γee and its relation to CP and chiral tests
نویسنده
چکیده
The decay KL → πγee occurs at a higher rate than the nonradiative process KL → πee, and hence can be a background to CP violation studies using the latter reaction. It also has an interest in its own right in the context of chiral perturbation theory, through its relation to the decay KL → πγγ. The leading order chiral loop contribution to KL → πγee, including the (qe+ + qe−) 2/m2π dependence, is completely calculable. We present this result and also include the higher order modifications which are required in the analysis of KL → πγγ.

We have previously analysed the chiral predictions for the decay KL → π γee and discussed how experimental measurements of this process can help our understanding of chiral theories and of CP tests. Motivated by the possibility that the analogous muonic process may soon be measurable, we extend this calculation to the decay KL → π γμμ.

متن کاملGinsparg-Wilson operators and a no-go theorem
If one uses a general class of Ginsparg-Wilson operators, it is known that CP symmetry is spoiled in chiral gauge theory for a finite lattice spacing and the Majorana fermion is not defined in the presence of chiral symmetric Yukawa couplings. We summarize these properties in the form of a theorem for the general GinspargWilson relation. The Ginsparg-Wilson relation[1] provides a convenient fra...
متن کاملCP breaking in lattice chiral gauge theory
Discovery of gauge covariant local lattice Dirac operators [1,2], which satisfy the GinspargWilson relation [3], paved a way to a manifestly local and gauge invariant lattice formulation of anomaly-free chiral gauge theories [4]–[8]. (See also related early work in ref. [9]) It has been however pointed out that the CP symmetry, the fundamental discrete symmetry in chiral gauge theories, is not ...
