The three-pion K-matrix at NLO in ChPT

Journal of High Energy Physics
The three-particle K-matrix, K $$ \mathcal{K} $$ df,3, is a scheme-dependent quantity that parametrizes short-range three-particle interactions in the relativistic-field-theory three-particle finite-volume formalism.

Light hadron spectroscopy at BESIII [PDF]

Proceedings of XVII International Conference on Hadron Spectroscopy and Structure — PoS(Hadron2017), 2015
With data of 1.3 billion J/ψ events and 106 million ψ(2S) events collected with the BESIII detector operating at the BEPCII, many different analyses were performed. New baryon states were observed in partial wave analyses of charmonium decays. A comparison between the branching fraction of B(J/ψ → γfo(1710)) to the recent lattice QCD prediction of J/ψ ...

The distribution amplitude of the η c -meson at leading twist from lattice QCD

Journal of High Energy Physics
Distribution amplitudes are functions of non-perturbative matrix elements describing the hadronization of quarks and gluons. Thanks to factorization theorems, they can be used to compute the scattering amplitude of high-energy processes.

Resummation for lattice QCD calculation of generalized parton distributions at nonzero skewness

Journal of High Energy Physics
Large-momentum effective theory (LaMET) provides an approach to directly calculate the x-dependence of generalized parton distributions (GPDs) on a Euclidean lattice through power expansion and a perturbative matching.

Low-energy interactions between doubly charmed baryons and Goldstone bosons from lattice QCD

Journal of High Energy Physics
We perform a lattice QCD calculation of the S-wave interactions between the ground-state spin-1/2 doubly charmed baryons and Goldstone bosons. The lattice QCD simulations are carried out on four 2 + 1 flavor Wilson-Clover ensembles generated by the CLQCD

Generalized boost transformations in finite volumes and application to Hamiltonian methods

Journal of High Energy Physics
The investigation of hadron interactions within lattice QCD has been facilitated by the well-known quantisation condition, linking scattering phase shifts to finite-volume energies.

Investigation of the low-energy kaons hadronic interactions in light nuclei by AMADEUS

EPJ Web of Conferences, 2016
The AMADEUS experiment deals with the investigation of the low-energy kaon-nuclei hadronic interaction at the DAΦNE collider at LNF-INFN. This study is fundamental to solve longstanding questions concerning interactions of strange quarks in the non ...

Hadron Spectroscopy with Gams

, 1989
Strong interactions at high energy are characterized by the production of a large number of secondary particles. For example, about ten secondaries are produced in π−p collisions at 300 GeV. Of these, four are neutral on the average. Resonances, which are rather readily produced at these energies, also have a tendency to decay through many-body ...

New hadron spectroscopies

International Journal of Modern Physics: Conference Series, 2014
QCD-motivated models for hadrons predict an assortment of "exotic" hadrons that have structures that are more complex than the quark-antiquark mesons and three-quark baryons of the original quark-parton model. These include pentaquark baryons, the six-quark H-dibaryon, and tetraquark and glueball mesons.
