Beyond Standard Model at LHC

摘要

LHC will be able to investigate several theoretical models that pre-dict exotic objects. This report is focused on the evidence of high-mass resonancesdecading into two muons and of new heavy long-lived charged particles behavingin collider experiments as stable particles. Both cases are discussed from an ex-perimetal point of view, taking as example the CMS experiment, and the evidenceat LHC after 100 pb~(-1)of integrated luminosity is reported.
