    SUSY, strings, field theory

    The analogy between field redefinitions in EFTs and coordinate transformations suggests that EFT amplitudes can be interpreted as geometric invariants, constructed from fundamental building blocks. We identify these building blocks as geometric quantities derived from the covariant derivatives of the action, which remain covariant in the on-shell limit under derivative-dependent field...

    Modular flavor symmetries in supersymmetric models have been proposed as a new way to address the flavor problem. It is known that they can emerge from string compactifications. We discuss this connection in detail, and show how the congruence subgroups of SL(2,Z), which underlie many modular flavor symmetries, emerge from stringy duality symmetries by orbifolding. We show that, at least in...

    We introduce a formalism for coupling bosonic Continuous-Spin Particles (CSP) to familiar spin-1/2 matter. To do this, we describe the matter using the supersymmetric worldline formalism. We construct currents that are local functions of worldline kinematics, and respect both the worldline supersymmetry and the conservation condition required for consistent couplings to Abelian CSP fields. As...

    In this talk we are going to discuss multiplicities and junctions of BPS domain walls interpolating between different chiral vacua in $\mathcal{N}=1$ supersymmetric QCD (SQCD) with the $SU(N)$ gauge group and a varying number of fundamental quarks. Depending on the number of flavors $F$ two distinct classes of degenerate domain walls emerge: (i) locally distinguishable, i.e. those which differ...

    I will explain how opers and their q-difference analogs help us to understand dualities in supersymmetric gauge theories across various dimensions. Gauged linear sigma models (GLSMs), Super Yang-Mills theories with eight supercharges will appear in the construction. I will also explain the connection with various kinds of integrable systems — spin chains and many-body models.

    I will review developments in applying Anomaly Mediated SUSY Breaking (AMSB) as a theoretical tool for understanding the dynamics of strongly coupled gauge theories. After reviewing the general properties of AMSB, I will show what we have been able to learn when applying it to a variety of examples. Many non-trivial consistency conditions are satisfied. In the case of QCD, I will show how we...

    We study the 2D fermionic SYK model with Majorana fermions, featuring a kinetic term with a quartic expression and a $2q$-body interaction with Gaussian disorder. By minimizing the effective action or solving the SD equation for $q=1$, we determine that the appropriate ansatz involves zero spins. Our computation of the Lyapunov exponent shows violations of chaos and unitarity bounds. The...

    We present an analytical derivation of the chiral symmetry breaking minima in supersymmetric asymptotically-free SU(N) and Sp(N) theories with F flavors of "quarks", perturbed by Anomaly Mediated Supersymmetry Breaking. We are able to show that all such theories, except in the SU(N) case of N = F, possess stable chiral symmetry breaking minima that are plausibly continuously connected to the...

    We present exact results in SU($N_C$) chiral gauge theories with charged fermions in an antisymmetric, $N_F$ fundamental, and $N_C + N_F − 4$ anti-fundamental representations. We achieve this by considering the supersymmetric version of these theories and utilizing anomaly mediated supersymmetry breaking at a scale $m ≪ Λ$ to generate a vacuum. The connection to non-supersymmetric theories is...

    The structure of chiral anomalies in braneworlds is subtle. The divergence of a 5D current has long been known to be localized to end-of-the world branes, and to be evenly divided between these branes. However, such branes may be hidden by horizons, or may even be replaced by soft-wall geometries in certain cases. We demonstrate the correct approach, particularly in models motivated by the...

    In Randall-Sundrum models, the AdS/CFT correspondence motivates the addition of Chern-Simons terms that flow anomalies such that they are entirely localized on the ultraviolet brane. This has interesting implications both for collider physics and for cosmology. We discuss the implications for holographic composite axion solutions to the strong CP problem, and for inflationary cosmology.

    We propose a novel $R_\xi$ gauge in the five-vector (5V) framework within the Abelian Higgs model. In the Cartesian basis of the complex Higgs field, the 5V $R_\xi$ gauge ensures non-divergent tree-level amplitudes for each Feynman diagram in the high-energy limit. This framework pinpoints the origin of high-energy divergences in tree-level amplitudes for each diagram, providing a criterion...
