Spectroscopy of hadrons containing heavy quarks is an important part of the LHC physics program. Precise measurements of observables like hadron masses are crucial to test the validity of QCD models, and at the same time they give the opportunity to search for new particles and previously unobserved decay modes. A large amount of results in hadronic spectroscopy has been already produced by ATLAS, CMS and LHCb experiments with data collected at √ s = 7 TeV. This review summarizes the most relevant measurements of heavy hadrons masses, many of which are already more precise than the previous world best values. Particular emphasis is given to the first observations of new particles, and to the interpretation of some controversial exotic states.

Abstract
Spectroscopy of hadrons containing heavy quarks is an important part of the LHC physics program. Precise measurements of observables like hadron masses are crucial to test the validity of QCD models, and at the same time they give the opportunity to search for new particles and previously unobserved decay modes. A large amount of results in hadronic spectroscopy has been already produced by ATLAS, CMS and LHCb experiments with data collected at √ s = 7 TeV. This review summarizes the most relevant measurements of heavy hadrons masses, many of which are already more precise than the previous world best values. Particular emphasis is given to the first observations of new particles, and to the interpretation of some controversial exotic states.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
