Resummation of QED radiative corrections in a strong constant crossed field

By considering radiative corrections of up to 3rd-loop order, Ritus and Narozhny conjectured that the proper expansion parameter for QED in a strong constant crossed field is g = αχ2/3, where the dynamical quantum parameter χ = e√−(Fp)2/m3 combines the particle momentum p with the external field str...
