A next - to - next - to - leading - order pp → ppπ 0 Transition Operator in Chiral Perturbation Theory

We present a systematic analysis of next-to-next-to-leading-order diagrams that contribute to the pp → ppπ 0 production at threshold. Analytic expressions are given for the effective transition operators, and the relative importance of various types of diagrams is discussed. The vertex-correction-type graphs are found to give only small corrections to lower order graphs in conformity with expec...

Subtractive renormalization of chiral effective theory NN potentials up to next-to-next-to-leading order

We have developed a subtractive renormalization method with which we can evaluate nucleonnucleon (NN) scattering phase shifts produced by the NN potential obtained at leading, nextto-leading, and next-to-next-to-leading order (NNLO) in chiral effective theory (χET). In this method the low-energy constants associated with short-distance NN physics are eliminated from the Lippmann-Schwinger equat...

Baryon Chiral Perturbation Theory to One Loop

Pion Double Charge exchange (DCX) scattering off a nuclear target at threshold, is calculated within the framework of Heavy Baryon Chiral Perturbation Theory (HBChPT) to one loop. An estimate for the (2-nucleon) 1-loop correction is obtained in the static limit and using an impulse approximation. We find a small (1.6%) increase relative to the leading order tree graphs. PACS numbers: 12.39.Fe, ...

Baryon chiral perturbation theory

We provide an introduction to the power-counting issue in baryon chiral perturbation theory and discuss some recent developments in the manifestly Lorentz-invariant formulation of the one-nucleon sector. As explicit applications we consider the chiral expansion of the nucleon mass, its convergence properties, and calculations of the electromagnetic and axial form factors of the nucleon.

Partially quenched chiral perturbation theory in the epsilon regime at next-to-leading order

We calculate the partition function of partially quenched chiral perturbation theory in the epsilon regime at next-to-leading order using the supersymmetry formulation developed by Sharpe and Shoresh. We include a nonzero imaginary chemical potential and show that the finite-volume corrections to the low-energy constants Σ and F for the partially quenched partition function, and hence for spect...
