CP violation from noncommutative geometry -: art. no. 116007

If the geometry of space-time is noncommutative, i.e,, [x(mu),x(nu)]=i theta (mu nu), then noncommutative CP violating effects may be manifest at low energies. For a noncommutative scale Lambda = theta (-1/2)less than or equal to2 TeV, CP violation from noncommutative geometry is comparable to that from the standard model alone: the noncommutative contributions to epsilon and epsilon'/epsilon in the K system may actually dominate over the standard model contributions. Present data permit noncommutative geometry to be the only source of CP violation. Furthermore the most recent findings for g-2 of the muon are consistent with predictions from noncommutative geometry.
