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.
The paper proposes Vision Calorimeter (ViC), a novel framework that adapts visual object detectors with a physics-inspired heat-conduction operator to significantly improve the accuracy of anti-neutron position and momentum estimation in high-energy physics.
The paper proposes MORRIS, a novel tabletop experiment using a magnetically levitated sub-millimeter particle in a superconducting trap to search for non-Newtonian gravity via a Yukawa-like fifth force, with projected sensitivities that surpass existing bounds for screening lengths around 1 mm.
This paper proposes a supersymmetry model with R-parity violation to explain two rare 8 TeV four-jet events observed by the CMS Collaboration as a heavy down-squark decaying into two lighter first-generation right-handed squarks, while outlining the constraints and predictions for future LHC verification.
The paper introduces TIGER, a novel topology-agnostic hierarchical graph network that overcomes the limitations of single-topology models by leveraging the universal structure of sequential two-body decays to perform flexible, multi-task event reconstruction and classification for diverse physics processes at the LHC.
This paper presents a slim, quantized, and parameter-reduced version of the L-GATr jet tagger that achieves an order-of-magnitude reduction in energy cost with only a moderate performance decrease, paving the way for efficient trigger-level jet tagging at the LHC.
Using 138 fb of proton-proton collision data at 13 TeV collected by the CMS detector, this study searches for heavy resonances decaying into two Higgs bosons in the final state, finding no evidence of new physics and setting the most sensitive limits to date on such production for resonance masses between 1.4 and 4.5 TeV.
The CMS experiment measured the differential production cross sections of the (1S), (2S), and (3S) mesons in proton-proton collisions at = 13.6 TeV using 37.4 fb of 2022 data, analyzing their decay into muon pairs across specific transverse momentum and rapidity intervals.
This study utilizes the Hadron Resonance Gas model in Partial Chemical Equilibrium to analyze Au+Au collisions at RHIC energies, revealing that baryon annihilation ceases between chemical and kinetic freeze-out and demonstrating that inelastic hadronic interactions significantly shape the final hadron composition.
This paper presents an overview of tau lepton physics, highlighting the significance of the super tau-charm factory's energy region through the lens of the tau's discovery and precision measurements, while identifying open issues and future research opportunities.
Using 5.4 fb of Run 2 data collected by the LHCb experiment at 13 TeV, a search for the lepton-flavour-violating decay found no evidence of the process and set an upper limit of on its branching fraction at the 90% confidence level.
