Charm lifetimes and mixing

PDF Version Also Available for Download.

Description

A review of the latest results on charm lifetimes and D-mixing is presented. The e{sup +}e{sup -} collider experiments are now able to measure charm lifetimes quite precisely, however comparisons with the latest results from fixed-target experiments show that possible systematic effects could be evident. The new D-mixing results from the B-factories have changed the picture that is emerging. Although the new world averaged value of y{sub CP} is now consistent with zero, there is still a very interesting and favored scenario if the strong phase difference between the Doubly-Cabibbo-suppressed and the Cabibbo-flavored D{sup 0} {yields} K{pi} decay is large.
