Neutron 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...
متن کاملBFKL at next-to-leading order
This is a summary of the contributions on the next-to-leading order corrections to the BFKL equation which were presented to the ‘Small-x and Diffraction’ working group at the 1998 Durham Workshop on HERA Physics. The original BFKL equation [1] allowed the computation of elastic scattering amplitudes in the Regge limit to leading logarithmic (LO) accuracy, i.e. all terms ∼ (αs ln s)n are summed...
متن کاملDecays on Finite Volumes and at Next-to-Leading Order in the Chiral Expansion
We present the ingredients necessary for the determination of physical K → ππ decay amplitudes for ∆I = 3/2 transitions, from lattice simulations at unphysical kinematics and the use of chiral perturbation theory at next-to-leading order. In particular we derive the expressions for the matrix elements I=2〈 ππ|OW |K〉, where OW is one of the operators appearing in the ∆S = 1 weak Hamiltonian, in ...
