Negative contributions to S in an effective field theory
We show that an effective field theory that includes non-standard couplings between the electroweak gauge bosons and the top and bottom quarks may yield negative contributions to both the S and T oblique radiative electroweak parameters. We find that that such an effective field theory provides a better fit to data than the standard model (the χ per degree of freedom is half as large). We exami...
متن کاملGauge Anomalies in an Effective Field Theory*
A four-dimensional gauge theory with anomalous fermion content can be consistently quantized, provided that at least some gauge fields are permitted to have nonvanishing masses. Such a theory is nonrenormalizable; there is a maximal value of the ultraviolet cutoff ,4. beyond which the locality of the theory breaks down. The maximal ,4 can be estimated in perturbation theory and has a qualitativ...
متن کاملQuartet S Wave Neutron Deuteron Scattering in Effective Field Theory
The real and imaginary part of the quartet S wave phase shift in nd scattering (S3/2) for centre-of-mass momenta of up to 300 MeV (Ecm ≈ 70 MeV) is presented in effective field theory, using both perturbative pions and a theory in which pions are integrated out. As available, the calculation agrees with both experimental data and potential model calculations, but extends to a higher, so far unt...
متن کاملIntroduction to effective field theory
The basic idea behind effective field theory (EFT) methods is to describe nature in terms of a fully consistent quantum field theory, but one which is valid in a limited energy range. Now strictly speaking this means that almost any theory is an EFT except string theories that try to be a theory of everything (TOE). Indeed even the quintessential quantum field theory—quantum electrodynamics—is ...
متن کاملAn Introduction to Few Nucleon Systems in Effective Field Theory
Progress in the Effective Field Theory of two and three nucleon systems is sketched, concentrating mainly on the low energy version in which pions are integrated out as explicit degrees of freedom. Examples given are: the extraction of nucleon polarisabilities from deuteron Compton scattering at very low energies; the energy dependence of the nucleon polarisabilities; three body forces and the ...
