This paper presents a minimal basis for non-derivative baryon-number-violating operators in the Standard Model Effective Field Theory up to mass dimension 11, as well as specific dimension-12 operators, offering a set of terms that generally features fewer components and simpler contractions than existing results while acknowledging cases where minimality conflicts with structural simplicity.
Using a (3+1)-dimensional viscous hydrodynamic model with IP-Glasma initial conditions, this study demonstrates that accurately accounting for prompt photon contributions resolves the long-standing discrepancy between theoretical predictions and experimental measurements of direct photon anisotropic flow in Au+Au collisions at GeV.
This paper establishes a connection between leading singularities and canonical bases for Feynman integrals beyond polylogarithms by demonstrating that selecting integrals with unit leading singularities necessitates introducing new transcendental functions related to geometric periods, which satisfy -factorized differential equations and correspond to a specific decomposition of the period matrix.
This paper proposes a "dip-hunting" strategy using parametric neural networks to identify top-philic scalar resonances through destructive interference patterns, addressing the limitations of traditional bump-hunting methods in regions where interference invalidates the narrow-width approximation.
This paper derives model-independent microlensing constraints on the density and mass of fast and slow compact objects with non-standard velocities, demonstrating how their distinct kinematic properties open new parameter spaces and significantly alter observational limits compared to conventional dark matter searches.
This study employs an effective Lagrangian approach combined with QCD sum rules to demonstrate that increasing baryonic density induces a negative mass shift in the meson due to $DD$ and meson loop contributions, suggesting the formation of meson-nucleus bound states and providing binding energy and decay width predictions for various nuclei to guide upcoming experimental investigations.
This work demonstrates that for the production of inclusive jets at the LHC, the usual scale variations used to estimate missing higher-order uncertainties can be drastically unreliable, as NNLO+NNLL calculations reveal that resummation effects significantly alter both the central cross sections and the uncertainty estimates.
This article proposes a framework to solve the inverse problem of identifying the ultraviolet origins of CP violation and Peccei-Quinn symmetry breaking by demonstrating that six representative classes of effective operators near the QCD scale generate distinct, experimentally distinguishable patterns of electric dipole moments across various nuclear, atomic, and molecular systems.
This paper presents a unified analysis of experimental and lattice QCD data that confirms the and as SU(3) flavor partner resonance states with specific pole masses and widths, while revealing that their internal structure requires significant components beyond simple meson-meson molecules.
This paper utilizes chiral effective field theory and experimental data to calculate hadronic form factors and predict branching ratios, invariant-mass distributions, and forward-backward asymmetries for semileptonic decays into axion-like particles and mesons, thereby providing a quantitative foundation for future experimental searches.
