Scattering From Effective Field Theory
We examine the role of the ∆∆ intermediate state in NN scattering in the S0 channel. The computation is performed at lowest order in an effective field theory involving local four-fermion operators and one pion exchange using dimensional regularization with MS. As first discussed by Weinberg, in the theory with only nucleons the large scattering length in this channel requires a small scale for...
متن کاملD-brane effective field theory from string field theory
Open string field theory is considered as a tool for deriving the effective action for the massless or tachyonic fields living on D-branes. Some simple calculations are performed in open bosonic string field theory which validate this approach. The level truncation method is used to calculate successive approximations to the quartic terms φ4, (AAμ) 2 and [Aμ, Aν ] 2 for the zero momentum tachyo...
متن کاملNucleon-Nucleon interactions from effective field theory
We have established a new convergent scheme to treat analytically nucleon-nucleon interactions from a chiral effective field theory. The Kaplan-Savage-Wise (KSW) amplitudes are resummed to fulfill the unitarity or right hand cut to all orders below pion production threshold. This is achieved by matching order by order in the KSW power counting the general expression of a partial wave with resum...
متن کاملTwo-nucleon systems from effective field theory
We elaborate on a new technique for computing properties of nucleon-nucleon interactions in terms of an effective field theory derived from low energy NN scattering data. Details of how the expansion is carried out to higher orders are presented. Analytic formulae are given for the amplitude to subleading order in both the S0 and S1 − D1 channels.
متن کاملNucleon-Nucleon Scattering from Effective Field Theory
We perform a nonperturbative calculation of the S0 NN scattering amplitude, using an effective field theory (EFT) expansion. We use dimensional regularization throughout, and the MS renormalization scheme; our final result depends only on physical observables. We show that the EFT expansion of the quantity |p| cot δ(p) converges at momenta much greater than the scale Λ that characterizes the de...
