This paper proposes a bipartite solution to the primordial lithium problem involving two sequential late decays—a majoron into neutrinos that reduces lithium but overproduces deuterium, followed by an axion-like particle into photons that photodissociates the excess deuterium while further depleting lithium—demonstrating a viable mechanism to resolve the lithium discrepancy without violating current deuterium constraints.
This paper proposes a model-independent method for directly measuring the production fractions of and mesons at the resonance by counting single- and double-inclusive charmed mesons, demonstrating that world-average precision can be achieved without relying on underlying theoretical assumptions.
This paper proposes that dark particles with lepton-flavor-violating couplings to the tau lepton can trigger decay cascades resulting in rare, high-multiplicity neutrinoless tau decays (such as or ) that dominate over traditional three-body signatures and offer new experimental search channels across various dark sector models.
This paper presents an analytical computation of angular phase-space integrals with three and four denominators using dimensional regularisation and the Mellin-Barnes representation, expressing the results in terms of Goncharov polylogarithms and deriving recursion relations to facilitate the solution of full phase-space integrals.
This paper presents a comprehensive simulation of primordial black hole (PBH) cluster evolution using the Smoluchowski coagulation equation and Monte Carlo methods to model merger dynamics with and without mass segregation, thereby determining runaway timescales and mass population evolution to explain high-redshift supermassive black holes observed by JWST.
This paper derives a positive-signature Pomeron amplitude with specific scaling properties that successfully describes the dip-bump region of $pp$ elastic scattering differential cross-sections at LHC energies through an analytic continuation of -channel partial waves featuring poles at fractional values on the real axis.
This paper proposes a Template-Adapted Mixture Model that leverages multiple biased simulations to perform robust, data-driven parameter inference for signal fraction estimation, effectively mitigating simulation-data mismodeling in complex particle physics analyses.
This paper presents a study using fully simulated events in the ILD detector at the ILC Higgs factory to investigate the sensitivity of future high-energy colliders to dark photons () decaying into muon pairs, highlighting their potential to probe mixing parameters and masses beyond the reach of current experiments like Belle II.
This paper proposes a lepton seesaw model utilizing modular symmetry to unify the mass origins of charged leptons and neutrinos through distinct seesaw mechanisms, demonstrating that viable solutions with successful predictions emerge near the fixed point favored by Type IIB string theory flux compactification.
Using the highest-energy neutrino event detected by KM3NeT, this paper derives stringent constraints on Dark Matter-neutrino interactions that effectively rule out simplified dark sector models with masses above the MeV scale, suggesting that richer dark sector structures are required to produce meaningful constraints.
