HOW TO CALCULATETHE ELASTICSCATFERINGMATRiX IN TWO-DIMENSIONALQUANTUMFIELD THEORIES BY NUMERICAL SIMULATION
Martin Lüscher,Ulli Wolff +1 more
TL;DR: In this paper, a method to calculate the elastic scattering amplitude at low energies in two-dimensional quantum field theories is proposed and tested in a numerical simulation of the 0(3) non-linear if-model on a simple square lattice.
Journal ArticleDOI
Exotics: Heavy pentaquarks and tetraquarks
TL;DR: In the last decade, there has been an explosion of data from both e+e− and hadron colliders, and many recently observed states that do not fit into this picture are called generically "exotics" as discussed by the authors.

TL;DR: A review of the progress in the field of exotic $XYZ$ hadrons can be found in this article, with a summary on future prospects and challenges, as well as a survey of the current state-of-the-art.

Scattering processes and resonances from lattice QCD
TL;DR: In this paper, the authors review progress in the study of few-hadron reactions in which resonances and bound states appear using lattice QCD techniques and present a leading approach that takes advantage of the periodic finite spatial volume used in lattice-QCD calculations to extract scattering amplitudes from the discrete spectrum of QCD eigenstates in a box.

Exotics: Heavy Pentaquarks and Tetraquarks
TL;DR: In the last decade, there has been an explosion of data from both $e^+e^-$ and hadron colliders and there are many recently observed states that do not fit into this picture as mentioned in this paper.

Nucleon-Nucleon Potential and its Non-locality in Lattice QCD
TL;DR: In this paper, a quenched lattice QCD simulation for two nucleons with finite scattering energy was performed on a hypercubic lattice with the lattice spacing a ~ 0.137 fm and the spatial extent L_s ~ 4.4 fm.

Gupta-Bleuler formalism with scalar fermions in massless Yang-Mills theory
E. Rudolph,Hans-Peter Dürr +1 more
TL;DR: In this paper, it is shown that the tree diagrams of the S-matrix are gauge invariant and that the Smatrix leads out of the physical subspace to a positive semi-definite metric.

Lattice study of nuclear forces
Noriyoshi Ishii,for Pacs-Cs +1 more
TL;DR: In this paper, the authors extended the Luescher finite volume method to generate the potentials from Bethe-Salpeter (BS) wave functions, which can reproduce BS wave functions in which the information of phase shift is embeded in the long distance part.

Lambda-Nucleon and Nucleon–Nucleon Interactions on the Lattice
TL;DR: A lattice QCD method to calculate realistic nuclear potentials is developed in this paper, which is one of the possible extensions of Luscher's finite volume method for scattering phase shifts.
