ABSTRACT
The three-gluon vertex is a basic object of interest in nonabelian gauge theory. At the one-loop level, it has been calculated and analyzed by a number of authors. Here we use the worldline formalism to unify the calculations of the scalar, spinor and gluon loop contributions to the one-loop vertex, leading to an extremely compact representation in terms of field strength tensors. We verify its equivalence with previously obtained representations, and explain the relation of its structure to the low-energy effective action. The sum rule found by Binger and Brodsky for the scalar, spinor and gluon loop contributions in the present approach relates to worldline supersymmetry.

    We study N= 1 supersymmetric U(N) gauge theory coupled to an adjoint scalar superfield with a cubic superpotential containing a multi trace term. We show that the field theory results can be reproduced from a matrix model whose potential is given in terms of a linearized potential obtained from...

    We consider gauge messenger models in which X and Y gauge bosons and gauginos are messengers of supersymmetry breaking. In simple gauge messenger models, all the soft parameters except μ and Bμ are calculated in terms of a single scale parameter MSUSY which is proportional to F / MGUT....

    We adapt “string-inspired” worldline techniques to one-loop calculations on orbifolds, in particular on the S1/ Z2 orbifold. Our method also allows for the treatment of brane-localized terms, or bulk-brane couplings. For demonstration, we reproduce the well-known result for the...

    Starting from a generic second-order Lagrangian (that describes the dynamics of an Abelian tensor gauge field of degree two and depends on two arbitrary real constants) we perform the Dirac analysis. This procedure determines the number of physical degrees of freedom and also a generating set of...

    Non-Abelian vector gauge theories, with gauge groups of the type U(1)×SU(n)×SU(n’)×···, have been formulated in terms of scalar singleton fields. Massless vector mesons appear as two-singleton states. The theory is a gauge theory already at the singleton level, and...

    We evaluate two-body decay modes of charginos in the Minimal Supersymmetric Standard Model with complex parameters (cMSSM). Assuming heavy scalar quarks we take into account all decay channels involving charginos, neutralinos, (scalar) leptons, Higgs bosons and Standard Model gauge bosons. The...

    Grand Unified Theories often involve additional Abelian group factors, apart from the standard model hypercharge, that generally lead to loop-induced mixing gauge-kinetic terms. In this letter, we show that at the one-loop level this effect can be avoided in many cases by a suitable choice of...

    We describe scalar and spinor fields on a noncommutative sphere starting from canonical realizations of the enveloping algebra A=U(u(2)). The gauge extension of a free spinor model, the Schwinger model on a noncommutative sphere, is defined and the model is quantized. The noncommutative version...
