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.

This proceeding contribution provides an overview of extended scalar sector phenomenology, with a specific focus on light scalars at Higgs factories and a detailed examination of the discovery potential of the Inert Doublet model at lepton colliders.
The paper introduces PRBench, a rigorous benchmark comprising 30 expert-curated physics tasks for evaluating the end-to-end reproduction capabilities of AI agents, revealing that current models struggle significantly with code correctness, data accuracy, and achieving successful reproduction despite their advanced reasoning abilities.
This paper presents a comprehensive theoretical calculation of the magnetic moments for open heavy-flavor ( and ) molecular pentaquark octets within a constituent quark model, revealing distinct electromagnetic signatures that differentiate between symmetric and antisymmetric light-diquark configurations and provide crucial benchmarks for identifying these states in future experiments.
This paper demonstrates that in neutrino disappearance experiments using binned energy spectra, small mass-squared splittings become unidentifiable at quadratic order because the resulting smooth spectral distortions are absorbed by profiled nuisance parameters representing systematic uncertainties, thereby suppressing sensitivity until higher-order oscillation effects or constrained systematic models become relevant.
This paper calculates the central charged particle multiplicity distribution using a multi-channel eikonal model with AGK cutting rules, compares the results with ATLAS data at 7 and 13 TeV, and discusses the implications of color reconnection and string percolation.
This paper computes the complete one-loop contributions to the muon anomalous magnetic moment in a Doublet Left-Right Symmetric Model with inverse seesaw neutrino masses, deriving lower bounds on the masses of new gauge bosons and heavy neutrinos by imposing experimental constraints on the muon .
This paper demonstrates that small explicit Peccei-Quinn symmetry breaking can render post-inflationary QCD axion dark matter unpredictable by introducing a new mass scale that alters the axion string-wall network dynamics and relic abundance before the QCD transition.
This paper utilizes the UrQMD transport model with a coalescence afterburner to demonstrate that the production of mesons in proton-proton collisions at TeV is reasonably described by a late-stage molecular formation mechanism near kinetic freeze-out, achieving optimal agreement with ALICE data using a coalescence momentum parameter of approximately 0.365 GeV/.
Using 6.1 fb of data from the BESIII detector, this study reports the first observation of the decay with a significance of , measures its branching fraction relative to , and sets an upper limit on the intermediate process while employing a Transformer-based deep learning approach for background suppression.
This paper proposes extending the study of scattering in ultraperipheral heavy ion collisions to lower invariant masses and inelastic processes involving individual nucleons, while also calculating cross sections for associated neutron production and single photon production to guide future investigations with detectors like FOCAL and ALICE 3.
