19 November 2012 - BaBar Experiment Confirms Time Asymmetry
Interactions NewsWire #91-12 19 November 2012 http://www.interactions.org ******************************************* Source: SLAC National Accelerator Laboratory Content: Press Release Date Issued: 19 November 2012 ******************************************* Time's quantum arrow has a preferred direction, new analysis shows Menlo Park, Calif. — Time marches relentlessly forward for you and me; watch a movie in reverse, and you'll quickly see something is amiss. But from the point of view of a single, isolated particle, the passage of time looks the same in either direction. For instance, a movie of two particles scattering off of each other would look just as sensible in reverse – a concept known as time reversal symmetry.
We were all transfixed by the Higgs seminars on July 4 , but the work was nowhere near over for the experimentalists — they had to actually write up papers describing the results. And of course taking the opportunity to do a little more analysis along the way. Now the papers have appeared on the arxiv.
