Strong-interaction contributions to one-loop leptonic processes.
We classify all strong interaction contributions to all four-lepton processes through one loop in electroweak SU2 x VI and to all orders in strong interactions. We show that those parts which are not reliably calculated in perturbative QCD are all related to a certain integral over the total cross section for e+e+ hadrons at low energies. We evaluate this integral for the most recent data and f...
متن کاملOne-loop corrections to three-body leptonic chargino decays
We calculate full one-loop corrections to the genuine three-body decays of the light chargino χ̃ 1 → χ̃01l ±νl in the Minimal Supersymmetric Standard Model. We find that the corrections to the decay width can be of the order of a few percent. We show also how radiative corrections affect energy and angular distributions of the final lepton.

متن کاملSuperstring One-Loop and Gravitino Contributions to Planckian Scattering
Corrections to the semiclassical approximation in nearly forward Planckian energy collisions are here reconsidered. Starting from the one-loop superstring amplitude, we are able to disentangle the first subleading high-energy contribution at large impact parameters, and we thus directly compute the one-loop correction to the superstring eikonal. By comparing this result with previous ones by Am...
متن کاملSupersymmetry relations between contributions to one-loop gauge boson amplitudes.
We apply ideas motivated by string theory to improve the calculational efficiency of one-loop weak interaction processes with massive external gauge bosons. In certain cases " supersymmetry " relations between diagrams with a fermion loop and with a gauge boson loop hold. This is explicitly illustrated for a particular one-loop standard model process with four-external gauge bosons. The supersy...
متن کاملGravitational Interaction to One Loop in Effective Quantum Gravity
We carry out the first step of a program conceived, in order to build a realistic model, having the particle spectrum of the standard model and renormalized masses, interaction terms and couplings, etc. which include the class of quantum gravity corrections, obtained by handling gravity as an effective theory. This provides an adequate picture at low energies, i.e. much less than the scale of s...
