Photon polarization as a probe for quark-gluon plasma dynamics
Andreas Ipp, Antonino Di Piazza, Jörg Evers +1
Prospects of measuring polarized photons emitted from a quark-gluon plasma (QGP) are discussed. In particular, the detection of a possible quark spin polarization in a QGP using ci…
Non-perturbative vacuum-polarization effects in proton-laser collisions
A. Di Piazza, K. Z. Hatsagortsyan, C. H. Keitel
In the collision of a high-energy proton beam and a strong laser field, merging of the laser photons can occur due to the polarization of vacuum. The probability of photon merging…
Production of light particles by very strong and slowly varying magnetic fields
Giorgio Calucci, Antonino Di Piazza
The possibility that around some astrophysical objects there are non-static magnetic fields of enormous intensity suggests that in these situations real particles may be produced.…
Photon splitting in a laser field
A. Di Piazza, A. I. Milstein, C. H. Keitel
Photon splitting due to vacuum polarization in a laser field is considered. Using an operator technique, we derive the amplitudes for arbitrary strength, spectral content and polar…
