T invariance of Higgs interactions in the standard model

摘要

In the standard model, the Cabibbo-Kobayashi-Maskawa matrix, which incorporates the time-reversal violation shown by the charged current weak interactions, originates from the Higgs-quark interactions. The Yukawa interactions of quarks with the physical Higgs particle can contain further complex phase factors, but nevertheless conserveT, as shown by constructing the fermionT transformation and the invariant Euclidean fermion measure.
