Trilinear anomalous gauge couplings and nonstandard fermionic couplings

Cp Violating Anomalous Trilinear Gauge Couplings From

We study the contributions of the CP violating anomalous WWγ interactions to b → sll. We obtain cutoff independent results on κ̃ and λ̃, by constructing an asymmetry for the process B → Kll, where the B and B̄ events are added. We show that a sample of 10 B → Kee events can yield a bound, |κ̃| < 0.42 at 90% C.L., which is much tighter than the recent constraint from D0. PACS number: 12.60Cn, 13.20....

Probing Trilinear Gauge Boson Couplings at Colliders

A direct measurement of the trilinear WW and WWZ couplings is possible in the pair production of electroweak bosons at e + e ? and hadron colliders. This talk addresses some of the theoretical issues: the parameterization of \anomalous couplings" in terms of form factors and eeective Lagrangians, the complementary information which can be obtained in e + e ? vs. hadron collider experiments, and...

Trilinear Gauge Couplings from γγ → W + W −

If there is no the Standard Model Higgs boson, the interaction among the gauge bosons becomes strong at high energies (∼ 1TeV). The effects of strong electroweak symmetry breaking could manifest themselves indirectly through the vertices as anomalous gauge boson couplings before they give rise to new physical states like resonances. Here a study of the measurement of trilinear gauge couplings κ...

Gauge Invariance and Anomalous Gauge Boson Couplings

Using the S–matrix pinch technique we obtain to one loop order, gauge independent γWW and ZWW vertices in the context of the standard model, with all incoming momenta off–shell. We show that the vertices so constructed satisfy simple QED–like Ward identities. These gauge invariant vertices give rise to expressions for the magnetic dipole and electric quadrupole form factors of the W gauge boson...
