The String Theory Swampland

09.11.2018 14:15 – 15:15

How many string theory vacua are consistent with the real world? Claimed answers to this range between
0 and 10^500. Critical to determining an answer is the ability to understand what constraints quantum
gravity imposes on low-energy Lagrangians. In this talk I review the constructions of quasi-realistic
string models and the so-called swampland conjectures on how their properties are constrained by
quantum gravity. I also describe work in progress on CFT_3 duals of AdS_4 moduli stabilisation
scenarios, which in the context of the Large Volume Scenario leads to sharp statements about the
conformal dimensions of low-lying single trace operators and the form of their higher-point
interactions. I finally describe possible relations between swampland constraints on consistent quantum
gravity theories and bootstrap constraints on consistent conformal field theories.
