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 paper demonstrates that within a general weak effective theory framework, the angular distributions of semileptonic decays exhibit distinctive modifications due to massive invisible fermions, enabling the identification of observables sensitive to the particle's mass and the discrimination between left- and right-handed lepton-dark-sector currents.
This paper establishes that a four-dimensional non-linear electrodynamics theory is equivalent to Maxwell theory in a field-dependent, unit-determinant curved spacetime if and only if it possesses electric-magnetic duality invariance, a property that uniquely characterizes ModMax theory and enables a novel analysis of global symmetries and conserved currents via harmonic forms with respect to the induced metric.
This paper proposes that ultra-high-energy cosmic ray clustering at tens of EeV is best explained by light nuclei originating from nearby galaxies and AGN within the Local Sheet, while offering alternative mechanisms involving neutrino interactions or heavy nuclei deflections for the highest-energy events.
This study utilizes the Zubarev non-equilibrium statistical operator approach to demonstrate that introducing an effective pion chemical potential successfully explains the low- enhancement in identified particle spectra from LHC heavy-ion collisions, offering a viable alternative to conventional resonance decay explanations.
This paper derives and numerically explores a momentum-dependent Beth-Uhlenbeck equation for Gaussian fluctuations in a generalized 2+1D Gross-Neveu model, revealing significant deviations from previous Lorentz-boosted approximations, including the resurrection of pseudoscalar bound states and substantial contributions from Landau modes to fluctuation pressure.
This paper proposes a novel Mixture-of-Experts Graph Transformer model that achieves high predictive accuracy in distinguishing rare Supersymmetric signals from Standard Model backgrounds in ATLAS collision data while embedding interpretability through attention maps and expert specialization to align AI-driven decisions with physics-informed features.
This paper reviews how the cosmological QCD phase transition in an inhomogeneous early Universe could simultaneously drive the formation of primordial black holes as dark matter candidates and enable the local synthesis of heavy r-process elements through the gravitational stabilization and evaporation of quark-gluon plasma droplets.
This paper summarizes the EMMI Rapid Reaction Task Force's findings on how recent experimental and theoretical advances challenge conventional macroscopic descriptions by demonstrating that collective, hydrodynamic-like behavior can emerge in mesoscopic quantum systems with few particles, thereby probing the limits of effective theories across size, equilibrium, and interaction frontiers.
This paper demonstrates that future electron-positron colliders can achieve a discovery of a 150 GeV charged scalar predicted by the Real Higgs Triplet model with less than 1 fb of integrated luminosity and measure its mass with GeV-level precision by analyzing specific multi-jet and multi-lepton signal regions.
Using the latest DESI DR2, Planck, ACT, and SH0ES data, this study demonstrates that an interacting dark energy model derived from asymptotic-safety quantum gravitational field theory significantly improves the cosmological fit and alleviates the tension to a level by favoring a negative dynamical scale parameter for the cosmological constant.
