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 proposes the One Scalar Theory (1ST), a predictive framework linking Higgs and top couplings to a single scale , and demonstrates that current ATLAS data and future High-Luminosity LHC runs can test this model's dynamical origin of the electroweak sector by probing up to 4 TeV through multi-Higgs and multi-top resonance searches.
This paper derives a universal expression for the leading finite-volume effects on smeared vector-vector spectral densities using two distinct approaches, demonstrating that these effects are exponentially suppressed and governed by the pion form factor, thereby providing a framework to reliably estimate and control volume extrapolations in lattice QCD calculations.
This paper establishes machine-learned particle flow (MLPF) as a foundation model for collider physics by demonstrating that its learned latent representations serve as a shared, information-rich bridge between low-level detector data and diverse high-level analysis tasks, significantly improving performance and efficiency compared to traditional modular approaches.
Using finite-temperature quantum field theory, this paper demonstrates that neutrino decays into lighter neutrinos and light bosons can be dramatically enhanced in thermal media—by up to two orders of magnitude—when parent and daughter states are nearly degenerate in mass due to strong Bose enhancement of the emitted soft bosons.
This paper investigates the mass spectrum of light hybrid baryons using a phenomenological constituent model that treats them as bound states of a color-octet three-quark core and a constituent gluon, predicting the lightest states to appear above 3 GeV with negative-parity states generally lower in energy than positive-parity ones.
This paper presents the first ab initio lattice measurements of vector resonance properties in two-flavored $Sp(4)$ gauge theory by applying generalized Lüscher's method to PNGB scattering, providing crucial data for composite Higgs models and dark matter searches while updating the theory's meson spectroscopy.
This paper introduces a significantly optimized numerical calculation for the Sartre event generator that accelerates lookup table production by 3–4 orders of magnitude while eliminating numerical instabilities, thereby enabling efficient simulation of exclusive diffractive cross sections for diverse processes at the EIC, LHeC, RHIC, and LHC.
This theoretical study proposes that the reaction offers a significantly more promising signal for detecting the predicted bound state compared to decays, urging experimental verification via upcoming LHCb upgrades to confirm the state's existence.
This paper demonstrates that recasting data from the J-PARC KOTO experiment's search for decays can establish novel limits on prompt axion-like particles in the challenging "pion chimney" mass range and extend sensitivity to a broader mass spectrum by incorporating displaced decays.
This paper presents updated observational constraints on the spatially flat CDM dynamical dark energy model using Planck 2018 and non-CMB data, finding that while the standard CDM model remains an excellent fit, current data mildly favor evolving quintessence-like dark energy and reveal tensions in the Hubble constant and CMB lensing amplitude that are partially alleviated by allowing the lensing consistency parameter to vary.
