On the 1‐Loop Renormalization of the Electroweak Standard Model and its Application to Leptonic Processes

A renormalization scheme for the electroweak standard model is presented in which the electric charge and the masses of the gauge bosons, Higgs particle and fermions are used as physical parameters. The photon is treated such that quantum electrodynamics is contained as a simple substructure. Field renormalization respecting the gauge symmetry gives finite propagators and vertex functions. The Ward identities between the Green functions of the unphysical sector allow a renormalization that maintains the simple pole structure of the propagators in the t'Hooft‐Feynman gauge. We give a complete list of self energies and all renormalization constants also in the unphysical Higgs and ghost sector. Explicit results are given for the renormalized self energies, vertex functions and boxes that enter the evaluation of 1‐loop radiative corrections to fermionic processes. We calculate the 1‐loop radiative corrections to purely leptonic reactions like μ decay, vμμe scattering and μ pair production in e+e−annihilation. A test of the standard model is performed by comparing these low energy data with the results of the PP collider experiments for the W and Z boson masses.

The CHARM [8] and CCFR [9] experiments do not provide cross sections but only structure functions and hence their results are not included in our analysis.…”

A new global analysis of deep inelastic scattering data

View full text Add to dashboard Cite

A new QCD analysis of Deep Inelastic Scattering (DIS) data is presented. All available neutrino and anti-neutrino cross sections are reanalysed and included in the fit, along with charged-lepton DIS and Drell-Yan data. A massive factorisation scheme is used to describe the charm component of the structure functions. Next-to-leading order parton distribution functions are provided. In particular, the strange sea density is determined with a higher accuracy with respect to other global fits.Comment: 51 pages, 18 figure

“…As Figs. 8 and 9 indicate, finding N e − ≥ N µ + is sufficient to improve the bound roughly to ψ ≤ 0.02, an order of magnitude better than the bound inferred from [39]. Allowing |ψ eµ |= 0.025 has little effect on this statement.…”

“…We see again that looking for new physics may be quite fruitful in the comparisons of appearance signals in "pure" neutrino beams provided by muon colliders. The current direct limit on ψ µµ can be extracted from the limit [39] σ(ν µ + e − → µ − + ν)/σ(ν µ + e − → µ − + ν) = tan 2 ψ≤ 0.05, or tanψ ≤ 0.22. As Figs.…”

Revising neutrino oscillation parameter space with direct flavor-changing interactions

We formulate direct, neutrino flavor-changing interactions in a framework that fits smoothly with the parameterization of two-and three-state mixing of massive neutrino states. We show that even small direct interaction strengths could have important consequences for the interpretation of currently running and proposed oscillation experiments. The oscillation amplitude and the borders of the allowed regions in two-and three-flavor mixing parameter space can be sensitive to the presence of direct interactions when the transition probability is small. We use extensively the high sensitivity of the NOMAD experiment to illustrate potentially large effects from small, direct flavor violation. In the purely leptonic sector, we find that the clean νµ and νe beams from a µ + − µ − collider could provide the sharpest tests of direct flavor violation.
