UKQCD Collaboration: C. McNeile, C. Michael
TL;DR
This paper investigates the quark content and decay constants of the eta and eta' mesons using first-principles lattice QCD calculations.
Contribution
It provides a detailed lattice QCD analysis of the flavor singlet pseudoscalar mesons eta and eta' for the first time.
Findings
Determined the quark content of eta and eta' mesons.
Calculated decay constants of eta and eta' mesons.
Enhanced understanding of flavor singlet pseudoscalar mesons in QCD.
Abstract
We study the flavour singlet pseudoscalar mesons from first principles using lattice QCD. We explore the quark content of the and mesons and we discuss their decay constants.
