We propose an exact formula for the energy radiated by an accelerating quark in N=2 superconformal theories in four dimensions. This formula reproduces the known Bremsstrahlung function for N=4 theories and provides a prediction for all the perturbative and instanton corrections in N=2 theories. We perform a perturbative check of our proposal up to three loops.

  1. Do null defects dream of conformal symmetry?

    hep-th 2025-09 conditional novelty 7.0 of 10

    Null line defects preserve a large conformal algebra that constrains their correlators to shockwave-plane discontinuities, and a restricted test-function space resolves the ill-defined ultraboosted gauge potential.

  2. An unusual BPS equation

    hep-th 2025-01 accept novelty 7.0 of 10

    All rotation-invariant superconformal defects satisfy CD/aT = -2(n-1)(p+2)Γ(p+1)/(n π^{p-n/2} Γ(p/2+1)Γ((n-p)/2)), proved from supersymmetric Ward identities.

  3. Bremsstrahlung function in $\mathcal{N}=2$ SCFTs far beyond the supergravity limit

    hep-th 2026-05 unverdicted novelty 6.0 of 10

    Exact large-N and strong-coupling results for Bremsstrahlung function in E-theory and D-theory N=2 SCFTs via matrix models, with closed-form non-perturbative contributions.

  4. Correlators in non-conformal $\mathcal{N}=2$ gauge theories from localization

    hep-th 2025-05 conditional novelty 6.0 of 10

    Two-point correlators of chiral/anti-chiral operators in SU(N) N=2 gauge theories with a non-zero beta function, computed by Feynman diagrams in flat space, match sphere-localization matrix model results exactly throu...

  5. From Weyl Anomaly to Defect Supersymmetric R\'enyi Entropy and Casimir Energy

    hep-th 2025-01 unverdicted novelty 5.0 of 10

    In 6D (2,0) theories, defect supersymmetric Rényi entropy contribution is linear in 1/n and equals a constant times (2b - d2); Casimir energy contribution equals -d2 (up to constant) in the chiral algebra limit.
