This paper demonstrates that including second-order corrections in the bubble nucleation rate expansion is essential for accurately predicting primordial black hole abundances and gravitational wave spectra in realistic models, as these corrections alter the fluctuation distribution toward Gaussianity and decouple PBH yields from GW signals.
This paper derives the probability for chiral oscillation of Majorana neutrinos within quantum field theory by utilizing the Bogoliubov transformation to relate lepton number eigenstates at different times, thereby characterizing the time variation of lepton number as a transition amplitude.
This paper investigates the interplay between dark matter scattering and light mediator absorption in direct detection experiments for Dirac and atomic dark matter models, identifying viable parameter spaces constrained by cosmology and astrophysics while highlighting the importance of distinguishing these signals to uncover the underlying physics.
Using the three-fluid dynamics model, this study calculates global polarization in Au+Au collisions at high baryon densities (3–9 GeV), successfully reproducing STAR data at 3 GeV and predicting a broad maximum in polarization around 3–3.9 GeV while analyzing the specific contributions of thermal vorticity, meson fields, thermal shear, and the spin-Hall effect.
This paper presents a detailed background mitigation analysis for the DUNE near detector, evaluating its capability to constrain or discover long-lived beyond-Standard-Model particles by investigating hard electromagnetic signatures in , , , and final states while accounting for realistic neutrino-induced backgrounds and detector effects.
This paper proposes a fermionic dark matter model within a hidden gauge sector that successfully accounts for the observed relic density and evades direct detection bounds while simultaneously resolving the hierarchy problem by satisfying Veltman conditions at the TeV scale through the contributions of new scalar, spinor, and vector fields.
This paper reviews the progress of the ESCAPE Dark Matter Test Science Project, highlighting its development of tools to bridge the gap between particle physics experiments and astrophysical observations to foster interdisciplinary collaboration in the search for dark matter.
This study employs open quantum system methods and Arnoldi iterations to analyze Krylov complexity and entropy in the early universe, revealing that while non-trivial sound speed yields similar complexity trends to the standard case, it induces distinct entropy evolution and maximally chaotic behavior characterized by specific Lanczos coefficients.
Using a three-fluid dynamics model with a crossover equation of state, this paper predicts a non-monotonic evolution of proton directed flow in Au+Au collisions between 4.5 and 7.7 GeV, characterized by a sign change and minimum at 7.2 GeV that signals the onset of the transition to quark-gluon plasma.
This paper emphasizes the critical impact of modeling the Large Magellanic Cloud's dynamics on the local dark matter velocity distribution for high-mass searches, introducing new computational techniques to re-evaluate bounds from cosmic ray and magnetic monopole experiments at the Ohya Mine and Skylab.
