Coulomb corrections to the parameters of the Molière multiple scattering theory

“…The specificity of the expressions presented in this work is that they determine the Coulomb correction to some important parameters of the Molière multiple scattering theory, i.e. the screening angular parameter χ B a and also the parameters b, B, and θ 2 of the Molière expansion method [9].Molière's theory is of interest for numerous applications related to particle transport in matter; is widely used in most of the transport codes; and also presents the most used tool for taking into account the multiple scattering effects in experimental data processing (the DIRAC experiment [10] like many others [11][12][13]). As the Molière theory is currently used roughly for 1 MeV-200 GeV proton beams [11,14] and extremely high energy cosmic rays and can be applied to investigate the IceCubes neutrino-induced showers [15] with energies above 1 PeV [16], the role of the high-energy CC to the parameters of this theory becomes significant.…”
