This paper presents new analytical all-order results for small- resummation, most notably the first properly resummed $qg$ splitting kernel, which form the basis of a more robust and numerically stable implementation in the upcoming HELL 4.0 framework.
This paper investigates how primordial non-Gaussianity can convert small-scale Poisson fluctuations of evaporating primordial black holes into large-scale isocurvature perturbations in the dark sector, thereby establishing new constraints on dark matter production scenarios alongside re-evaluations of limits from overproduction, warm dark matter, and scalar-induced gravitational waves.
This paper employs an open quantum systems framework to demonstrate that an ultralight scalar field coupled to neutrinos induces decoherence in neutrino oscillations with a damping parameter scaling as , differing from the dependence typically assumed in phenomenological models.
This paper analyzes radiative corrections in no-scale supergravity inflation models, demonstrating that while such corrections can destabilize predictions in certain Wess-Zumino scenarios, specific classes like the Cecotti model maintain small loop effects that preserve agreement with Planck CMB data.
This paper analyzes elastic $pp$ and scattering within the Color Glass Condensate framework using experimental data to derive phenomenological upper bounds on the odderon amplitude, finding that while current parametrizations can describe the data, large uncertainties limit the precision of these constraints and highlight the need for improved measurements.
This paper proposes a framework for testing quantum gravity by analyzing the stochastic gravitational-wave background from evaporating near-Planck-mass primordial black holes, demonstrating that their unthermalized graviton spectra preserve distinct signatures of modified temperature-mass relations that can be used to discriminate between various beyond-semiclassical theories.
This study investigates the state using flux-tube and quark pair creation models, concluding that its anomalous decay pattern cannot be explained by a conventional scenario but instead provides strong evidence for -hybrid mixing in the strange sector, offering guidance for future experimental searches at BESIII, LHCb, and Belle-II.
This paper investigates the Sommerfeld enhancement in dark matter annihilation into unstable, non-relativistic final-state particles by incorporating their decay widths into the Schrödinger equation, revealing that narrow-width bound states induce resonant enhancements that significantly impact dark matter relic abundance predictions.
This paper investigates how the Weinberg angle, a fundamental parameter in the Standard Model that may vary with environmental conditions, influences the Fermi coupling constant and consequently determines the initial neutron abundance in Big-Bang nucleosynthesis and the neutron lifetime.
This paper presents updated inclusive cross sections for electroweak Higgs boson pair production at LHC-relevant energies, calculated at NLO QCD+NLO EW for vector-boson fusion and NNLO QCD for associate production, covering both Standard Model predictions and scenarios with anomalous trilinear Higgs self-couplings.
