Working Group on Radiative Corrections and Generators for Low Energy Hadronic Cross Section and Luminosity

25 Jun 2007, 14:30 → 26 Jun 2007, 13:00 Europe/Rome

Aula Seminari (Laboratori Nazionali di Frascati)

The aim of this second meeting is to discuss the current status of
radiative corrections and Monte Carlo generators at low energies.
These radiative corrections and MC generators are crucial for the
measurement of the R-ratio (both with ISR and energy scan),
as well as the determination of luminosity.
