Technically Natural Suppression of Fifth Force

This paper proposes a Z2Z_2-symmetric mirror extension of the Standard Model within a bi-conformal gravity framework where spontaneous scale invariance breaking generates a light scalaron that naturally suppresses fifth-force couplings via symmetry, predicting a specific correlation between the force strength and scalar mass that aligns with next-generation experimental targets without relying on environmental screening mechanisms.

Baryon-Meson Sum Rule for b→sννˉb \to s \nu\bar\nu

This paper establishes a model-independent sum rule linking the branching fractions of Λb→Λννˉ\Lambda_b \to \Lambda \nu\bar\nu and B→K(∗)ννˉB \to K^{(\ast)} \nu\bar\nu decays, which remains exact despite numerous Wilson coefficients and shares numerical coefficients with the b→cb\to c semileptonic counterpart, thereby providing a powerful tool to discriminate new-physics scenarios involving left-handed neutrinos.

Prospects of boosted magnetic dipole inelastic fermion dark matter at ILC-BDX

This paper investigates the projected sensitivity of the Beam-Dump eXperiment at the International Linear Collider (ILC-BDX) to inelastic fermionic dark matter coupled via an off-diagonal magnetic dipole operator, demonstrating that the experiment can probe a phenomenologically relevant parameter space for both 1-year and 10-year data-taking scenarios with specific mass splittings.

The phase diagram of confining holographic theories on constant curvature manifolds in the presence of a θ\theta-angle

This paper investigates the phase diagrams of confining holographic theories on constant curvature manifolds with a θ\theta-angle, revealing that negative curvature manifolds exhibit no phase transitions while positive curvature manifolds display both first and second-order phase transitions, alongside a proof of a holographic Vafa-Witten-like theorem for the θ=0\theta=0 case.

Charged-Current Neutrino-Induced Single-Pion Production in the Superscaling Approach and Relativistic Distorted-Wave Impulse Approximation

This paper presents a detailed comparison of the SuSAv2 and RDWIA theoretical models against experimental measurements of charged-current neutrino-induced single-pion production from T2K, MINERvA, and MiniBooNE across a broad energy range, highlighting their respective approaches to modeling nuclear targets and pion production channels.

Collective excitations in magnetic topological insulators and axion dark matter search

This paper investigates collective excitations in magnetic topological insulators and finds that one identified "axionic" quasi-particle has an electromagnetic coupling that is either unchanged or suppressed by up to two orders of magnitude compared to previous estimates, significantly altering the sensitivity prospects for axion dark matter searches using these materials.

Observable CMB B-modes from Cosmological Phase Transitions

This paper demonstrates that tensor perturbations generated during first-order cosmological phase transitions in a secluded dark sector can produce observable CMB B-mode signals comparable to inflationary predictions, potentially complicating the interpretation of future data but offering a way to distinguish the two scenarios through multi-scale measurements.

Muon Beam Dump Experiments explicate five-dimensional nature of U(1)Lμ−LτU(1)_{L_{\mu}-L_{\tau}}

This paper investigates how present and future muon beam dump experiments can probe the five-dimensional nature of U(1)Lμ−LτU(1)_{L_\mu-L_\tau} interactions by leveraging the enhanced signals from multiple Kaluza-Klein gauge bosons and their distinct decay channels to provide direct evidence for extra dimensions while constraining parameters via the muon (g−2)(g-2) anomaly.
