Electroweak corrections to $τ^{+} τ^{-}$ production in ultraperipheral heavy-ion collisions at the LHC

Stefan Dittmaier, Tim Engel, Jose Luis Hernando Ariza +1

While the anomalous magnetic moments of the electron and the muon have been measured with remarkable precision, the magnetic moment of the $τ$ -lepton is only known to rather limite…

Multiple soft-photon emission at next-to-leading power to all orders

Tim Engel

This paper derives a next-to-leading power (NLP) soft theorem for multi-photon emission to all orders in the electromagnetic coupling constant, generalising the leading-power theor…
