This Workshop is part of a series of workshops on physics at Linear Colliders, organized in Italy every year to stimulate and gather together the Italian community interested in Linear Colliders (LCs). The workshop invites scientists from everywhere in the world to discuss together topical arguments related to LCs. Previous editions have taken place in Florence, Perugia and Frascati (twice). This year the main topic chosen is QCD and the venue is the European Center for Theoretical Studies in Nuclear Physics and Related areas (ECT*).
