This study investigates the structural effects of , , and mesons on Be nuclei using HAL QCD potentials and the Gaussian expansion method, revealing that the meson strongly binds the system into stable states while and interactions are weaker and form only shallow bound states, with specific predictions for new -charmonium bound states and the non-Borromean nature of .
This paper investigates the monotonic increase of proton partonic entropy under DGLAP evolution, demonstrating that saturation effects at small x are essential to tame this growth and proposing entanglement entropy as a testable observable within simplified saturation models.
This paper investigates how the chameleon mechanism in scalar-tensor theories causes superradiant scalar clouds around Kerr black holes to exhibit unique growth and stimulated decay patterns in non-uniform matter distributions, generating distinct electromagnetic signals that can differentiate fundamental scalars from other light bosonic fields.
The paper introduces EveNet, a foundation model pretrained on 500 million simulated collision events that leverages a hybrid learning objective to outperform state-of-the-art methods in diverse high-energy physics tasks, demonstrate exceptional data efficiency, and successfully validate its transferability to real experimental data for precision physics and discovery.
This paper investigates the pair production of charged scalars () within the scotogenic model, demonstrating that the process is dominated by -channel exchange of singlet right-handed fermions (including the dark matter candidate) and providing predictions for future high-energy colliders to test the model's parameter space.
This paper analyzes the transition form factors using newly derived light-cone distribution amplitudes within the light-cone sum rule framework, demonstrating that intrinsic charm and gluonic components significantly influence the observables, particularly stabilizing the channel while enhancing the sensitivity of the channel at high .
This paper presents a detailed calculation of the 2-loop self-energy for a scalar particle using a simple sector decomposition method to efficiently separate ultraviolet divergences from finite parts, enabling both analytic and numerical renormalization.
This paper proposes that exclusive heavy (axial-)vector meson production in lepton-proton collisions at the Electron-Ion Collider can serve as a unique experimental probe for the elusive gluon generalized transverse momentum-dependent distributions and by analyzing specific azimuthal-angle-dependent observables arising from virtual-photon polarization interference.
Using dispersion relations and accounting for chiral symmetry breaking-induced field mixing, this study calculates the attractive -wave scattering lengths for and systems, revealing that their interactions are predominantly governed by soft-gluon exchange rather than coupled-channel mechanisms.
This paper presents the first lattice QCD calculation of the irreducible Standard Model background for the decay, determining the branching fraction for to be to provide a critical benchmark for dark matter searches.
