Abstract Lego - building 5d SCFTs from M-theory on Calabi-Yau threefolds

Oscar Lewis

Abstract

Placing M-theory on a non-compact Calabi-Yau threefold allows us to construct low energy field theories in 5d with minimal supersymmetry, in a limit in which gravity is decoupled. We venture into this topic by introducing all the building blocks we hope to capture in a 5d SCFT. Next, from the geometric perspective we realise the 5d gauge theory data from the objects within the Calabi-Yau geometry, given by curves, divisors, rulings, and singularities. After seeing how the geometry captures all the possible field theory data, we illustrate how to build some simple 5d SCFTs by placing M-theory on toric Calabi-Yau threefolds.

Junior Strings is a seminar series where DPhil students present topics of common interest that do not necessarily overlap with their own research area. This is primarily aimed at PhD students and post-docs but everyone is welcome.

A general hierarchy of charges for sub-leading soft theorems at all orders

Giorgio Pizzolo

(Durham University)

Abstract

The deep connection between the soft limits of scattering amplitudes and asymptotic symmetries relies on the construction of a well-defined phase space at null infinity, which can be set up perturbatively via an expansion in the soft particle energy. At leading order, this result has by now been established.

In this talk, I will present a new general procedure for constructing the extended phase space for Yang-Mills theory, based on the Stueckelberg mechanism, that is capable of handling the asymptotic symmetries and construction of charges responsible for sub-leading soft theorems at all orders. The generality of the procedure allows it to be directly applied to the computation of both three- and loop-level soft limits. Based on [2407.13556] and [2405.06629], with Silvia Nagy and Javier Peraza.
