This paper investigates how dark matter capture, alongside mergers and gas accretion, can facilitate the rapid growth of supermassive black holes by , finding that while standard cold dark matter contributes insignificantly, scenarios involving dark matter clustering or ultralight dark matter can enable stellar-mass seeds to reach masses exceeding .
This paper computes all possible medium-induced single-scattering emission kernels for an energetic virtual quark traversing a nuclear environment at next-to-leading order and next-to-leading twist, incorporating heavy-quark mass effects, Glauber quark and gluon interactions, and coherence effects to derive four distinct collisional scattering kernels with full phase factors and gradient expansions.
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 summarizes recent observations of high and ultrahigh energy neutrinos, including the detection of a diffuse cosmic background, candidate sources, and Galactic plane emissions, which collectively establish neutrinos as a unique tool for probing inaccessible cosmic phenomena despite the ongoing uncertainty regarding the origins of most detected events.
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.
