The role of sigma(e+e- -> hadrons) in precision tests of the Standard Model
F. Jegerlehner
I present a summary of recent developments as they have been discussed in the many interesting contributions to the workshop SIGHAD03 at Pisa.
O(αα_s) relation between pole- and MS-mass of the t-quark
F. Jegerlehner, M. Yu. Kalmykov
The O(αα_s) contribution to the relationship between the MS- and the pole-mass of the t-quark propagator within the Standard Model is reviewed. At the same order also the correctio…
Theoretical precision in estimates of the hadronic contributions to (g-2)_mu and alpha_QED(M_Z)
F. Jegerlehner
I review recent estimates of the non-perturbative hadronic vacuum polarization contributions. Since these at present can only be evaluated in terms of experimental data of limited…
Isospin violating effects in e+e- vs. tau measurements of the pion form factor |F_pi|^2 (s)
Stephane Ghozzi, Fred Jegerlehner
We study possible so far unaccounted isospin breaking effects in the relation between the pion form factor as determined in e^+e^- experiments and the corresponding quantity obtain…
Hadronic vacuum polarization effects in alpha_{em}(M_Z)
F. Jegerlehner
Recent evaluations of the hadronic vacuum polarization contributions to the effective fine-structure constant alpha_{em}(M_Z) are summarized and commented. A new update based on co…
ee4fgamma, A program for e+e- -> 4f, 4fgamma with nonzero fermion masses
Karol Kolodziej, Fred Jegerlehner
A computer program ee4fgamma for calculating cross sections of any four fermion final state of e+e--annihilation at high energy and the corresponding bremsstrahlung reaction that i…
A Model-Independent Treatment of FSR in Low Energy sigma_had Measurements
A. Hoefer, J. Gluza, S. Jadach +1
This paper has been withdrawn by the authors. The parameterization of the FSR tensor has been not the most general.
