Title: Nucleon electromagnetic form factors from lattice QCD using a nearly physical pion mass

Abstract

We propose lattice QCD calculations of nucleon electromagnetic form factors using pion masses m_π = 149, 202, and 254 MeV and an action with clover-improved Wilson quarks coupled to smeared gauge fields, as used by the Budapest-Marseille-Wuppertal Collaboration. Particular attention is paid to the removal of the effects of excited-state contamination by calculations at three source-sink separations and the use of the summation and generalized pencil-of-function methods. The combination of a calculation at the nearly physical mass m_π = 149 MeV in a large spatial volume (m_πL_s = 4.2) and the removal of excited-state effects yields agreement with experiment for the electric and magnetic form factors G_E(Q²) and G_M(Q²) up to Q² = 0.5 GeV².

Computing the nucleon charge and axial radii directly at $Q^{2} = 0$ in lattice QCD

Journal Article Hasan, Nesreen ; Green, Jeremy ; Meinel, Stefan ; ... - Physical Review D

We describe a procedure for extracting momentum derivatives of nucleon matrix elements on the lattice directly at Q² = 0 . This is based on the Rome method for computing momentum derivatives of quark propagators. We apply this procedure to extract the nucleon isovector magnetic moment and charge radius as well as the isovector induced pseudoscalar form factor at Q² = 0 and the axial radius. For comparison, we also determine these quantities with the traditional approach of computing the corresponding form factors, i.e. Gmore »« less

Roper state from overlap fermions

Journal Article Sun, Mingyang ; Chen, Ying ; Wang, Gen ; ... - Physical Review D

The Roper state is extracted with valence overlap fermions on a 2 + 1-flavor domain-wall fermion lattice (spacing a = 0.114 fm and m π = 330 MeV) using both the sequential empirical Bayes (SEB) method and the variational method. The results are consistent, provided that a large smearing-size interpolation operator is included in the variational calculation to have better overlap with the lowest radial excitation. The SEB and variational calculation with large smearing size are also carried out for an anisotropic clover lattice with similar parameters (spatial lattice spacing a s = 0.12 fm and pion mass m_π =more »« less

Controlling excited-state contamination in nucleon matrix elements

Journal Article Yoon, Boram ; Gupta, Rajan ; Bhattacharya, Tanmoy ; ... - Physical Review D

We present a detailed analysis of methods to reduce statistical errors and excited-state contamination in the calculation of matrix elements of quark bilinear operators in nucleon states. All the calculations were done on a 2+1-flavor ensemble with lattices of size 32³ × 64 generated using the rational hybrid Monte Carlo algorithm at a = 0.081 fm and with M_π = 312 MeV. The statistical precision of the data is improved using the all-mode-averaging method. We compare two methods for reducing excited-state contamination: a variational analysis and a 2-state fit to data at multiple values of the source-sink separation t_sep. Wemore »« less

High-precision calculation of the strange nucleon electromagnetic form factors

Journal Article Green, Jeremy ; Meinel, Stefan ; Engelhardt, Michael G. ; ... - Physical Review. D, Particles, Fields, Gravitation and Cosmology

We report a direct lattice QCD calculation of the strange nucleon electromagnetic form factors G^s_E and G^s_M in the kinematic range 0 ≤ Q² ≤ 1.2GeV². For the first time, both G^s_E and G^s_M are shown to be nonzero with high significance. This work uses closer-to-physical lattice parameters than previous calculations, and achieves an unprecented statistical precision by implementing a recently proposed variance reduction technique called hierarchical probing. We perform model-independent fits of the form factor shapes using the z-expansion and determine the strange electric and magnetic radii and magnetic moment. As a result, we compare our results to parity-violatingmore »« less
