This review provides a pedagogical overview of the strong CP problem, detailing the standard Peccei-Quinn solution involving the QCD axion while also summarizing recent developments in alternative theoretical approaches and their phenomenological status.
This paper investigates the inclusive lifetimes of and baryons using the homogeneous bag model and nonrelativistic quark model, demonstrating that spin-zero and spin-one diquark mixing significantly reduces the lifetimes of neutral states and that the lifetime extrema occur at mixed angles rather than in pure spin configurations.
This paper derives the stability conditions for static, spherically symmetric black holes with scalar hair in general quartic-quintic GLPV theories, revealing that while generic non-degenerate branches are locally unstable or degenerate, specific Horndeski-compatible deformations of scalar-Gauss-Bonnet black holes can satisfy all no-ghost and gradient-stability requirements.
This paper reformulates the type-I seesaw mechanism as a relativistic fermionic proximity effect to derive exact nonlocal self-energies, establish rigorous positivity constraints and matrix inequalities between lepton-number-conserving and violating spectral moments, and provide a framework for reconstructing sterile-sector parameters from effective field theory data.
This paper investigates the implications of the Plan B Model for neutrino physics, demonstrating that combining a Froggatt-Nielsen mechanism with a clockwork suppression allows the model to successfully fit current neutrino oscillation data using order-unity fundamental couplings while simultaneously addressing anomalies and quark mixing hierarchies.
This paper presents a next-to-leading order calculation of radiative pion-pair production () using the disperon QED method to incorporate experimental data via the pion vector form factor, with results implemented in the McMule Monte Carlo framework to assess theoretical uncertainties across various experimental scenarios.
This paper investigates the predicted electric dipole moments of various particles within the Generational Three-Higgs-Doublet Model, demonstrating that while scalar contributions generally cancel weakly for the quark, neutron, and mercury atom, they exhibit significant cancellation for the quark and electron, leading to distinct phenomenological predictions under current experimental constraints.
Using the Gaussian expansion and complex scaling methods with interactions derived from lattice QCD, this study predicts that the baryon induces deeply bound, contracted states in due to strong attraction, whereas the baryon yields only weakly bound or resonant states in , highlighting their distinct "gluelike" behaviors in exotic hypernuclei.
This paper presents the first next-to-next-to-leading-logarithmic accuracy fit of the unpolarised gluon transverse-momentum-dependent distribution to LHCb -pair production data, introducing novel methodologies to incorporate perturbative and PDF uncertainties that are crucial for accurately describing low-scale gluon-sensitive measurements.
This paper presents updated Standard-Model predictions for the inclusive radiative decay by incorporating new NLO multi-parton contributions and NNLO interference calculations that eliminate a long-standing charm-mass uncertainty, resulting in a branching ratio of that aligns well with current experimental data.
