Аннотация:First results of the CMS experiment from PbPb collisions at nucleon-nucleon center of mass en-
ergy 2.76 TeV are presented. Thanks to its very large acceptance, fine granularity electromagnetic
and hadronic calorimetry, superior muon and tracking systems, and powerful data acquisition and
trigger systems, CMS is an excellent device for the study of hard probes of quark-gluon matter as
well as global event properties in heavy-ion collisions at the LHC.
