Photon conversion to axions and dark photons in magnetized plasmas: a finite-temperature field theory approach
Published 2024-12-01“…In this work, we provide a general formalism for determining the normal modes of propagation that are coupled to axions and dark photons in an anisotropic plasma. As a key part of this formalism, we present detailed derivations of Π μν for magnetized plasmas in the long-wavelength limit using the real-time formalism of finite-temperature field theory. …”

Dimuon and ditau production in photon-photon collisions at next-to-leading order in QED
Published 2025-02-01“…The NLO terms are found to modify the total fiducial cross sections by up to 5%, increasing the tails of the dilepton acoplanarity and transverse momentum distributions, and depleting by up to 15% the yields at high masses, with respect to the leading-order predictions including the very small virtuality of the colliding photons. At the LHC, the calculations obtained with the charge form factor for protons and lead ions including the NLO QED corrections improve the data-theory agreement for all measured differential distributions, and prove an indispensable ingredient for the extraction of precision quantities in photon-photon processes, such as the anomalous magnetic moment of the tau lepton.…”
