Constraints on charm-anticharm asymmetry in the nucleon from lattice QCD

Constraints on charm-anticharm asymmetry in the nucleon from lattice QCD

We present the first lattice QCD calculation of the charm quark contribution to the nucleon electromagnetic form factors GE,Mc(Q2) in the momentum transfer range 0≤Q2≤1.4 GeV2. The quark mass dependence, finite lattice spacing and volume corrections are taken into account simultaneously based on the...
