This paper demonstrates that the upcoming MAGIX experiment at the MESA facility can effectively probe light Beyond the Standard Model mediators in the few to hundred MeV mass range by utilizing high-intensity electron beams on a tantalum target to detect Bethe-Heitler pair production, potentially reaching mediator-electron couplings as low as .
This paper proposes a significantly enhanced detection scheme for meV-scale QCD axions and dark photons using highly excited cyclotron states of a trapped electron within an open-endcap trap, achieving background-free sensitivity to the predicted post-inflationary QCD axion mass range (0.1–2.3 meV) and dark photon kinetic mixing parameters as low as through optimized experimental parameters and dielectric-enhanced cavities.
This paper demonstrates that the representations of the Standard Model's lightest particles (excluding the top quark) form a -graded superalgebra isomorphic to the Euclidean Jordan algebra , a structure derived from division algebras that naturally separates internal and spacetime symmetries and potentially bridges particle physics with quantum computing.
This paper proposes and theoretically validates a new method to observe quark effects in nuclei by analyzing in-medium modified nucleon magnetic moments through bremsstrahlung spectra in proton-nucleus scattering, specifically highlighting the potential of using ratios between carbon isotopes like C and C to isolate these effects.
This paper proposes a hybrid neural simulation-based inference approach to constrain the Higgs trilinear self-coupling and other SMEFT operators using off-shell Higgs production at the High-Luminosity LHC, achieving near-theoretical-optimal sensitivity by combining matrix-element-enhanced training with classification-based background estimation.
This paper investigates constraints on ten four-light quark operators in the Standard Model Effective Field Theory by analyzing the interference between Standard Model and new physics contributions in multijet and vector boson fusion processes, while evaluating the sensitivity of differential distributions and the validity of the EFT approach by comparing linear and quadratic contributions.
This paper demonstrates that combining kinetic Sunyaev-Zel'dovich (kSZ) tomography with galaxy clustering significantly improves constraints on dark energy parameters and offers a unique pathway to probe its microphysical perturbations, complementing traditional geometric probes.
This paper demonstrates that while the standard and constraint definitions of a scalar field effective potential are equivalent in Minkowski spacetime, they diverge in de Sitter spacetime, with the constraint potential uniquely avoiding infrared convergence issues and serving as the correct formulation for stochastic Starobinsky-Yokoyama theory.
The ALPS II experiment at DESY conducted its first science campaign from February to May 2024, achieving a 20-fold improvement in sensitivity limits for axion-like particles without finding evidence of their existence, while demonstrating stable operation and preparing for future upgrades to further enhance detection capabilities.
This paper proposes a method for detecting high-frequency gravitational waves (10 kHz–10 MHz) using two-dimensional ion crystals, where resonant excitation of parity-odd drumhead modes is transferred to collective spin rotation via optical dipole forces to generate squeezed spin states that surpass the standard quantum limit, with sensitivity scaling favorably with crystal size and ion number.
