"Effects of strong electromagnetic field in ultra-relativistic
heavy-ion collisions"
Abstract:
In collisions of relativistic nuclei of gold (the RHIC collider)
or lead (the LHC collider) electric and magnetic fields may exceed
by several orders of magnitude the critical Schwinger field, but
these fields act during a very short time. In such conditions one
can use perturbation theory, but the corresponding parameter
$Z\alpha\approx 0.6$ is not small. It means that the whole series
in $Z\alpha$ has to be summed to obtain the cross section with
sufficient accuracy. In this report I present a small review
about our recent activity related to electromagnetic processes at
the RHIC and LHC colliders. It includes such topics as:
Strong-field effects in the lepton pair production;
Large contribution of the virtual Delbr\"uck scattering into
nuclear bremsstrahlung and Production of bound-free $e^+e^-$ pairs.
