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.
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 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.
This paper introduces an eigen-microstate framework that analyzes final-state particle fluctuations in relativistic heavy-ion collisions to identify the QCD critical point by extracting dominant critical modes as a robust order parameter, offering a background-insensitive tool directly applicable to RHIC Beam Energy Scan data without relying on equilibrium assumptions.
This paper proposes and validates a method to reconstruct the local dark matter speed distribution by combining a Maxwell-Boltzmann component for old merger debris with a kinematically boosted stellar tracer for recent massive mergers, demonstrating its application to the Milky Way using Gaia data.
This paper presents a comprehensive analysis demonstrating that future electron-positron and proton-proton colliders offer an order-of-magnitude improvement in sensitivity to anomalous CP-violating interactions in the gauge-Higgs sector compared to the high-luminosity LHC, thereby providing crucial insights into new physics sources for the observed matter-antimatter asymmetry.
