This paper investigates how a symmetry-breaking term in composite hybrid inflation triggers a tachyonic instability that generates primordial black holes and a stochastic gravitational wave background, with their specific mass and frequency scales determined by the anomalous dimensions of pion operators and potentially detectable by future observatories.
This paper proposes a universal quantum measurement protocol that extracts the velocity and direction of light dark matter wind from the phase differences between quantum sensors, offering superior sensitivity compared to classical correlation methods without compromising detector performance.
This paper demonstrates that the ionization of dense molecular clouds provides a powerful and competitive method for constraining sub-keV dark matter models that produce UV or X-ray photons through annihilation or decay, with potential for significant improvements through refined observational samples and modeling.
This paper delineates the maximal parameter space for sterile neutrino dark matter by demonstrating that large, flavor-specific lepton asymmetries (with vanishing total asymmetry) can significantly enhance production rates and extend viable mixing angles by up to two orders of magnitude for masses up to 60 keV, while remaining consistent with cosmological constraints.
Using the functional renormalization group method within the two-flavor quark-meson model, this study demonstrates that fluctuation effects significantly lower the critical isospin chemical potential for meson condensation and reveal a phase structure featuring second-order and first-order transitions separating the -dominated phase from other regions.
This paper presents a suite of cosmological simulations incorporating primordial non-Gaussianities from collider physics to characterize their nonlinear signatures in late-time observables and forecasts competitive constraints on these signals using future Vera C. Rubin Observatory weak-lensing data.
This paper demonstrates that weak lensing analysis of future LSST data can provide competitive and complementary constraints on primordial non-Gaussianity models, particularly those with features on small scales, by resolving their signatures in the deeply nonlinear late-time density field through a suite of over thirty templates and new simulations of resonant signatures.
Motivated by LHCb observations, this study employs the perturbative QCD factorization framework to analyze decays into axial-vector and tensor mesons, predicting branching ratios within experimental reach and establishing the dominance of longitudinal polarization amplitudes.
This paper presents updated running quark and lepton Yukawa couplings and mixing parameters across various energy scales within the Standard Model and MSSM frameworks, leveraging the reduced uncertainties in the 2024 Particle Data Group fermion mass determinations to assess their impact on theories beyond the Standard Model.
This paper proposes a protocol for enhancing dark matter detection sensitivity by projecting quantum sensors into a collective excited state, which suppresses non-collective noise by a factor equal to the number of sensors without requiring the maintenance of entanglement during signal accumulation.
