Hep-Ex explores the fascinating intersection where particle physics meets experimental reality. This field investigates how scientists build massive detectors and accelerate particles to test the fundamental laws of nature, turning abstract theories into measurable data. It is the rigorous process of searching for new particles or forces that could reshape our understanding of the universe, often requiring years of collaboration and engineering.
At Gist.Science, we ensure these discoveries become accessible to everyone. We process every new preprint in this category directly from arXiv, generating both plain-language explanations for curious readers and detailed technical summaries for specialists. Our goal is to bridge the gap between complex experimental results and public understanding without losing scientific nuance.
Below are the latest papers in Hep-Ex, freshly summarized and ready for you to explore.
This paper outlines the analysis strategy and event selection methods employed by the HADES collaboration at GSI to search for Axion-Like-Particles in the decay channel using high-statistics data.
By combining DESI DR1 full-shape galaxy clustering data with CMB, BAO, and supernova observations, this study achieves percent-level cosmological constraints that significantly tighten limits on the sum of neutrino masses and provide robust evidence for the normal neutrino mass hierarchy, while also revealing a mild preference for dynamical dark energy.
This study utilizes QCD light-cone sum rules to calculate the magnetic moments of tetraquark states, demonstrating that these electromagnetic properties can effectively distinguish between different internal structures and spin-parity configurations despite similar masses.
This paper presents a sensitivity study demonstrating that the CEPC operating at a center-of-mass energy of 360 GeV, with an integrated luminosity of 1.0 ab, has the potential to discover direct stau pair production up to masses of approximately 170 GeV and smuon pair production up to 178 GeV.
This paper presents the first derivation of the two-loop renormalization-group equation for the nucleon light-cone distribution amplitude, enabling an analytic solution that reveals significant impacts on leading-logarithmic results for nucleon form factors within the hard-collinear factorization framework.
This paper presents a differentiable quantum-trajectory simulation method using score-function gradient estimators to efficiently infer quark-gluon plasma transport coefficients from quarkonium suppression data by enabling gradient-based optimization on open-source Monte Carlo simulations of Lindblad dynamics.
This paper estimates and compares the discovery potential of a 100 TeV hadron collider and a 10 TeV muon collider to detect and resolve unitarity violations caused by sub-percent Higgs coupling deviations, demonstrating that both facilities can probe mass scales up to approximately 6 TeV, with intermediate precision measurements from FCC-ee providing corroborating evidence.
This paper presents the first observation and measurement of top-quark pair production in both proton-lead and lead-lead collisions using the ATLAS experiment, establishing these events as powerful probes for studying nuclear parton distribution functions and the dynamics of the quark-gluon plasma.
This paper presents a novel, compact SiPM-based detector prototype that successfully combines Ring-Imaging Cherenkov and Time-of-Flight measurements to achieve high angular and timing resolution for particle identification, demonstrating its potential for space applications where volume is limited.
This paper introduces Timepix2-Lite, a compact readout interface for the Timepix2 detector that enables nanosecond-scale timing and energy measurements, demonstrating its versatility through successful integration into diverse applications and the precise determination of the 67.5 ns half-life of the 59.5 keV transition in 237Np.
