#### Comments on the Space of QFTs

Regular Seminar Matthew Buican (Queen Mary University of London)

 at: 13:15 KCLroom G01 Norfolk Building abstract: In the first part of the talk, I will revisit the question of how to decide whether two 4D N=2 superconformal field theories describe the same physics. Time permitting, I will discuss related questions regarding the classification of 2D rational conformal field theories.

#### Graduate Mini-Course: Sectors of Supersymmetric Field Theories

Informal Seminar Matthew Buican (QMUL)

 at: 10:30 QMWroom GOJ 610 abstract: Lecture 3: "Toward a Synthesis of Chiral Rings and Chiral Algebras." I will aim to discuss some recent work that seeks to relate the objects introduced in the first two lectures. Given enough time, we may also discuss generalizations of these ideas.

#### Graduate Mini-Course: Sectors of Supersymmetric Field Theories

Informal Seminar Matthew Buican (QMUL)

 at: 10:30 QMWroom GOJ 610 abstract: Lecture 2: "Chiral Algebras and Higher-Dimensional Theories." I will review briefly review the construction of chiral algebras and then focus on their relationship with a particular sub-sector of operators in higher-dimensional theories. I will again focus mostly on 4D N=2 theories.

#### Graduate Mini-Course: Sectors of Supersymmetric Field Theories

Informal Seminar Matthew Buican (QMUL)

 at: 10:30 QMWroom GOJ 610 abstract: Lecture 1: "Chiral Rings, Moduli Spaces, and Conformal Manifolds." In this lecture I will review basic aspects of chiral operators, with a special focus on 4D theories with 8 Poincare supercharges (i.e., N=2 SUSY). Using these operators, I will discuss basic aspects of moduli spaces and conformal manifolds.

#### SUSY Breaking in N=2 QFT

Regular Seminar Matthew Buican (CERN)

 at: 14:00 QMWroom 602 abstract: We will show that a large class of N=2 SUSY field theories do not have SUSY breaking vacua.
