Baryon-Baryon Interactions from the Lattice
I discuss the latest progress in calculating baryon-baryon interactions with lattice QCD. The latest results from the NPLQCD collaboration for nucleon-nucleon scattering along with preliminary calculations of hyperon-nucleon scattering are presented.

متن کاملBaryon Spectroscopy on the Lattice
Quantum Chromodynamics (QCD) provides an excellent description of nature; however, the theory suffers from divergences that must be removed to render it finite. Lattice QCD provides an apriori non-perturbative regularization of QCD that makes it amenable to analytic and computational methods. No model assumptions other than QCD itself are needed to formulate the theory. This review surveys the ...
متن کاملBaryon spectroscopy on the lattice: recent results
Progress in determining the baryon spectrum using computer simulations of quarks and gluons in lattice QCD are summarized and some future plans are outlined. Baryon spectroscopy is plagued by numerous unresolved issues. The quark model predicts many more states[1, 2] than are currently known. Experiments in Hall B at Jefferson Laboratory are currently mapping out of the spectrum of N nucleon ex...
متن کاملBaryon Spectroscopy in Lattice QCD
We review recent developments in the study of excited baryon spectroscopy in lattice QCD. After introducing the basic methods used to extract masses from correlation functions, we discuss various interpolating fields and lattice actions commonly used in the literature. We present a survey of results of recent calculations of excited baryons in quenched QCD, and outline possible future direction...
متن کاملBaryon Spectroscopy from Lattice QCD
Experiments show that many excited-state hadrons exist, and there are significant experimental efforts to map out the QCD resonance spectrum, such as Hall B and the proposed Hall D at Jefferson Lab, ELSA associated with the University of Bonn, COMPASS at CERN, PANDA at GSI, and BESIII in Beijing. Hence, there is a great need for ab initio determinations of such states in lattice QCD. To extract...
