Description
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.
