Dispersive effects in D^0 - D^0 mixing
Physical Review D
(1986)
Abstract
We estimate the size of dispersive effects in hC =2 interactions and find that they represent in fact the dominant components of D -3 mixing. The box diagram is suppressed by several orders of magnitude due to the small values of light-quark masses. Crucial to this argument is a discussion of how the Glashow-Iliopoulos-Maiani mechanism works in the dispersive sector.Â
