Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.
At Gist.Science, we process every new preprint in this category as soon as it appears on arXiv.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper argues that the right-handed neutrino field in the Type I seesaw model is not a Majorana fermion, thereby precluding neutrinoless double beta decay, and proposes that both leptogenesis and neutrinoless double beta decay can be realized by redefining the model with C-symmetric Majorana fermions via a Bogoliubov transformation.
This paper investigates the resonance within the conventional quark-antiquark picture by constructing its light-cone distribution amplitudes, calculating transition form factors using QCD light-cone sum rules with corrections, and predicting the differential decay widths and branching fractions for the four-body semileptonic decay .
This paper proposes and demonstrates through Monte Carlo simulations that collider experiments, specifically using -lepton pair production at electron colliders, can test phase-space non-separability and quantify momentum entanglement by realizing EPR-like correlations in coordinates and momenta rather than spins.
This paper reinterprets ATLAS and CMS monojet and mono- search results at 13 TeV to set upper limits on excited neutrino production, excluding masses up to approximately 4 TeV in benchmark scenarios and providing complementary constraints on low-mass, high-coupling regions.
This paper employs multi-current QCD light-cone sum rules to derive distinct analytic electromagnetic signatures, specifically a light-quark magnetic moment ratio of and a vanishing charm contribution for specific currents, which serve as falsifiable tests to distinguish compact pentaquark structures from hadronic molecules.
This paper proposes and validates a computationally efficient method for tracing parameter variations in Sherpa's multi-parton interaction and colour reconnection models through event-by-event reweighting, enabling robust uncertainty quantification and tuning using LHC and Tevatron data.
This paper calculates the radiative decay width of the to transition within the chiral unitary approach by treating both states as dynamically generated -wave hadronic molecules, finding a central width of 6.7 keV that is sensitive to form factors and residue phases, and proposes specific observables to test their molecular nature.
This paper reports a localized excess at in the dilepton-photon invariant mass spectrum using CMS data, providing additional support for a narrow scalar resonance hypothesis and extracting a radiative decay ratio compatible with beyond-Standard-Model scenarios.
This paper proposes a process-independent spin-tomography framework for pairs that reconstructs the full two-spin density matrix from weak-decay angles, demonstrating that scalar spin correlations alone are insufficient to verify quantum entanglement and predicting specific tensor anisotropy signatures in $pp$ and collisions that can be tested with current experiments like STAR and Belle II.
This paper reinterprets the convergence region of Schwarzschild quasinormal mode expansions by introducing a radial mirror scattering framework that maps the problem to a two-component half-line system, thereby providing a spectral explanation for the second lightcone distance and drawing a parallel to AdS boundary-bouncing geodesics.
