Compton scattering from the proton in an effective field theory with explicit Delta degrees of freedom
Judith A. McGovern, Daniel R. Phillips, Harald W. Grießhammer
We analyse the proton Compton-scattering differential cross section for photon energies up to 325 MeV using Chiral Effective Field Theory and extract new values for the electric an…
Pion-less Effective Field Theory on Low-Energy Deuteron Electro-Disintegration
Stefan Christlmeier, Harald W. Griesshammer
In view of its relation to Big-Bang Nucleo-Synthesis and a reported discrepancy between nuclear models and data taken at S-DALINAC, electro-induced deuteron break-up 2H(e,e' p)n is…
Estimating Consequences of 3-Body Forces
Harald W. Griesshammer
Classifying the strengthes of three-body forces 3BFs with the condition that observables must be cut-off independent, i.e. renormalised at each order, leads to surprising results w…
Neutron Polarisabilities from Deuteron Compton Scattering in \chiEFT
Harald W. Griesshammer
Chiral Effective Field Theory is for photon energies up to 200 MeV the tool to accurately determine the polarisabilities of the neutron from deuteron Compton scattering. A multipol…
Effective field theory calculation of nd radiative capture at thermal energies
H. Sadeghi, S. Bayegan, Harald W. Griesshammer
The cross section for the thermal neutron capture by the deuteron is calculated with pionless Effective Field Theory(EFT). No new Three-Nucleon forces are needed up to next-to-next…
How To Classify 3-Body Forces -- And Why
Harald W. Griesshammer
For systems with only short-range forces and shallow 2-body bound states, the typical strength of any 3-body force in all partial-waves, including external currents, is systematica…
