Clay weekly context brief for the High Energy Physics category (ISO week 2026-W31).

Clay tracks publications from the High Energy Physics feed list. Below are recent items from this category, each with its source and a short description of what the publication covers when one is available in the source feed.

Recent publications:
1. The next-to-next-to-leading order BFKL eigenvalue at odd conformal spin in planar N=4 super Yang-Mills
   Source: hep-th (High Energy Physics - Theory)
   Link: https://arxiv.org/abs/2607.17608
   The eigenvalue of the next-to-next-to-leading order BFKL kernel of planar N=4 super Yang-Mills is presented in closed form at odd conformal spin n, as a finite combination of nested harmonic sums, rational functions of the single variable z=(|n|-1)/2 + i nu, and transcendental constants.
2. Cartan Fluxes in $SU(3)$ Lattice Gauge Theory
   Source: hep-lat (High Energy Physics - Lattice)
   Link: https://arxiv.org/abs/2604.25003
   We propose and analyze a new method of detecting center vortices and monopoles in lattice Yang-Mills theory.
3. Forward backward CP asymmetry in $\tau^- \to K \pi \nu_{\tau}$ in the Left-Right Inverse seesaw model
   Source: hep-ex (High Energy Physics - Experiment)
   Link: https://arxiv.org/abs/2604.24924
   The Left--Right Inverse Seesaw (LRIS) model, in which TeV-scale right-handed neutrinos can carry $\mathcal{O}(1)$ Yukawa couplings while light neutrino masses remain protected by a small lepton-number-violating scale, provides a testable link between the neutrino-mass mechanism and flavor and collider observables: the same non-decoupling dynamics has recently been shown to enable viable TeV-scale non-thermal leptogenesis and to explain the $B\to K\mu^+\mu^-$ anomaly.
4. Light deflection in general static and spherically symmetric spacetime with a homogeneous plasma
   Source: gr-qc (General Relativity and Quantum Cosmology)
   Link: https://arxiv.org/abs/2607.22401
   We developed in this work a perturbative technique to compute the deflection angle of light rays in general static and spherically symmetric spacetimes with a homogeneous non-magnetic plasma.
5. Bootstrapping black holes at low impact parameter
   Source: hep-th (High Energy Physics - Theory)
   Link: https://arxiv.org/abs/2607.05503
   We use the stringy dispersion relation (SDR) to ask the following question about gravitational effective field theories: once the universal large-impact-parameter eikonal carrier is supplied, where does the remaining positive spectrum go?
6. Standard Model tests with smeared experiment and theory
   Source: hep-lat (High Energy Physics - Lattice)
   Link: https://arxiv.org/abs/2603.15487
   For Standard Model processes in which on-shell intermediate hadronic states contribute - including inclusive semileptonic decays and long-distance effects in rare exclusive decays such as $D\to \pi \ell\ell$ and $B\to K^{(\ast)}\ell\ell$ - spectral-reconstruction techniques provide a promising route to model-independent lattice QCD predictions for use in phenomenological predictions.
7. Exploring ultra-high energy neutrino experiments through the lens of the transport equation
   Source: hep-ex (High Energy Physics - Experiment)
   Link: https://arxiv.org/abs/2507.10665
   We develop a first-principles formalism, based on the transport equation in the line-of-sight approximation, to link the expected number of muons at neutrino telescopes to the flux of neutrinos at the Earth's surface.

   We ask when a spinless spherical extended test body in vacuum general relativity moves as its point-particle counterpart.
9. Birth of Inflationary Universes via Wineglass Wormholes and their No-Boundary Relatives
   Source: hep-th (High Energy Physics - Theory)
   Link: https://arxiv.org/abs/2605.10548
   We study Euclidean wineglass wormholes, which mediate the nucleation of inflationary spacetimes from an existing spacetime with asymptotically flat or Anti-de Sitter regions.

12. The macroscopic precession model of quasi-periodic oscillations for rotating compact objects
   Source: gr-qc (General Relativity and Quantum Cosmology)
   Link: https://arxiv.org/abs/2607.22322
   The relativistic precession model (RPM) interprets the twin kilohertz quasi-periodic oscillations (QPOs) as geodesic frequencies of test particles orbiting in the spacetime of X-ray binaries hosting either a neutron star (NS) or a black hole.

   The ratio of electronic to muonic leptonic decay widths, $R_{e/\mu}$, for the light mesons $\pi$ and $K$, provides a clean test of lepton flavor universality (LFU) and a sensitive probe of physics beyond the Standard Model.

   A search for a pair of low-mass pseudoscalars $a$ that promptly decay into $\tau$-leptons is presented using 140 fb$^{-1}$ of proton-proton collision data at $13$ TeV centre-of-mass energy recorded with the ATLAS detector at the Large Hadron Collider.
