String Theory seminar - Rishi Mouland Seminar

Abstract: I will discuss recent work investigating five-dimensional field theories with an SU(1,3) geometric symmetry. I will demonstrate the constraining power of the symmetry group—which includes a Lifshitz scaling—and in particular present the solutions to the conformal Ward identities for correlators. The utility of these theories in the construction of 6d CFTs will be discussed, along with an explicit Lagrangian example with a large degree of supersymmetry. Time permitting, I hope to contextualise these results within M-theory (in particular the DLCQ proposal for the M5-brane), and also within the AdS7/CFT6 correspondence. Based on: 1) N. Lambert, A.
