Evading the CMB μμ-distortion bound on Supermassive Primordial Black Hole seeds with Non-Gaussian tails

This paper demonstrates that the CMB μ\mu-distortion bound, which typically precludes the formation of supermassive primordial black hole seeds via Gaussian perturbations, can be evaded by invoking non-Gaussian probability distribution tails—specifically power-law or sufficiently heavy log-normal shapes—that decouple the small-scale variance from the collapse probability.

Hardware-efficient quantum simulation of intense-field QED

This paper proposes a hardware-efficient trapped-ion protocol for simulating nonperturbative intense-field QED in 3+1 dimensions by encoding photon modes in collective phonons and Volkov-dressed fermions in ion spins, demonstrating that zero-noise extrapolation can effectively mitigate experimental noise to accurately benchmark nonlinear Breit–Wheeler pair production.

Darkly Charged ALPs

This paper extends the standard axion-like particle (ALP) framework by constructing an effective Lagrangian for ALPs carrying conserved dark charges, demonstrating that such particles cannot couple to Standard Model fields via dimension-5 operators and instead require dimension-6 interactions, while exploring their phenomenological implications and potential role as dark matter.

Benchmarking the Nearside Energy-Energy Correlators with Mellin Transform

This paper presents a Mellin-transform framework that successfully describes nearside energy-energy correlators in e+e−e^+e^- annihilation across perturbative and post-confinement regimes using a single transition scale parameter Λ\Lambda, achieving excellent agreement with experimental data from ALEPH and earlier measurements at next-to-next-to-leading-order accuracy and next-to-next-to-leading-logarithmic resummation.

The Higgs boson through the lens of electroweak precision data

This paper presents an updated global electroweak fit incorporating the latest WW-boson mass and Higgs signal-strength measurements to confirm the Standard Model's internal consistency, derive indirect constraints on Higgs couplings and width, and establish bounds on invisible decays and Wilson coefficients while projecting future precision at the FCC-ee.

Strong First-Order Electroweak Phase Transitions and Gravitational Waves in the Normal Two-Higgs-Doublet Model: A Comparative Study of the Four Yukawa Types and Thermal Resummation Schemes

This paper presents a global analysis of strong first-order electroweak phase transitions and associated gravitational waves in the Normal Two-Higgs-Doublet Model, revealing that while both the Parwani and Arnold-Espinosa thermal resummation schemes favor the Higgs alignment limit, the Arnold-Espinosa prescription severely restricts the viable parameter space and heavy-scalar mass scales compared to the more stable Parwani approach, thereby highlighting the critical role of theoretical scheme choices in predicting observable signals for future experiments like LISA and colliders.

QED vertex and anomalous magnetic moment in the presence of a magnetic field

This paper computes the one-loop fermion-photon vertex in QED under a constant magnetic field, revealing how the background breaks Lorentz and time-reversal invariance to induce a complex tensor structure with direction-dependent anomalous magnetic moments, specific Landau level selection rules, and an infrared-regulated framework that eliminates the need for a photon mass.

Matter Profile Mismodeling as the Origin of the CP CPT Degeneracy in Long-Baseline Neutrino Oscillation

This paper demonstrates that approximating Earth's density as a constant value in long-baseline neutrino experiments creates a geometric artifact indistinguishable from genuine CPT violation and CP phase shifts, proving that full spatially resolved density modeling is a strict mathematical necessity to avoid false BSM discoveries.
