      Physicists create string theory test

      PITTSBURGH, Feb. 1 Scientists have long questioned the validity of
      string theory and now U.S. physicists have created a test for the
      controversial theory of everything.String theory contends the
      fundamental forces and matter of nature can be reduced to tiny
      one-dimensional filaments called strings -- but no test exists for the
      predictions stemming from the premise.

      Now researchers at the University of California-San Diego, Carnegie
      Mellon University, and the University of Texas at Austin have developed
      a test that involves measuring how elusive high-energy particles scatter
      during particle collisions.

      Our work shows that, in principle, string theory can be tested in a
      non-trivial way, said Carnegie Mellon Professor Ira Rothstein. Some
      physicists believe such collisions will be observable at the Large
      Hadron Collider, a subatomic particle collider to begin operating later
      this year in Europe.

      Professor Jacques Distler of the University of Texas at Austin;
      Professor Benjamin Grinstein at University of California-San Diego,
      Carnegie Mellon graduate student Rafael Porto and Rothstein developed
      the test based on studies of how strongly force-carrying particles
      called W bosons scatter in high-energy particle collisions.

      The test is detailed in the Jan. 26 issue of the journal Physical Review
      Letters.
