Is CP Invariance Violation Indicated by Neutrino Oscillations?

On page 3 of the following pdf:
http://pdg.lbl.gov/2005/reviews/numixrpp.pdf

the paragraph after equation 13.12, there's a line that says:
"Thus, if U is not real, the neutrino... When CPT holds, any difference between these probabilities indicates a violation of CP invariance."

I don't understand how it should be a violation of CP invariance, and not CPT invariance that is violated.

It's correct, but confusing. When the author writes "any difference between these probabilities", by "these probabilities" he refers to the probabilities calculated in equation (13.8), not the probabilities calculated in (13.12).
 

Thread 'Toponium Discovered'

Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...

Thread 'Dirac-Delta from Normalization of Continuous Eigenfunctions'

I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
