The Eta-prime Meson with Staggered Fermions

  title={The Eta-prime Meson with Staggered Fermions},
  author={Lakshmi Venkataraman and Gregory W. Kilcup},
  journal={arXiv: High Energy Physics - Lattice},
We have computed the eta-prime pseudoscalar octet mass splitting using staggered fermions on both dynamical and quenched gauge configurations. We have used Wuppertal smeared operators to reduce excited state contributions. We compare our results with the theoretical forms predicted by partially quenched chiral perturbation theory in the lowest order. Using lattice volumes of size 16^3 x 32 with a^{-1}=2GeV we obtain results consistent with the physical eta-prime mass. We also demonstrate that… 

A High Statistics Study of Flavour-Singlet Mesons with Staggered Fermions

We present some early results from a high statistics study of the scalar and pseudoscalar singlet sectors of lattice QCD using 2+1 flavours of Asqtad improved staggered fermions. The use of the

Pseudoscalar transition form factors and the hadronic light-by-light contribution to the muon g-2

We present preliminary results from our calculation of the pseudoscalar transition form factors of the η and η′ mesons using staggered quarks on N f = 2 + 1 + 1 gauge ensembles generated by the

'Pseudoscalar flavor-singlets and staggered fermions '

The Asqtad improved staggered fermion formalism has been a valuable tool in successfully calculating the non-singlet parts of the hadronic spectrum. We are engaged in a project to calculate the

η′ Meson from Two Flavor Dynamical Domain Wall Fermions

We explore the spectrum of a flavor singlet pseudoscalar meson, η′, in two-flavor (Nf = 2) lattice Quantum Chromo Dynamics (QCD). The continuum-like relation between the topology of the QCD vacuum

Nonperturbative QCD Simulations with 2+1 Flavors of Improved Staggered Quarks

Dramatic progress has been made over the last decade in the numerical study of quantum chromodynamics (QCD) through the use of improved formulations of QCD on the lattice (improved actions), the

Lattice QCD with 12 Degenerate Quark Flavors

We report on new data from additional zero temperature simulations of QCD with 12 flavors. This is a continuation of previous studies using the DBW2 gauge action and naive staggered fermions. With

Non–perturbative aspects of physics beyond the Standard Model

The Large Hadron Collider (LHC) and the four major experiments set up along its 27 kilometers of circumference (ATLAS, CMS, ALICE and LHCb), have recently started to explore the high–energy frontier
