Hunting New Physics with Electric Dipole Moments
![The study demonstrates that within a scenario where the gluon charge-electric-dipole moment (CEDM) and down-quark CEDM dominate-specifically at [latex]\Lambda = 10 \text{ TeV}[/latex]-normalization factors ranging from [latex]10^4[/latex] for mercury and xenon to [latex]10^5[/latex] for ytterbium and [latex]10^1[/latex] for radium account for Schiff screening and octupole enhancement, ultimately influencing the observed magnitudes.](https://arxiv.org/html/2604.25516v1/x2.png)
Future measurements of atomic electric dipole moments offer a powerful probe of physics beyond the Standard Model, potentially revealing the origins of matter-antimatter asymmetry.
Unlocking Flavor Secrets: New Insights from Belle and Belle II
![The measured charge-parity (CP) asymmetry in [latex]\tau^{-}\to\pi^{-}K_{S}^{0}\nu_{\tau}[/latex] decays, obtained from Belle II data using electron and muon tags, aligns with Standard Model predictions of approximately [latex]A_{CP}^{SM} = 0.33\%[/latex], confirming expectations after correction for [latex]K_{S}^{0}[/latex] selection efficiency.](https://arxiv.org/html/2604.23757v1/figs/ACP_1.png)
The Belle and Belle II experiments are pushing the boundaries of flavor physics with precise measurements of charmed particles and tau leptons.
Simulating Quantum Magnetism: A Step Closer to Exotic Spin Liquids
![A two-dimensional monomer-dimer model, derived from a Bose-Hubbard system with strong on-site interactions and a staggered potential, facilitates the preparation of a [latex]U(1)[/latex] quantum spin liquid through the conversion of monomers into dimers, a process further refined by suppressing competing processes with a linear tilt and visualized via fluorescence imaging that reveals extended regions of nearly perfect dimer coverings.](https://arxiv.org/html/2604.24744v1/x1.png)
Researchers have used a neutral atom simulator to dynamically create and observe extended regions exhibiting characteristics of a U(1) quantum spin liquid state.
Hunting Beyond Standard Physics with DUNE’s Neutrino Beam
![The search for sterile neutrinos benefits from a multi-channel approach-combining appearance and disappearance signatures-and is poised for significant advancement with DUNE-PRISM, which promises to expand sensitivity beyond current constraints established by experiments like MINOS+, KARMEN, NOMAD, and MicroBooNE, and potentially resolve anomalies suggested by LSND and MiniBooNE results at [latex]99\%[/latex] confidence level.](https://arxiv.org/html/2604.20951v1/x12.png)
A new analysis demonstrates how the DUNE-PRISM program can refine searches for exotic neutrino properties and deviations from known physics.
Beyond Equilibrium: A New Lens on Black Hole Thermodynamics
Researchers are developing a robust framework to understand how black holes behave when perturbed from their static state, moving beyond traditional equilibrium assumptions.
Hunting for New Physics at the Higgs Factory
A new analysis of LHC data is pushing the boundaries of the Standard Model, seeking evidence of physics beyond our current understanding.
Beyond the Ghost: Taming Negative Energies in Quantum Systems
![The study reveals that discrete, equal-parity energy levels-characterized by a configuration [latex] \mathcal{C} = (0,0,0,1) [/latex]-become increasingly sparse away from the diagonal in the [latex] (m,n) [/latex] plane, with near-zero accumulation occurring only along sequences where [latex] (m\_k - n\_k) = \text{const} [/latex] asymptotically.](https://arxiv.org/html/2604.21826v1/x1.png)
New research challenges long-held assumptions about instabilities in quantum mechanics, revealing scenarios where systems with seemingly problematic negative kinetic energy can remain stable and exhibit discrete energy levels.
A New Exotic Meson Emerges from B Meson Decay
![The distribution of candidate [latex]B^{0}[/latex] masses reveals a discernible peak corresponding to the [latex]D_{s}1,3^{*}(2860)^{+}[/latex] state, identified through analysis of the two-dimensional mass distribution of [latex]m(K^{+}\pi^{-})[/latex] versus [latex]m(D^{+}K^{+}\pi^{-})[/latex].](https://arxiv.org/html/2604.21257v1/x3.png)
Scientists have detected a previously unknown excited charm-strange meson, offering fresh insights into the building blocks of matter and the strong force.
