Radiative Corrections to Bremsstrahlung in Radiative Return
Scott A. Yost, S. Jadach, B. F. L. Ward
Radiating a photon from the initial state provides a useful tool for studying a range of low energy physics using a high-energy e+ e- accelerator. Accurate results require careful…
Final State of Hawking Radiation in Quantum General Relativity
B. F. L. Ward
We use a new approach to the UV behavior of quantum general relativity, together with some recent results from the phenomenological asymptotic safety analysis of the theory, to dis…
Coherent Exclusive Exponentiation of 2f Processes in e+e- Annihilation
Z. Was, S. Jadach, B. F. L. Ward
In the talk we present the Coherent Exclusive Exponentiation (CEEX) which is implemented in the KK MC event generator for the process e+e- to f bar f +n gamma, f=mu,tau,d,u,s,c,b f…
Two-Fermion Production in Electron-Positron Collisions
Michael Kobel, Zbigniew Was, C. Ainsley +31
This report summarizes the results of the two-fermion working group of the LEP2-MC workshop, held at CERN from 1999 to 2000. Recent developments in the theoretical calculations of…
Four-Fermion Production in Electron-Positron Collisions
Martin W. Gruenewald, Giampiero Passarino, E. Accomando +37
This report summarises the results of the four-fermion working group of the LEP2-MC workshop, held at CERN from 1999 to 2000. Recent developments in the calculation of four-fermion…
Precision Calculation of Bhabha Scattering at LEP
W. Placzek, S. Jadach, M. Melles +2
For the small-angle Bhabha-scattering process, we consider the error budget for the calculation of the LEP/SLC luminosity in the Monte Carlo event generator BHLUMI 4.04, from the s…
