چکیده

We investigate the electromagnetic mass splittings in the pseudoscalar meson and nucleon systems by combining 2+1 flavor domain wall fermion gauge configurations, generated by the RBC and UKQCD collaborations, and quenched, non-compact, lattice QED configurations. We analyze finite volume effects by using 16 3 × 32 and 24 3 × 64 lattices. Isospin symmetry breaking effects in the pion and nucleon masses Ran Zhou

We calculate at two-loop order in chiral perturbation theory the electromagnetic corrections to the dominant two-pion exchange nucleon-nucleon interaction that is generated by the isoscalar πN contact-vertex proportional to the large low-energy constant c 3. We find that the respective 2πγ-exchange potential contains sizeable isospin-breaking components which amount to about −1% of the strongly...

Isospin Violation in the Two–nucleon System

I discuss isospin violation in an effective field theory appraoch of the nucleon– nucleon interaction. The observed leading order charge independence breaking is explained in terms of one–pion exchange together with a four–nucleon contact term. A general classification scheme of corrections to this leading order results is presented and an explanation is offered why charge–dependent pion–nucleo...

Isospin Splitting in the Pion-Nucleon Couplings from QCD Sum Rules

We use QCD sum rules for the three point function of a pseudoscalar and two nucleonic currents in order to estimate the charge dependence of the pion nucleon coupling constant gNNπ coming from isospin violation in the strong interaction. The effect can be attributed primarily to the difference of the quark condensates < ūu > and < d̄d >. Assuming that the π is a pure isostate we obtain for the s...

Dominant 2πγ-exchange nucleon-nucleon interaction: Spin-spin and tensor potentials

We calculate at two-loop order in chiral perturbation theory the electromagnetic corrections to the two-pion exchange nucleon-nucleon interaction that is generated by the isovector spin-flip ππNN contact-vertex proportional to the large low-energy constant c4 ≃ 3.4GeV−1. We find that the respective 2πγ-exchange potentials contain sizeable isospinbreaking components which reach up to −4% of corr...

Isospin Breaking in the Nucleon Isovector Axial Charge from QCD Sum Rules

The isospin breaking in the nucleon isovector axial charge, g3 A, are calculated within the external field QCD sum-rule approach. The isospin violations arising from the difference in up and down current quark masses and in up and down quark condensates are included; electromagnetic effects are not considered. We find δg3 A/g 3 A ≈ (0.5− 1.0)× 10 −2, where δg3 A = (g 3 A)p + (g 3 A)n and g3 A =...
