The main goal of this workshop is to bring experimentalists and theorists together to reflect on the current and future opportunities in the field of particle physics. Subjects to be discussed include Higgs, QCD, flavor and BSM physics at the LHC and HL-LHC. The target participants are researchers in Brazil, Argentina and other south american countries directly involved in this field, to stimulate close and profitable collaborations for the next decade. This would be the first workshop of this kind in the region, and we hope that indeed it could develop into a Workshop with a regular frequency
