Nucleon axial and pseudoscalar form factors from lattice QCD at the physical point

نویسندگان

چکیده

We compute the nucleon axial and induced pseudoscalar form factors using three ensembles of gauge configurations, generated with dynamical light quarks mass tuned to approximately their physical value. One also includes strange charm close physical. The latter ensemble has large statistics finer lattice spacing it is used obtain final results, while other two are for assessing volume effects. factor computed these ensembles. examine momentum dependence as well relations based on pion pole dominance partially conserved axial-vector current hypothesis.

Nucleon axial form factor from lattice QCD.

Results for the isovector axial form factors of the proton from a lattice QCD calculation are presented for both point-split and local currents. They are obtained on a quenched 163 × 24 lattice at β = 6.0 with Wilson fermions for a range of quark masses from strange to charm. For each quark mass, we find that the axial form factor falls off slower than the corresponding proton electric form fac...

Nucleon electromagnetic form factors from lattice QCD

It is imperative that lattice QCD serve to develop our understanding of hadron structure and, where possible, to guide the interpretation of experimental data. There is now a great deal of effort directed at the calculation of the electroweak form factors of the nucleon, where for example, measurements at Jefferson Laboratory have recently revealed surprising behaviour in the ratio GE/GM. While...

Nucleon and Pion-nucleon Form Factors from Lattice Qcd

The isovector Nucleon electromagnetic form factors GE(q ) and GM(q ) are evaluated in Lattice QCD using Wilson fermions. A lattice of spatial extent 3 fm is used in the quenched theory allowing the extraction of the form factors for momentum transfer squared between 0.1 and 2 GeV for lowest pion mass of about 400 MeV. The calculation is also performed using two degenerate dynamical flavors of W...

pi NN and pseudoscalar form factors from lattice QCD.

The πNN form factor gπNN (q ) is obtained from a quenched lattice QCD calculation of the pseudoscalar form factor gP (q ) of the proton with pion pole dominance. We find that gπNN (q ) fitted with the monopole form agrees well with the Goldberger-Treiman relation and is much preferred over the dipole form. The monopole mass is determined to be 0.75 ± 0.14GeV which shows that gπNN (q ) is rather...
