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. We strip away the dense jargon to offer both accessible plain-language explanations and detailed technical summaries, ensuring that groundbreaking research is understandable to everyone from students to seasoned experts. Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper investigates the propagation and canonical gauge structure of Generalised Non-Linear Electrodynamics in a non-dynamical background, demonstrating that a constant space-like background induces an effective photon mass and dispersive behavior while preserving two physical degrees of freedom through a deformed Abelian gauge symmetry and ensuring a positive-definite Hamiltonian.
This paper utilizes the tensor-pomeron approach, constrained by WA102 data, to predict the central exclusive production cross sections and differential distributions of and mesons in proton-proton collisions at TeV, demonstrating the feasibility of using these processes to probe the nature of the pomeron at the LHC.
This paper employs the tensor-pomeron approach to model the exclusive production of pairs in diffractive and $pp$ collisions, successfully describing H1 data for the reaction while predicting differential cross sections for $pp$ collisions at 13 TeV to guide future LHC and electron-ion collider measurements.
This paper proposes that the unusual event reported by the Lux-Zeplin collaboration, previously interpreted as evidence for WIMPs, is more likely caused by fractionally charged supermassive gravitinos, a hypothesis distinguished by large electromagnetic cross sections, low flux rates, and a predicted signature of sequential nuclear recoils within microseconds.
This paper estimates the impact of single-diffractive W and Z boson production on LHC precision measurements, finding that while these contributions induce small shifts in and the W mass, they remain below the relevant fit precision and are not expected to significantly affect phenomenological results within the tested models.
This study demonstrates that the existence and location of the holographic QCD critical point are highly sensitive to both the model's fitting procedure and the physical environment, revealing that while a critical endpoint may exist in beta-equilibrated matter, it disappears under heavy-ion collision conditions, potentially explaining the absence of clear non-monotonic fluctuation signatures in recent RHIC data.
This paper investigates exclusive diffractive electroproduction of light and heavy vector mesons within the color-dipole picture using two distinct spin-orbit light-front wave functions, finding that while the Melosh-Wigner rotation-based S-1 model better describes light-meson observables, the spin-improved S-2 form more accurately reproduces charmonium ratios and decay constants.
This paper reviews holographic QCD predictions for pseudoscalar and axial-vector meson contributions to the muon , while introducing a minimal tensor meson model that satisfies short-distance constraints and aligns well with experimental data from BELLE and BESIII.
This paper demonstrates that the gravitational capture of ultralight axions by the Sun can significantly amplify the local dark matter density at Earth, thereby enabling the derivation of tighter constraints on axion-photon coupling from current and future experiments.
This paper investigates cosmological phase transitions and stochastic gravitational-wave signals in a complex-singlet-extended Manohar-Wise model, demonstrating that both one-step and two-step thermal histories can produce observable signals from domain-wall annihilation and phase transitions within the sensitivity ranges of future space-based and pulsar-timing array detectors.
