Hep-Th, or high-energy theoretical physics, explores the fundamental building blocks of our universe and the forces that govern them. Researchers in this field use complex mathematics to understand everything from subatomic particles to the behavior of black holes, often pushing the boundaries of what we know about space and time.

This paper employs on-shell three-point bootstrap techniques, utilizing massless helicity spinors and discrete symmetry representations, to derive Weyl, chiral, diffeomorphism, and Lorentz anomalies up to constant prefactors while recovering gauge-anomaly cancellation conditions and establishing that Weyl anomalies do not involve Pontryagin densities.
By dynamically coupling the quark gap equation to the full non-perturbative quark-gluon vertex, this study reveals that sub-GeV time-like momenta yield a pair of real poles with opposite-sign residues—governed by a dominant triplet of vertex form factors—thereby resolving the conceptual issues of complex conjugate poles while maintaining consistency with color confinement.
This paper computes the classical gravitational Compton amplitude at the fourth post-Minkowskian order () using the Worldline Quantum Field Theory framework, derives the corresponding -matrix element for gravitational-wave scattering phase shifts, and validates the results against black-hole perturbation theory.
This paper generalizes the study of fermions coupled to light scalar fields in cosmological backgrounds with a constant equation of state, identifying distinct scaling and asymptotic regimes driven by approximate scale invariance to establish a foundation for analyzing perturbation growth and potential early structure formation.
This paper introduces a simple geometric "South-East" rule algorithm that determines which critical points contribute to the asymptotic evaluation of multidimensional integrals with exponential integrands, thereby eliminating the need for complex flow computations required by traditional Picard-Lefschetz methods and offering a systematic approach to identifying instanton contributions in real-time path integrals.
This paper constructs a new smooth 4-manifold invariant and an embedding into the hyperfinite II₁ factor that induces a Riemannian metric and "Hodge dynamics," demonstrating that the metric satisfies the Riemannian vacuum Einstein equation if and only if its curvature tensor lies in the fixed-point subalgebra of this dynamics, while also classifying these representations through the lens of thermal equilibrium states in algebraic quantum field theory.
This paper utilizes a topologically-twisted 8d gauge theory on Spin(7)-manifolds to construct novel gauge-theoretic Floer homologies and categorifying -categories for manifolds of dimensions two through seven, thereby providing physical proofs and generalizations of long-standing conjectures in Donaldson-Thomas theory and related fields.
This paper demonstrates that weakly coupling two chiral SYK models in 1+1 dimensions via a relevant interaction preserves the gapless nature and entropy of the individual systems, leading to massless collective modes and quasiparticle tunnelling without a mass gap or thermal phase transition, thereby highlighting a sharp qualitative distinction from the behavior of coupled SYK models in 0+1 dimensions.
This paper demonstrates that 't Hooft anomalies in higher-form symmetries cause brane partition functions on closed manifolds to vanish due to net background charges or non-trivial anomalous phases, a framework used to derive Freed-Witten-like anomaly cancellation conditions for M5-branes and D3-branes in S-fold backgrounds.
This paper challenges the conclusions of Aoki, Fukaya, and Taniguchi regarding the vanishing of the Dirac spectral density and topological susceptibility in the chirally symmetric phase, arguing that a critical step in their proof is unjustified and their results require reassessment.
