abstract

We show that near the edges of the conformal window of supersymmetric $SU(N_c)$ QCD, perturbed by Anomaly Mediated Supersymmetry Breaking (AMSB), chiral symmetry can be broken depending on the initial conditions of the RG flow. We do so by perturbatively expanding around Banks--Zaks fixed points and taking advantage of Seiberg duality. Interpolating between the edges of the conformal window, we predict that non-supersymmetric QCD breaks chiral symmetry up to $N_f \leq 3N_c - 1$, while we cannot say anything definitive for $N_f \geq 3N_c$ at this moment.

  1. Truly Confining Supersymmetric Gauge Theories

    hep-th 2025-05 conditional novelty 7.0 of 10

    The authors propose a complete list of seven truly confining supersymmetric gauge theories and show that each exhibits magnetic operator condensation and discrete symmetry breaking, including two new models.

  2. A High-Quality Composite Pati-Salam Axion

    hep-ph 2025-05 conditional novelty 7.0 of 10

    A new composite axion model in which the Pati-Salam gauge group emerges from strong dynamics, yielding a high-quality accidental PQ symmetry and a fixed axion-photon coupling ratio E/N = -7/3.

  3. Dynamics of $E_6$ Chiral Gauge Theories

    hep-th 2025-05 conditional novelty 7.0 of 10

    E6 gauge theories with NF=1,2,3 fundamentals are solved in the near-supersymmetric limit, and NF=3 admits a vacuum with unbroken SU(3) and massless composite fermions in the 10 representation.

  4. Phase Transitions at Unusual Values of $\theta$

    hep-th 2025-06 conditional novelty 6.0 of 10

    Using Seiberg-Witten theory plus anomaly mediation, the authors find first-order phase transitions in the theta-dependent vacuum energy at theta = pi (N_F=0), 0 and pi (N_F=1), pi/2 and 3pi/2 (N_F=2), and pi/4, 3pi/4,...

  5. To Break or Not to Break: A Review of a No-Go Theorem on Chiral Symmetry Breaking in QCD-like Theories

    hep-ph 2025-09 conditional novelty 2.0 of 10

    A review showing that if a QCD-like theory with enough massless flavors is fully color-screened in the infrared, then chiral symmetry must be spontaneously broken.
