We focus on wave functions in the Landau and Coulomb gauges. We observe the formation of a scalar u-d diquark pair within the proton in Landau gauge, which is not present in Coulomb gauge. The overall distortion of the wave functions under a very large magnetic field, as demanded by the quantisation conditions on the field, is quite small.en© Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.Conference paper00201089202-s2.0-8505535056129609Kamleh, W.
