Axial anomaly through analytic regularization
(Modern Physics Letters A, 1999-01-30) [Artigo]
In this work we consider the two-point Green's functions in (1 + 1)-dimensional quantum electrodynamics and show that the correct implementation of analytic regularization gives a gauge invariant result for the vacuum ...
Causal theory for the gauged Thirring model
(European Physical Journal C, 1999-12-01) [Artigo]
We consider the (2 + 1)-dimensional massive Thirring model as a gauge theory, with one-fermion flavor, in the framework of the causal perturbation theory and address the problem of dynamical mass generation for the gauge ...
Testing anomalous Higgs couplings in triple photon production at the Tevatron collider
(Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 1998-09-10) [Artigo]
We derive bounds on Higgs and gauge-boson anomalous interactions using the CDF data for the process pp̄ → γγγ + X. We use a linearly realized SU L(2) X U Y(1) invariant effective Lagrangian to describe the bosonic sector ...
Three jet events and new strong couplings at LEP and NLC
(Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 1999-12-01) [Artigo]
We study the effects of new dimension-6 operators, resulting from a general SU(3)C ⊗ SU(2)L ⊗ U(1)Y invariant effective Lagrangian, on three jet production at LEP and at the Next Linear Collider. Contributions to the total ...
