SUMMARY:SPS Journal Club: 'Type IIB at Eight Derivatives: A Status Report'
DESCRIPTION:Strings\, Pheno and the Swampland (SPS) Journal Club \nTitle: ‘Type IIB at Eight Derivatives: A Status Report’ \nSpeaker: Raffaele Savelli (Dipartimento di Fisica & INFN\, Università di Roma “Tor Vergata”) \nVenue&Time: Red Room / 11:30 \nAbstract: \nKnowledge of ten-dimensional superstring effective actions beyond the leading order in the derivative expansion is of intrinsic interest and plays a central role in many questions in string phenomenology. For Type IIB string theory\, all the effective couplings are known at the four-point level\, but a complete characterization of the eight-derivative effective action remains elusive. \nIn this seminar\, I will discuss recent progress in deriving the five-point contact terms in sectors that mix gravity with the three-form flux and the axio-dilaton. I will present different approaches to this problem and emphasize the role of SL(2\,Z) duality in constraining the structure of eight-derivative couplings and in revealing universal kinematical patterns. Finally\, I will briefly comment on applications to lower-dimensional physics.\nThe talk is based on arXiv:2205.11530 and arXiv:2507.07934.
