This paper determines the minimum thrust required for various N-particle configurations, presenting a novel exact solution for N=5 in three dimensions and utilizing numerical optimization alongside Extreme Value Theory for larger systems across multiple spatial dimensions.
This paper introduces a general framework of spinning energy correlators that captures the full angular momentum structure of scattering events, demonstrating their boundedness via unitarity, calculating them in QCD to reveal enhanced infrared insensitivity, and extending sum rules to include conserved charges.
This paper investigates finite-temperature SU(2) Yang-Mills theory under imaginary rotation using the background-field method, demonstrating that such rotation modifies the chromomagnetic condensate and Polyakov loop, partially suppresses the Nielsen-Olesen instability, strengthens the effective coupling at high temperatures, and induces a negative contribution to the moment of inertia.
This paper constructs a high-temperature effective field theory for gauge-Higgs models up to by performing three-loop matching to derive improved scalar and Debye masses and quartic couplings, demonstrating that one-loop dimension-six operators dominate thermodynamic corrections relevant for gravitational-wave observables while identifying previously missing contributions to master integrals and the QCD Debye mass.
This paper demonstrates that the explosive relativistic expansion of the Quark-Gluon Plasma naturally suppresses vortex amplification through geometric dilution, leading to a near-vanishing global hyperon polarization and necessitating azimuthal differential measurements to detect the medium's extreme vorticity.
This paper demonstrates that nonlocal quantum field theories avoid the fermion doubling pathology because the invertibility of their entire-function operators preserves the kernel of the original Dirac operator, thereby rendering the Nielsen-Ninomiya theorem inapplicable to this nonlocal, non-compact framework.
This paper presents a model-independent search for light charged Higgs bosons (110–165 GeV) produced via rare top decays () followed by the off-shell decay , establishing new constraints on this previously unconstrained channel by reinterpreting ATLAS dileptonic measurements and demonstrating its competitive sensitivity in specific two-Higgs-doublet scenarios near the top-quark mass threshold.
This paper presents a precision analysis of semileptonic and non-leptonic meson decays into P-wave charmonium states, utilizing NRQCD-based form factors constrained by experimental radiative decay data to provide updated predictions for branching fractions and lepton flavor universality ratios.
This paper proposes that axion-like particles (ALPs) induce a distinctive asymmetric Fano-type resonance in linear Breit-Wheeler pair production through interference with standard QED amplitudes, offering a novel experimental probe for MeV-scale ALPs in a kinematic region inaccessible to other search methods.
The paper concludes that direct-detection blind spots cannot rescue stable light higgsino dark matter in natural supersymmetry models, as the surviving blind spots lie in unnatural parameter regions or are excluded by LHC and Higgs mass constraints, thereby favoring models with unstable light higgsinos.
