: 2010-01-30 11:03:26
    W bosons are amazingly interesting objects. Almost thirty years after their discovery -by Carlo Rubbia and his collaborators of the UA1 experiment at CERN- they continue to provide critical information on the theory of electroweak interactions. The front of particle physics has moved quite a bit further from 1983, and yet the weapons we use todat to try and conquer unexplored land have not changed much. Today I wish to summarize one particular search that has been done by the CDF experiment at the Tevatron proton-antiproton collider, one which tries to catch W bosons as they decay in a very uncommon way. read more

    Updated: 2010-01-29 02:10:24
    No. The WMAP team has just released a new set of papers based upon seven years of data from their experiment. For a summary of how this new data has sharpened some of their previous results, see the Cosmological Interpretation paper. They have also gone over claims by many groups to have found deviations [...]

  • Next-generation accelerators, neutrino research get boost with new test beam

    Updated: 2010-01-27 14:53:40
      Fermilab has taken a major step toward laying the technical groundwork for Project X by creating a new test beam for superconducting radiofrequency cavities and components. Earlier this month, the High Intensity Neutrino Source (HINS) collaboration successfully accelerated a proton beam to 2.5 MeV in a radiofrequency quadrupole accelerator, or RFQ, for the first time at [...]

  • Ground-breaking neutrino R&D gets government boost

    Updated: 2010-01-14 09:47:05
    Work toward the world’s most intense long-distance neutrino beam received key government approval last week, invigorating US and global collaborators. The Long Baseline Neutrino Experiment passed the first Department of Energy approval stage Friday, Jan. 8, when it received Critical Decision-0. This designation cements the DOE’s support for the need and physics goals of the experiment. [...]

  • Newswire: STFC - Quantum leap for ISIS second target station

    Updated: 2010-01-08 06:00:00
    First published science results from new UK neutron source support Newton's ideas and quantum theory. Scientists have used the UK's newest major science facility to finally make the connection between the reflection of particles and waves as required by quantum mechanics. The phenomenon is a long established theory, but has not until now been seen. The result is the first to be published from the £200 million second target station recently opened at the ISIS Neutron Source in Oxfordshire and appears online today (January 8 2010) at Physical Review Letters. Whilst the discovery currently lies in the realm of pure physics, these results may initiate new developments in electronics, complementing the wave equivalent already used for photonics and metrology.

  • More Physics Questions

    Updated: 2009-12-29 16:29:37
    The turnaround of the three physics questions I offered a few days ago, to stimulate your neurons and extract you from the chocolate and alcohol flood caused by the usual string of Christmas parties and dinners, was rather scarce. Despite that, I wish to repeat the offer today, making some adjustments to reach a wider public. The questions I offer here are easier but still not accessible to everybody. However, my plans are that at least the answers I will give in a couple of days will be understandable. Further, anyone can try the bonus question I ask at the bottom of this piece... read more

  • Newswire: CERN - LHC ends 2009 run on a high note

    Updated: 2009-12-18 06:00:00
    Geneva, 18 December 2009. At its 153rd session today, the CERN[1] Council heard that the Large Hadron Collider ended its first full period of operation in style on Wednesday 16 December. Collisions at 2.36TeV recorded since last weekend have set a new world record and brought to a close a successful first run for the world's most powerful particle accelerator. The LHC has now been put into standby mode, and will restart in February 2010 following a short technical stop to prepare for higher energy collisions and the start of the main research programme.

    Updated: 2009-12-14 06:00:00
    Geneva, 14 December 2009 Medical studies are soon to start with the MARS scanner, a revolutionary CT scanner developed by the University of Canterbury[1], New Zealand. The scanner, which incorporates technology developed at the world's leading particle physics research centre, CERN[2], was recently shipped to research partners in North America. Today a student from Canterbury arrives in North America to use the scanner to study heart disease. This development puts the technology, known as Medipix[3], firmly on the path to saving lives.
