Popis:	Susceptibilities of conserved charges such as baryon minus lepton number enter baryogenesis computations, since they provide the relationship between conserved charges and chemical potentials. Their next-to-leading order corrections are of order g, where g is a generic Standard Model coupling. They are due to soft Higgs boson exchange, and have been calculated recently, together with some order g^2 corrections. Here we compute the complete g^2 contributions. Close to the electroweak crossover the soft Higgs contribution is of order g^2, and is determined by the non-perturbative physics at the magnetic screening scale. Comment: 18 pages, 2 figures
