In this particular occasion the SPLE-Club will take place in the Red Seminar room. The plan is

11:30 - 12:30 seminar by Pierre Corvilain "Swampland, Anomalies and Infinite Distances"

12:30 - 13:00 discussion of papers

Abstract of the seminar:

We explore different consistency conditions that EFT's consistent with quantum gravity must satisfy, including both anomalies and swampland constraints. We start by verifying that EFTs from F-theory are anomaly free. To do so, one is led to consider the behaviour of anomalies on a circle. We find that, after circle reduction, chiral anomalies are captured by field-dependent Chern-Simons terms. In order to see this, one has to use a regulator that preserves the symmetries of the higher dimensional theory. We proceed with a discussion of the Swampland Distance Conjecture, which states that when going to points at infinite distance in moduli space, an infinite tower of states becomes light. Recently there has been some successful tests of this conjecture in string-theory compactifications. We continue along these lines and test the conjecture in the Kaehler moduli space of M-theory on a Calabi-Yau three-fold. At the large volume point, which lies at infinite distance, we identify the tower of light states as being wrapping M2-branes. We further find that these states are mapped to KK-modes at the F-theory point.

ERC-SPLE organizes a bi-weekly journal club, the SPLE-club, in which IFT members and visitors interested in string model building and related topics gather to discuss recent papers, new results, and enjoy interesting expositions by participants.
