Beyond the quark model of hadrons from lattice QCD
C. Michael
TL;DR
This paper uses lattice QCD to analyze meson spectra, including flavor singlet and non-singlet differences, scalar mesons with glueball effects, and hybrid mesons, providing insights into their structure and decays.
Contribution
It offers a detailed lattice QCD study of meson mass splittings, glueball influences, and hybrid meson properties, advancing understanding of non-perturbative QCD effects.
Findings
Quantifies OZI-violating contributions to meson masses
Provides spectrum and decay analysis for scalar and hybrid mesons
Highlights the role of glueballs in meson structure
Abstract
Lattice QCD can give direct information on OZI-violating contributions to mesons. Here we explore the contributions that split flavour singlet and non-singlet meson masses. I discuss in detail the spectrum and decays for scalar mesons (ie including glueball effects). I also review the status of hybrid mesons and their decays.
