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...
متن کاملPartially 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...
متن کاملA new global fit of the Li at next-to-next-to-leading order in Chiral Perturbation Theory
A new fit is done to obtain numerical values for the order p4 low-energy-constants Li in Chiral Perturbation Theory. This includes both new data and new calculated observables. We take into account masses, decay constants, Kl4, ππ and πK scattering lengths and slopes and the slope of the pion scalar formfactor. We compare in detail where the changes w.r.t. to the 10 year old “fit 10” come from....
متن کاملNeutron matter at next-to-next-to-next-to-leading order in chiral effective field theory.
Neutron matter presents a unique system for chiral effective field theory because all many-body forces among neutrons are predicted to next-to-next-to-next-to-leading order (N(3)LO). We present the first complete N(3)LO calculation of the neutron matter energy. This includes the subleading three-nucleon forces for the first time and all leading four-nucleon forces. We find relatively large cont...
متن کاملSubtractive 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...
