Abstract
The quark mixing matrix (Kobayashi-Maskawa matrix) is expanded in powers of a small parameter equal to . The term of order is determined from the recently measured lifetime. Two remaining parameters, including the -nonconservation effects, enter only the term of order and are poorly constrained. A significant reduction in the limit on possible in an ongoing experiment would tightly constrain the -nonconservation parameter and could rule out the hypothesis that the only source of nonconservation is the Kobayashi-Maskawa mechanism.
