Computational model for electron–nucleon scattering and weak charge of the nucleon

We show how computational symbolic packages such as FeynArts, FormCalc, Form and LoopTools can be adopted for the evaluation of one-loop hadronic electroweak radiative corrections for electron-nucleon scattering and applied to calculations of the nucleon weak charge. Several numerical results are li...

Zusammenfassung:We show how computational symbolic packages such as FeynArts, FormCalc, Form and LoopTools can be adopted for the evaluation of one-loop hadronic electroweak radiative corrections for electron-nucleon scattering and applied to calculations of the nucleon weak charge. Several numerical results are listed, and found to be in good agreement with the current experimental data.
