Master Integrals for Fermionic Contributions to Massless Three-Loop Form Factors
In this letter we continue the calculation of master integrals for massless three-loop form factors by giving analytical results for those integrals which are relevant for the fermionic contributions proportional toN F , NF ·N , andNF /N . Working in dimensional regularisation, we express one of the integrals in a closed form which is exact to all orders in ǫ, containing Γ-functions and hyperge...
متن کاملCalculation of fermionic two-loop contributions to muon decay∗
The computation of the correction ∆r in the W-Z mass correlation, derived from muon decay, is described at the two-loop level in the Standard Model. Technical aspects which become relevant at this level are studied, e.g. gauge-parameter independent mass renormalization, ghost-sector renormalization and the treatment of γ5. Exact results for ∆r and the W mass prediction including O(α2) correctio...
متن کاملStrangeness contributions to nucleon form factors
We review a recent theoretical determination of the strange quark content of the electromagnetic form factors of the nucleon. These are compared with a global analysis of current experimental measurements in parity-violating electron scattering. PACS. 14.20.Dh Protons and neutrons – 11.30.Er Charge conjugation, parity, time reversal, and other discrete symmetries in particles and fields
متن کاملTwo-Loop QCD Corrections to the Heavy Quark Form Factors: Anomaly Contributions
We present closed analytic expressions for the order αs triangle diagram contributions to the matrix elements of the singlet and non-singlet axial vector currents between the vacuum and a quark-antiquark state. We have calculated these vertex functions for arbitrary momentum transfer and for four different sets of internal and external quark masses. We show that both the singlet and non-singlet...
متن کاملFermionic NNLO contributions to Bhabha Scattering
We derive the two-loop corrections to Bhabha scattering from heavy fermions using dispersion relations. The double-box contributions are expressed by three kernel functions. Convoluting the perturbative kernels with fermionic threshold functions or with hadronic data allows to determine numerical results for small electron mass m e , combined with arbitrary values of the fermion mass m f in the...
