Couplings between generalized gauge fields

We analyze the BRST field-antifield construction for generalized gauge fields consisting of massless mixed representations of the Lorentz Group and we calculate all the strictly gauge invariant interactions between them. All these interactions are higher derivative terms constructed out from the derivatives of the curl of field strength. PACS: 2.20.-a, 11.15.-q, 11.10.Kk, 11.25.-w

Gauge boson couplings at LEP

Self couplings among electroweak gauge bosons are a consequence of the non-Abelian structure of the Standard Model (SM) of electroweak interactions [1]. The measurement of triple (TGC) and quartic couplings (QGC) has been one of the main activities of the LEP experiments (ALEPH, DELPHI, L3 and OPAL) after the ee centreof-mass energy ( √ s) was raised above the threshold for the production of tw...

Minimal Gauge Invariant Classes of Tree Diagrams in Gauge Theories

We describe the explicit construction of groves, the smallest gauge invariant classes of tree Feynman diagrams in gauge theories. The construction is valid for gauge theories with any number of group factors which may be mixed. It requires no summation over a complete gauge group multiplet of external matter fields. The method is therefore suitable for defining gauge invariant classes of Feynma...

Gauge-Invariant Perturbations of Varying-Alpha Cosmologies

Using a gauge-invariant formalism we derive and solve the perturbed cosmological equations for the BSBM theory of varying fine structure ’constant’. We calculate the time evolution of inhomogeneous perturbations of the fine structure constant, δα α on small and large scales with respect to the Hubble radius. In a radiationdominated universe small inhomogeneities in α will decrease on large scal...

Gauge–invariant Charged, Monopole and Dyon Fields in Gauge Theories

We propose explicit recipes to construct the euclidean Green functions of gauge– invariant charged, monopole and dyon fields in four–dimensional gauge theories whose phase diagram contains phases with deconfined electric and/or magnetic charges. In theories with only either abelian electric or magnetic charges, our construction is an euclidean version of Dirac's original proposal, the magnetic ...
