This paper resolves discrepancies in the literature regarding ultraviolet divergences in cosmological correlators by demonstrating that various renormalization schemes yield consistent, unitary results and establishing a practical framework where the imaginary part of one-loop wavefunction coefficients is universally fixed by the logarithmic running of the real part.
This paper extends the gradient expansion formalism to fermionic axion inflation, demonstrating that Schwinger pair creation of charged fermions damps gauge-field production and attenuates the gravitational wave signal, thereby allowing observable signals from LISA and ET to be compatible with constraints while identifying a new damped oscillatory backreaction regime.
This paper extends the cosmological bootstrap program to scale-breaking scenarios by deriving integro-differential boundary equations with memory kernels for heavy fields with time-dependent masses, enabling analytical and numerical solutions that reveal exponentially enhanced primordial features in the squeezed bispectrum.
This paper calculates and analyzes the ratio of the reduced cross-section to the proton structure function using the Block-Durand-Ha parameterization and higher twist corrections, demonstrating its consistency with HERA data and color dipole model bounds to establish its applicability for future Large Hadron Collider and Future Circular Collider projects.
This paper proposes a unified framework where a dark Higgs field drives cosmic inflation and a dark photon serves as dark matter, demonstrating that a low-reheating scenario with significant entropy dilution allows for viable WIMP and FIMP candidates consistent with cosmological observations and potentially accessible to current and future experiments.
This paper proposes that a hypothetical color-octet, electroweak-singlet scalar particle () could explain a excess in CMS 4-jet data at a dijet mass of approximately 0.95 TeV, with a complex scalar variant providing a better fit to the observed signal shape and rate than a real scalar.
This paper proposes a radiative three-loop model utilizing vectorlike leptons and asymmetric Yukawa couplings between two scalar doublets to simultaneously generate neutrino masses, provide a dark matter candidate, and remain consistent with current experimental constraints on flavor violation and mixing data.
This paper investigates how the presence of primordial black holes significantly accelerates the decay of cosmic axion string loops through enhanced energy radiation, offering a potential observational signature for axion dark matter and cosmic strings.
Using an exact Andreev soft-wall holographic model, this study reveals that relativistic rotation exceeding 16% of the speed of light induces crossover phase transitions in low-density rotating QCD matter up to a critical baryon chemical potential of approximately 363.55 MeV, beyond which first-order transitions dominate.
This paper proposes a model- and process-independent On-Shell renormalization scheme that eliminates the need for mixing matrix counterterms by utilizing a basis-free approach formulated entirely through self-energies, demonstrating its consistency by computing 1-loop hadronic -boson decay widths in the Standard Model.
