CP-odd WWZ couplings induced by vector-like quarks

Corrections to oblique parameters induced by anomalous vector boson couplings

We study quadratically divergent radiative corrections to the oblique parameters at CERN LEP1 induced by non-standard vector boson self-couplings. We work in the Stückelberg formalism and regulate the divergences through a gauge-invariant higher derivative scheme. Using consistency arguments together with the data we find a limit on the anomalous magnetic moment ∆κ of the W-boson, |∆κ| ∼< 0.26.

Higgs boson couplings to quarks with supersymmetric CP and flavor violations

In minimal supersymmetric model (SUSY) with a light Higgs sector, explicit CP violation and most general flavor mixings in the sfermion sector, integration of the superpartners out of the spectrum induces potentially large contributions to the Yukawa couplings of light quarks via those of the heavier ones. These corrections can be sizeable even for moderate values of tan β, and remain nonvanish...

Anomalous WWZ couplings and K L → μ + μ −

We study contributions to KL → μμ from anomalous WWZ interactions. There are, in general, seven anomalous couplings. Among the seven anomalous couplings, only two of them contribute significantly. The others are suppressed by factors like m2s/M 2 W , m 2 d/M 2 W , or m 2 K/M 2 W . Using the experimental data on KL → μμ, we obtain strong bounds on the two anomalous couplings.
