This paper proposes that the Standard Model's internal symmetries arise from the nested algebraic embeddings of real numbers through complex numbers, quaternions, and octonions into a 16-dimensional algebra, where specific conditions on endomorphisms and graded structures naturally yield the known gauge groups and charge operators.
The paper introduces Dffusion, a permutation-equivariant diffusion model that serves as a fast and accurate surrogate for computationally expensive Monte Carlo simulations of incoherent pair creation backgrounds at high-luminosity colliders like FCC-ee, generating events nearly four orders of magnitude faster than Geant4 while faithfully reproducing key kinematic and detector-level distributions.
This review article explores the origins of photons in ultra-peripheral collisions of heavy ions and protons, highlighting their diverse applications in studying nuclear structure at low Bjorken-, probing beyond-standard-model physics, and investigating new quantum mechanical regimes through interferometry.
Using the quark delocalization color screening model, this study predicts three bound states and two resonance states in the molecular systems, with the bound state identified as a particularly promising candidate for future experimental verification.
This paper extends a 3-3-1 model with singlet leptoquarks, which successfully explains the muon anomalous magnetic moment and , to demonstrate that lepton-flavor-violating Higgs and boson decays exhibit a linear correlation with radiative decays and reveal a complementary interplay between electron and muon anomalous magnetic moments that allows specific decay channels to reach experimental limits while suppressing others.
This study demonstrates that nonlinear collective flow in ultra-central U+U collisions, particularly through the sixth-order harmonic's sensitivity to mode coupling, provides a direct and experimentally accessible signature to isolate the intrinsic hexadecapole deformation () and reveal deviations from the quadrupole--hexadecapole scaling in nuclear structure.
This paper investigates the confinement phase transition in pure Yang-Mills theory at finite using the Improved Holographic QCD model, demonstrating that the critical temperature decreases with to reduce supercooling and analyzing the resulting dynamical formation of domain walls and their potential gravitational wave signatures.
This paper proposes a type-I seesaw framework utilizing non-holomorphic modular symmetry to naturally generate quasi-degenerate right-handed neutrinos for resonant leptogenesis at the TeV scale, while simultaneously predicting a distinctive double-peaked gravitational wave spectrum from domain wall annihilation and a first-order phase transition.
This paper introduces an automated framework within the Sherpa event generator for simulating photon-induced processes in proton and nuclear collisions with full impact-parameter dependence and higher-order electroweak corrections, which is validated against ATLAS data and used to provide new predictions for exclusive - and -pair production.
This paper examines the uniqueness of analytically continuing Euclidean Green functions, derived from Dyson-Schwinger equations and constrained by lattice data, back to physical Minkowski space for applications in the decay model.
