Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

In this review, we present the current state of the art of our understanding of the spectrum of
excited strongly interacting particles and discuss methods that allow for a systematic and …

The last two decades have witnessed the discovery of a myriad of new and unexpected
hadrons. The future holds more surprises for us, thanks to new-generation experiments …

A bstract We generalize the relativistic field-theoretic three-particle finite-volume scattering
formalism to describe generic DDπ systems in the charm C= 2 sector. This includes the …

Elastic nucleon-pion scattering amplitudes are computed using lattice QCD on a single
ensemble of gauge field configurations with N f= 2+ 1 dynamical quark flavors and m π= 200 …

A bstract We generalize the relativistic field-theoretic (RFT) three-particle finite-volume
formalism to systems of three identical, massive, spin-1/2 fermions, such as three neutrons …

A bstract We study the properties of three-body resonances using a lattice complex scalar φ
4 theory with two scalars, with parameters chosen such that one heavy particle can decay …

A bstract A manifestly relativistic-invariant Lellouch-Lüscher formalism for the decays into
three identical particles with no two-to-three transitions is proposed. Similarly to [1], the …

Two methodologies have been presented in the literature which connect relativistic three-
particle scattering amplitudes with lattice QCD spectra—the “relativistic effective field theory” …

A bstract Recently, the formalism needed to relate the finite-volume spectrum of systems of
nondegenerate spinless particles has been derived. In this work we discuss a range of …
