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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
By employing a expansion in holographic models of confining gauge theories, the authors demonstrate that the maximum supercooling in thermal confinement transitions is universally suppressed by and determined by the speed of sound in the deconfined phase, independent of specific scalar potential details.
This paper presents the release notes for CONTUR version 3, detailing its enhanced capabilities for constraining new physics theories using RIVET's extensive library of LHC measurements through improvements in statistical treatments, efficiency, plotting utilities, and the inclusion of new data and Standard Model predictions.
The paper argues that collider experiments cannot provide unconditional proofs of entanglement or test locality via Bell's inequalities because the measurement of commuting final-state momenta allows for the construction of a local hidden variable theory that reproduces the observed data while satisfying Bell's inequality.
This paper discusses how extending the Standard Model's scalar sector with new spin-zero fields can address unresolved issues like dark matter and matter-antimatter asymmetry, necessitating experimental verification through collider and dark matter detection facilities.
This paper presents a systematic analysis of wave-packet sizes in quantum mechanical scatterings, emphasizing that their magnitudes are not universal constants but depend on environmental coherence lengths and experimental conditions, which in turn determine the absolute probabilities of state transitions.
This paper presents a novel Padé-based algorithm that reinterprets Froissart doublets as diagnostic tools to iteratively identify and remove data inconsistencies, thereby enabling the reliable reconstruction of a function's analytic structure from finite datasets without requiring a specific model for the errors.
This paper presents a Bayesian spectral inference framework for Taiji-like missions that integrates second-generation time-domain simulations with frequency-domain likelihoods to accurately model full-covariance effects in unequal-arm, time-evolving configurations, demonstrating consistent parameter estimation for stochastic gravitational-wave backgrounds and phase-transition signals.
Using lattice theory as a proof of principle, this paper demonstrates that classical field simulations can effectively model particle production and subsequent equilibration in nonequilibrium quantum field dynamics, establishing a scalable pathway for future quantum computing applications in studying pre-equilibrium systems like the early Universe and heavy-ion collisions.
This paper constructs effective field theories for spontaneous lepton number breaking within Type I, II, and III Seesaw mechanisms coupled to a complex scalar, demonstrating that the resulting Majoron models are falsifiable through specific correlations between observables—such as the invisible Higgs width, non-unitarity in the leptonic mixing matrix, and a TeV-scale lepton-number breaking scale—rather than the absolute magnitude of individual couplings.
This paper demonstrates that flat-space on-shell amplitudes can exactly determine the channel-basis mixing projectors for electromagnetic and gravitational perturbations of a Reissner-Nordström black hole, while also revealing that these alignments are spoiled by finite-mass recoil effects and require spin-induced angular-mode mixing in rotating generalizations.
