Lepton Magnetic Moments: What They Tell Us
Fred Jegerlehner
Recently, the exciting new Fermilab (FNAL) Muon g-2 measurement impressively confirmed the final Brookhaven (BNL) result from 2004, and with a result four times more precise, has l…
The Decays within BHLS and the Muon HVP
Maurice Benayoun, Luigi DelBuono, Fred Jegerlehner
The departure of the latest FNAL experimental average for the muon anomalous magnetic moment measurements having increased from to , with respect to…
The Muon g-2 in Progress
Fred Jegerlehner
Two next generation muon experiments at Fermilab in the US and at J-PARC in Japan have been designed to reach a four times better precision from 0.54 ppm to 0.14 ppm and the…
Muon g-2 estimates : Can one trust Effective Lagrangians and global fits ?
M. Benayoun, P. David, L. DelBuono +1
Previous studies have shown that the Hidden Local Symmetry (HLS) Model, supplied with appropriate symmetry breaking mechanisms, provides an Effective Lagrangian (BHLS) which encomp…
Constraining the Hadronic Contributions to the Muon Anomalous Magnetic Moment
H. Czyż, A. Denig, S. Eidelman +19
The mini-proceedings of the Workshop on "Constraining the hadronic contributions to the muon anomalous magnetic moment" which included the "13th meeting of the Radio MonteCarLow WG…
Quest for precision in hadronic cross sections at low energy: Monte Carlo tools vs. experimental data
S. Actis, A. Arbuzov, G. Balossini +53
We present the achievements of the last years of the experimental and theoretical groups working on hadronic cross section measurements at the low energy e+e- colliders in Beijing,…
Essentials of the Muon g-2
F. Jegerlehner
The muon anomalous magnetic moment is one of the most precisely measured quantities in particle physics. Recent high precision measurements (0.54ppm) at Brookhaven reveal a ``discr…
Measuring the FSR--inclusive pi+pi- cross section
J. Gluza, A. Hoefer, S. Jadach +1
Final state radiation (FSR) in pion--pair production cannot be calculated reliably because of the composite structure of the pions. However, FSR corrections have to be taken into a…
Results for all reactions e+ e- -> 4f, 4f + gamma with nonzero fermion masses
F. Jegerlehner, K. Kolodziej
We accomplish our efforts to obtain predictions for all four-fermion final states of e+ e- annihilation and the corresponding bremsstrahlung reactions which are possible in the fra…
Pion Pair Production with Higher Order Radiative Corrections in Low Energy e+e- Collisions
A. Hoefer, J. Gluza, F. Jegerlehner
The complete one-loop QED initial state, final state and initial--final state interference corrections to the process e+e- -> pi+pi- are presented. Analytic formulae are given for…
Hadronic Contributions to the Photon Vacuum Polarization and their Role in Precision Physics
F. Jegerlehner
I review recent evaluations of the hadronic contribution to the shift in the fine structure constant and to the anomalous magnetic moment of the muon. Substantial progress in a pre…
Fermion mass effects in e+e- --> 4f and e+e- --> 4f gamma with cuts
F. Jegerlehner, K. Kolodziej
The fermion mass effects in e+ e- --> 4f and in the corresponding bremsstrahlung reactions in the presence of realistic cuts are studied. It is shown that, for some four--fermion f…
Confronting electroweak precision measurements with New Physics models
M. Czakon, J. Gluza, F. Jegerlehner +1
Precision experiments, such as those performed at LEP and SLC, offer us an excellent opportunity to constrain extended gauge model parameters. To this end, it is often assumed, tha…
Physics with e^+e^- Linear Colliders
E. Accomando
We describe the physics potential of linear colliders in this report. These machines are planned to operate in the first phase at a center-of --mass energy of 500 GeV, bef…

S. Jadach, O. Nicrosini, H. Anlauf +21
The results obtained by the "Event Generators for Bhabha Scattering" working group during the CERN Workshop "Physics at LEP2" (1994/1995) are presented.
