In this study, we compute the non-singlet contribution from intermediate Euclidean current separations in quantum chromo- and electrodynamics (QCD+QED) using C⋆ boundary conditions in two ways: either non-perturbatively by sampling the joint probability distribution directly or by perturbatively expanding from an isospin-symmetric theory. This allows us to compare the predictions and their uncertainties at a fixed lattice spacing and volume, including fully the sea quarks effects in both cases. Treating carefully the uncertainty due to tuning to the same renormalized theory with Nf = 1 + 2 + 1 quarks, albeit with unphysical masses, we find it advantageous to simulate the full QCD+QED distribution given a fixed number of samples.

The chaotic nature was revealed concretely through a matching among the vacuum Virasoro block in holographic CFT2, ETH analysis, and gravitational on-shell partition function in AdS3 with nontrivial backreaction. In this work, we generalize this matching in two ways. First, we compute two-point correlator of the spinning defects, in contrast to previous scalar defect correlator, in both the microcanonical ensemble and the canonical ensemble. Holographically, these spinning defects correspond to bulk domain walls composed of dust particles with angular momentum. Using the first order formalism of gravity, it is shown that the junction condition deviates from Israel’s junction condition, resulting in a discontinuous metric across the domain wall. Second, we calculate general higher point correlators involving multiple scalar defects and provide a detailed example with four defects. We see explicitly that, because line operators in CFT2 are codimension one objects, the correlators depend on the order in which these nonlocal defects are inserted, unlike the Euclidean correlators of local operators. In both generalizations, we achieve a precise matching between field theory solutions, ETH analysis and gravitational on-shell actions.","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2025 10","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP10(2025)161.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145316322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All diagrams involving internal photons are evaluated in coordinate space, employing a Pauli-Villars-regulated photon propagator with a cutoff scale Λ well below the lattice cutoff. The counterterm (mu – md), whose Λ dependence is consistent with the expected logarithmic behaviour, is calibrated using the experimental kaon mass splitting as input. The bare electromagnetic contribution at fixed Λ is compared to a phenomenological estimate based on the kaon-loop and pseudoscalar-pole contributions to the forward light-by-light amplitude. An extension of these calculations to physical pion and kaon masses appears promising.","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2025 10","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP10(2025)157.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145316536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This implies the resummation of all corrections that scale like powers of αs/v (where v is the velocity of the top quark in the ( toverline{t} ) rest frame) which are dominated by values of v of order αs. In this work, we show that, since the observables that are usually considered for these studies are integrated cross sections up to a ( toverline{t} ) mass cut that is not small, it is possible to perform the calculation using perturbation theory, considering only the contributions that scale as the first few powers of αs/v. We examine the implications of our approach by computing corrections to nominal Monte Carlo results for correlation-sensitive observables, and compare them with available data, showing that the tension with data is no longer present.","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2025 10","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP10(2025)149.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145315713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this mechanism typically requires large axion-dark photon couplings or some degree of fine-tuning. In this work, we present a new scenario in which efficient dark photon production arises from axion potentials that are shallower than quadratic at large field values. For moderately large initial misalignment angles, the oscillation of the axion field can trigger either efficient dark photon production or strong axion self-resonance via parametric resonance. When self-resonance dominates and disrupts the field’s homogeneity, we show that oscillons — localized, oscillating axion field configurations — naturally form and can sustain continued dark photon production, provided the coupling is ≳ ( mathcal{O}(1) ). For dark photon mass up to three orders of magnitude below the axion mass, the produced dark photons can account for a significant fraction of the present-day dark matter. We support this scenario with numerical lattice simulations of a benchmark model. Our results further motivate experimental searches for ultralight dark photon dark matter.

Building on our previous work, this result establishes that these theories ultimately originate from 6d (mathcal{N}=(1, 0)) orbi-instanton theories compactified on a torus. The requisite 4d mass deformations are realized as tractable Fayet-Iliopoulos deformations on the 3d mirror quiver. The core of our method is a constructive procedure that utilizes the Euclidean algorithm to define a chain of deformations connecting different Dp(SU(N)) theories. By reversing this chain, we recursively build a “parent” star-shaped quiver for any given (N, p). This quiver is the 3d mirror theory of the required class (mathcal{S}) ancestor. We substantiate our general claims with several detailed examples that explicitly illustrate the deformation procedure.","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2025 10","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP10(2025)155.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145315711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
