The phenomenology of [Formula: see text] mixing involves four parameters: average width Γ, mixing ratio |q|p|, mass difference proportional to x, and width difference proportional to y. We point out the types of experimental inputs that are eventually needed in order to determine the four parameters completely and in a model-independent way. For the sign of y we suggest the measurement (at ϒ(4S) factories) of a certain time-asymmetry when one of the neutral B mesons is tagged and the other decays to a CP-eigenstate. For the sign of x we propose similar time-asymmetries when one of the B mesons undergoes the chain decay: B→KJ/ψ, and the neutral kaon →πlν or π+π−.
Neutrino counting at e + e -colliders can be used to provide a limit on the magnetic moment of the .r neutrino. We obtain a limit of p < 5.6 X 1 0~~~~ at 90% C.L.
On p. 191, the sentence containing the very first displayed equation should be completed by adding the following after the semicolon: "we assume CPT invariance throughout, and take i8) =CPilB); we define the symbols mpmi On p. 192, in the equation displayed before Eq. (8), the expression [1 -Re(r;ri )] on the extreme right should read [1 -2 Re(r; rz* )]. .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
