This paper presents the first leading-order Standard Model calculation of triply polarized $WWW$ production at the LHC, revealing that the triply-transverse polarization fraction dominates at approximately 51% while the triply-longitudinal fraction remains negligible at 1.4%, thereby highlighting the significant experimental challenge of measuring the latter.
This paper proposes a new methodology for directly detecting heavy cosmic dark matter by utilizing intense high-energy photon or muon beams at particle facilities, demonstrating that such experiments could observe significant scattering rates, particularly at a proposed muon collider Higgs factory.
This study demonstrates that the charge-weak form factor difference in Ca and Zr is highly sensitive to the isovector spin-orbit interaction due to specific shell structures, whereas Pb and Ni remain insensitive, thereby guiding a strategic approach to use parity-violating electron scattering on these distinct nuclei to separately constrain the isovector spin-orbit strength and the symmetry energy slope.
This paper presents a numerical evaluation of the two-loop QCD squared matrix elements for and processes involving heavy quark axial couplings, demonstrating a novel method that handles all singularities and complications directly in four spacetime dimensions without dimensional regularization.
This paper derives exact, convergent representations for multiloop sunset Feynman integrals in two dimensions with arbitrary masses and all loop orders, utilizing symmetric polynomials and dimension-raising relations to facilitate high-precision numerical evaluation and the systematic reconstruction of four-dimensional results.
This article reviews non-perturbative unitarization methods, such as the Inverse Amplitude Method and dispersive frameworks like Roy equations, which are essential for extending Effective Field Theories beyond their perturbative limits by preserving fundamental S-matrix principles and dynamically generating resonances in hadronic and electroweak sectors.
While decaying dark matter can mimic the background effects of massive neutrinos and allow for eV-scale masses when only distance-based data are used, the inclusion of CMB perturbation observables, particularly lensing, decisively breaks this degeneracy and restores tight neutrino mass constraints.
This paper extends the theoretical and phenomenological analysis of recent NA61/SHINE collaboration findings by establishing the conceptual and analytical foundations of isospin symmetry and proving that, under charge-symmetry invariant initial conditions, the mean multiplicities of charged and neutral kaons should be equal, thereby highlighting the significance of the observed violation.
This paper presents a theoretical framework for elastic neutrino-nucleon scattering that incorporates electromagnetic interactions of massive Dirac neutrinos through matrix-defined form factors and a spin-flavor density matrix to analyze the effects of charge radii, magnetic moments, and spin polarization in experimental contexts.
This paper extends the concept of hadronic covalent bonds induced by shared quarks to explain exotic hadrons like and by establishing a logical framework where molecular existence depends on wave function overlap and Pauli principle satisfaction, while incorporating both the creation and annihilation of sea quark-antiquark pairs as unique strong interaction mechanisms for studying QCD confinement.
