Maximum entropy analysis of the spectral functions in lattice QCD

M Asakawa, Y Nakahara, T Hatsuda - Progress in Particle and Nuclear …, 2001 - Elsevier
First principle calculation of the QCD spectral functions (SPFs) based on the lattice QCD
simulations is reviewed. Special emphasis is placed on the Bayesian inference theory and …

Hadronic spectral functions in lattice QCD

Y Nakahara, M Asakawa, T Hatsuda - Physical Review D, 1999 - APS
QCD spectral functions of hadrons in the pseudoscalar and vector channels are extracted

Exotic hybrid mesons with light quarks

C Bernard, T Blum, TA DeGrand, C DeTar… - Nuclear Physics B …, 1997 - Elsevier
Hybrid mesons, made from a quark, an antiquark and gluons, can have quantum numbers
inaccessible to conventional quark-antiquark states. Confirmation of such states would give …

Spectral change of hadrons and chiral symmetry

T Hatsuda - AIP Conference Proceedings, 2001 - pubs.aip.org
After a brief summary of the QCD phase structure with light quarks, we discuss two recent
developments on in-medium hadrons. First topic is the σ-meson which is a fluctuation of the …

Bayesian analysis of many-pole fits of hadron propagators in lattice QCD

D Makovoz - Nuclear Physics B-Proceedings Supplements, 1997 - Elsevier
We use Bayes' probability theorem to analyze many-pole fits of hadron propagators. An
alternative method of estimating values and uncertainties of the fit parameters is offered …
