Supported by Generalitat Valenciana, under Grant Prometeo/2009/091 IFIC's AHEP Group at Valencia is hosting an Extended Astroparticle and High Energy Physics Workshop Program in the Fall of 2009.The aim of the program is to discuss critically latest research topics in this field such as: neutrino oscillation parameters and solar physics, reactor and accelerator results, non-standard neutrino interactions, dark matter detection, cosmological leptogenesis, LHC physics,lepton flavor violation, as well as more theoretical issues such as unification, flavor symmetries and extra dimensions. Visitors and speakers include: Prof. G. Altarelli (CERN & Rome), Dr. Federica Bazzocchi (Vrije Universiteit Amsterdam), Prof. Yong-Yeon Keum (Korea Univ.), Dr. Eduardo Peinado (AHEP/IFIC), Dr. David Cerdeno (UAM-IFT), Philip Leser (Wurzburg), Dr. Omar Miranda (Cinvestav Mexico), Dr. Siba Prasad Das (AHEP/IFIC), Dr. Diego Restrepo (U. Antioquia), Dr. Manuel Toharia (University of Maryland), Dr. Marco Taoso (AHEP/IFIC), and others.
