Accessing the hadron spectrum from Quantum Chromodynamics (QCD) poses several challenges due to its nonperturbative nature and the fact that many states couple strongly to multi-particle decay channels. Recent advances in theoretical formalisms and numerical algorithms have made it possible to study few-hadron systems directly from QCD. A synergistic approach combining lattice QCD with...

Significant progress in studies of hadron spectroscopy has been accomplished by the LHCb experiment, highlighted by its discovery of 76 new conventional and exotic hadrons. This is thanks to its excellent mass resolution and unique capabilities in hadron identification and triggering on heavy flavor events. Recent LHCb results in conventional and exotic hadron spectroscopy will be reviewed.

Whether an exotic hadron is elementary or composite is a statement about which fields appear in the effective Lagrangian. The Weinberg criterion has been invoked on the X(3872) to argue for a molecular nature, but it is applied to LHCb data fitted with a Flatté amplitude, which contains an elementary X field: the molecular conclusion is drawn from a fit that assumes the opposite --- and the...

We show how the Born--Oppenheimer effective field theory (BOEFT)
Go to contribution page
provides a unified description of ordinary and exotic quarkonia grounded
on the non-relativistic expansions of QCD and supplemented with lattice
QCD inputs. We show applications of the BOEFT to tetraquarks,
pentaquarks, quarkonium hybrids and to assess threshold effects in the
quarkonium spectrum. We present the insights...
