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

19 apr 2010, 14:30 → 20 apr 2010, 14:30 Europe/Rome

Aula Seminari (Laboratori Nazionali di Frascati<!-- ID_UTENTE=506 -->)

The aim of this seventh meeting is to discuss the Working Group Report on 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.
