Parametrization of the Kobayashi-Maskawa matrix
Journal Article

· Phys. Rev. Lett.; (United States)
The quark mixing matrix (Kobayashi-Maskawa matrix) is expanded in powers of a small parameter lambda equal to sintheta/sub c/ = 0.22. The term of order lambda/sup 2/ is determined from the recently measured B lifetime. Two remaining parameters, including the CP-nonconservation effects, enter only the term of order lambda/sup 3/ and are poorly constrained. A significant reduction in the limit on epsilon'/epsilon possible in an ongoing experiment would tightly constrain the CP-nonconservation parameter and could rule out the hypothesis that the only source of CP nonconservation is the Kobayashi-Maskawa mechanism.
