Proton-proton fusion is considered in the effective field theory of Kaplan, Savage and Wise. Coulomb effects are included systematically in a non-perturbative way. Including the dimension-eight derivative coupling which determines the effective ranges of the scattering amplitudes, next-to-leading order corrections to the fusion rate are calculated. When the renormalization mass is well above th...
متن کاملProton–proton fusion in pionless effective theory
Article history: Received 30 January 2008 Accepted 19 August 2008 Available online 28 August 2008 Editor: W. Haxton PACS: 21.45.Bc 26.20.Cd 26.65.+t The proton–proton fusion reaction, pp → de+ν , is studied in pionless effective field theory (EFT) with di-baryon fields up to next-to leading order. With the aid of the di-baryon fields, the effective range corrections are naturally resummed up to...
متن کاملProton–proton fusion in effective field theory to fifth order
The proton–proton fusion process pp → de+νe is calculated at threshold to fifth order in pionless effective field theory. There are two unknown two-body currents contributing at the second and fourth orders. Combined with the previous results for νed and ν̄ed scattering, computed to third order in the same approach, we conclude that a ∼ 10% measurement of reactor ν̄ed scattering measurement could...
متن کاملOverview of Sample Proton and Deuteron Radiative Corrections Proton Corrections
This document is intended to provide a short overview of the electromagnetic ra-diative corrections procedure for the SAMPLE proton and deuterium experiments. Electroweak corrections are not considered here. There are two basic types of ra-diative processes considered here, external and internal. External processes describe energy loss of the incident electron due bremsstrahlung radiation as th...
متن کاملQuantum mechanical proton range in human body
Introduction: Proton therapy delivers radiation to tumor tissue in a much more confined way than conventional photon therapy thus allowing the radiation oncologist to use a greater dose while still minimizing side. Materials and Methods: protons release most of their energy within the tumor region. As a result, the treating physician can potentially give an...
