Physicists detect process even rarer than the long-sought Higgs particle


By Karen McNulty Walsh – The analysis efforts started two years ago and were carried out in particular by groups from Brookhaven, Lawrence Berkeley National Laboratory, Michigan State Univ. and Technische Universität Dresden, Germany.

“Only about one in 100 trillion proton-proton collisions would produce one of these events,” said Marc-André Pleier, a physicist at the U.S. Dept. of Energy’s Brookhaven National Laboratory.

“It’s like a fingerprint,” Pleier said. “We have a predicted fingerprint and we have the fingerprint we measure. If the fingerprints match, we know that the Higgs does its job of mass generation the way it should. But if it deviates, we know that some other physics mechanism is helping out because the Higgs alone is not doing what we expect.” more> http://tinyurl.com/n6gje2q
