CPT Student Seminar: Generalised global symmetries of field theories

Presented by Sophie Hosseini, Durham University
26 October 2020 15:00 in Zoom (Meeting ID: 931 4876 1099 Passcode: 685500)

Symmetry is one of the most useful and fruitful tools in the analysis of quantum field theory. In the recent months, there has been a rapidly growing interest in generalised global symmetries, also known as higher form symmetries. In this talk I will introduce the concept of higher form symmetries by first recalling the definition of ordinary global symmetries and then generalising it. I will then discuss the example of 4d Yang-Mills theory to further elaborate. In the second part of the talk, I will explain how higher form symmetries can be found systematically from geometric engineering and how flux non-commutativity in type IIB results in mixed ’t Hooft anomalies for the defect group which constrain the global structures of the corresponding field theories.
