Abstract

If the geometry of space-time is \nc\nc, i.e. [xμ,xν]=iθμν[x_{\mu},x_{\nu}]=i \theta_{\mu \nu}, then \nc\nc \cpviolng\cpviolng effects may be manifest at low energies. For a \nc\nc scale Λθ1/22TeV\Lambda \equiv \theta^{-1/2} \leq 2 TeV, \cpviol\cpviol from \ncg\ncg is comparable to that from the Standard Model (SM) alone: the \nc\nc contributions to ϵ\epsilon and ϵ/ϵ\epsilon'/\epsilon in the KK-system, may actually dominate over the Standard Model contributions. Present data permit \ncg\ncg to be the only source of \cpviol\cpviol. Furthermore the most recent findings for g-2 of the muon are consistent with predictions from \ncg\ncg.
