This paper investigates how first-order phase transitions in accreting proto-neutron stars generate simultaneous gravitational waves in the kHz and MHz bands alongside a delayed neutrino burst, offering a unique multi-messenger signature to constrain nuclear matter and phase transition physics.
This paper extends a diabatic framework for charmonium-like mesons by incorporating the complex scaling method to treat bound and resonant states on equal footing, thereby enabling parameter-free extraction of decay widths and revealing significant molecular characteristics in states such as , , and while proposing as a candidate.
Using first-principles nonequilibrium Kadanoff-Baym equations, this paper demonstrates that plasma effects suppress collisional freeze-in by replacing the vacuum mixing angle with a plasma-corrected counterpart, thereby ruling out keV-MeV sterile neutrinos as dark matter produced from the Standard Model plasma.
This paper demonstrates that a massive spectator field in de Sitter space coupled to a spatially quenched random source with a power-law time profile yields an exactly solvable model where disorder averaging modifies only the statistical sector of the propagator, resulting in a cosmological collider signal that factorizes into hypergeometric components with a clock frequency fixed by the heavy-field mass but an amplitude and phase controlled by the temporal profile.
This essay defends the Future Circular Collider (FCC) against climate-related criticisms by arguing that the project's scientific value and potential societal benefits outweigh its environmental costs, urging a shift from a mindset of renunciation to one of transformative innovation.
This paper computes the two-loop contributions to Higgs production via gluon-gluon fusion and decay into two photons arising from third-generation four-quark operators in the SMEFT, performed in the broken phase with full mass dependence to derive finite matching corrections, renormalization group effects, and new two-loop anomalous dimensions.
This paper proposes using highly sensitive quantum devices, such as superconducting qubits and trapped ions, to detect the faint electromagnetic signals from radiative decays of cosmic neutrinos and dark matter, demonstrating that current technology can probe dark matter candidates while future scalable architectures are needed to exceed limits on neutrino magnetic moments.
This paper proposes a classically conformal hidden extension of the Standard Model that predicts a suppressed decay width testable at the ILC, while identifying parameter regions where the associated strong first-order phase transition generates gravitational wave signals detectable by future observatories, despite the hidden gauge boson dark matter candidate being excluded by current direct detection limits.
This paper develops and validates a wavefunction-based one-dimensional Cornell-type double-well model for calculating proton tunneling splittings, demonstrating its effectiveness as a benchmarking tool by accurately reproducing the tunneling splitting of the formic acid dimer while highlighting the pedagogical value and limitations of simplified models compared to full multidimensional quantum treatments.
This review paper summarizes a decade of theoretical and experimental advances in muon physics, highlighting enhanced sensitivities in measuring muon properties and searching for new phenomena to probe physics beyond the Standard Model, including light new particles and hidden sectors, while discussing future opportunities for novel experimental concepts and facilities.
