Reducing full one-loop amplitudes to scalar integrals at the integrand level
We show how to extract the coefficients of the 4-, 3-, 2and 1-point one-loop scalar integrals from the full one-loop amplitude of arbitrary scattering processes. In a similar fashion, also the rational terms can be derived. Basically no information on the analytical structure of the amplitude is required, making our method appealing for an efficient numerical implementation. e-mail: ossola@inp....
متن کاملOne loop scalar functions in the heavy quark effective theory
Since its early applications [1] the heavy quark symmetry has been one of the key ingredients in the theoretical investigations of hadrons containing a heavy quark. It has been successfully applied to the heavy hadrons spectroscopy, to the inclusive as well as to a number of exclusive decays (for reviews of the heavy quark effective theory and related issues see [2] or [3]). To describe interac...
متن کاملScalar one-loop integrals for QCD
We construct a basis set of infra-red and/or collinearly divergent scalar oneloop integrals and give analytic formulas, for tadpole, bubble, triangle and box integrals, regulating the divergences (ultra-violet, infra-red or collinear) by regularization in D = 4− 2ǫ dimensions. For scalar triangle integrals we give results for our basis set containing 6 divergent integrals. For scalar box integr...
متن کاملOne - loop renormalisation of N = 12 supersymmetric gauge theory in the adjoint representation
1 2 supersymmetric gauge theory coupled to chiral matter in the adjoint representation, and investigate the one-loop 1 2 supersymmetric theories (i.e. theories defined on non-anticommutative super-space) have recently attracted much attention[1]–[4]. Such theories are non-hermitian and only have half the supersymmetry of the corresponding N = 1 theory. These theories are not power-counting reno...
متن کاملAmplitudes for massive vector and scalar bosons in spontaneously-broken gauge theory from the CHY representation
In the formulation of Cachazo, He, and Yuan, tree-level amplitudes for massless particles in gauge theory and gravity can be expressed as rational functions of the Lorentz invariants ka · kb, ǫa · kb, and ǫa · ǫb, valid in any number of spacetime dimensions. We use dimensional reduction of higher-dimensional amplitudes of particles with internal momentum κ to obtain amplitudes for massive parti...
