Hadrons are systems bound by the strong interaction, which is described at the fundamental level by Quantum Chromodynamics (QCD). While QCD is well understood at high energy in the perturbative regime, low-energy phenomena such as the binding of quarks and gluons within hadrons are more difficult to predict. High precision measurements are most useful to test the reliability of several models and techniques, such as constituent-quark models or lattice-QCD calculations, into predicting the mass spectrum and the properties of the hadrons.
The 7 and 8 TeV proton-proton collision data collected by the LHCb experiment during 2011 and 2012 provide a rich sample of heavy flavour production and decays in which the studies of hadron properties can be performed. A summary of the recent experimental results from LHCb including studies of excited D and B mesons will be presented.
