This paper investigates the resonant, exponentially growing production of millicharged scalars in a medium-supported electromagnetic wave background () by reducing the Klein-Gordon equation to the Mathieu equation, ultimately deriving new constraints on these particles based on existing experimental data.
This paper derives a general formula for the energy level contributions of nuclear tensor polarizability in two-body bound systems, demonstrating its role in mixing states of different orbital angular momenta, and specifically evaluates these effects on the hyperfine structure and S-D mixing in muonic deuterium.
This paper presents a precise continuum-limit lattice QCD calculation of heavy meson HQET light-cone distribution amplitudes, achieving a threefold reduction in uncertainty for key inverse moments to significantly improve the theoretical precision of decay predictions and resolve long-standing bottlenecks in flavor physics.
This paper proposes global tripartite entanglement entropy as a robust diagnostic tool for distinguishing the neutrino mass hierarchy and measuring CP violation, demonstrating that MSW matter effects significantly amplify sensitivity and that the optimal energy for hierarchy discrimination remains stable even in the presence of non-standard interactions.
This paper demonstrates that incorporating timing information into LHC searches for new physics, specifically interactions involving ultralight dark matter and quarks, can enhance sensitivity by up to a factor of two compared to traditional methods that assume time-invariant signals.
This paper demonstrates that for a massive spin-3/2 particle, the effective field theory couplings consistent with unitarity and analyticity form a Planck-suppressed, bounded region around the supergravity point that shrinks to zero volume as the mass vanishes, thereby confirming that a consistent massless limit strictly requires the presence of a graviton and supergravity-tuned interactions.
This paper proposes a novel ultra-broadband axion dark matter experiment utilizing a dc SQUID operated at a flux sweet spot with lock-in modulation to achieve unprecedented sensitivity to axion-photon coupling across a mass range spanning over 15 orders of magnitude.
This paper demonstrates that in compact spatial dimensions below a critical volume, false vacuum decay is mediated by a novel homogeneous bounce solution—distinct from Coleman's bubble—that exponentially enhances the decay rate and applies to phenomena such as the Schwinger effect in compact space.
This paper explores a dark matter model where a fermionic dark matter particle simultaneously satisfies existing collider and direct detection constraints while serving as a source for observable charged lepton flavor violation signals, such as and conversion.
This paper proposes a two-loop radiative neutrino mass model based on modular and symmetries that successfully explains neutrino oscillation data and charged lepton masses while predicting observable lepton flavor violation and providing viable scalar and fermionic dark matter candidates consistent with cosmological and experimental constraints.
