Chiral corrections to lattice calculations of charge radii.

چکیده
Logarithmic divergences in pion and proton charge radii associated with chiral loops are investigated to assess systematic uncertainties in current lattice determi-nations of charge radii. The chiral corrections ooer a possible solution to the long standing problem of why present lattice calculations yield proton and pion radii which are similar in size.

متن کامل0 Incorporating Chiral Symmetry and Heavy Quark Theory in Extrapolations of Octet Baryon Charge Radii
We extrapolate lattice calculations of electric charge radii of the spin-1/2 baryon octet to the physical regime. The extrapolation procedure incorporates chiral perturbation theory and heavy quark effective theory in the appropriate limits. In particular, this procedure includes the non-analytic, logarithmic terms from pion loops. The electric charge radii of the nucleons and Σ − obtained from...

متن کاملElectromagnetic Properties of the Baryon Decuplet in Quenched and Partially Quenched Chiral Perturbation Theory
Abstract We calculate electromagnetic properties of the decuplet baryons in quenched and partially quenched chiral perturbation theory. We work at next-to-leading order in the chiral expansion, leading order in the heavy baryon expansion, and obtain expressions for the magnetic moments, charge radii, and electric quadrupole moments. The quenched calculation is shown to be pathological since onl...

We compute the octet baryon charge radii to O(1/ΛχMN) in heavy baryon chiral perturbation theory (HBχPT). We examine the effect of including the decuplet of spin-32 baryons explicitly. We find that it does not improve the level of agreement between the HBχPT and experimental values for the Σ− charge radius. The study of electromagnetic (EM) form factors is an important tool used in developing a...
