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 introduces Parnassus, a public, GPU-enabled Python/PyTorch framework that offers fast, interchangeable detector simulation and reconstruction models for various particle physics experiments, providing a ROOT-free alternative to traditional tools like Geant4 and Delphes.
This white paper summarizes the landscape of new physics opportunities beyond neutrino oscillations at current and future accelerator, atmospheric, and reactor neutrino facilities, with a particular focus on East Asian programs and next-generation sensitivities as presented at the NPN 2024 workshop.
This paper investigates how synchrotron radiation emitted by the witness bunch in the magnetic chicanes of a staged, beam-driven plasma wakefield accelerator impacts the machine's accelerating gradient and ultimate energy potential.
This paper investigates how track functions, which encode the flow of energy from partons to charged hadrons, are modified by the quark-gluon plasma in heavy-ion collisions, demonstrating that their non-linear evolution and higher moments can discriminate between different jet quenching models and provide a direct test of quantum field theory predictions within the medium.
This paper employs multi-current QCD light-cone sum rules to derive distinct analytic electromagnetic signatures, specifically a light-quark magnetic moment ratio of and a vanishing charm contribution for specific currents, which serve as falsifiable tests to distinguish compact pentaquark structures from hadronic molecules.
This study utilizes the Zubarev non-equilibrium statistical operator approach to demonstrate that introducing an effective pion chemical potential successfully explains the low- enhancement in identified particle spectra from LHC heavy-ion collisions, offering a viable alternative to conventional resonance decay explanations.
This paper presents a resonant search for ultralight dark matter using a quantum-limited cavity optomechanical accelerometer that achieved a sensitivity of but detected no signal, thereby validating the platform as a scalable approach for future competitive constraints on vector-mediated dark-matter interactions.
This paper investigates a portal vector-like lepton extension of the Standard Model, demonstrating that a multi-TeV muon collider can significantly enhance the associated production of the Higgs boson with a dark photon () compared to the standard channel, thereby offering a promising avenue to probe dark matter phenomenology, constrain dark photon parameters, and address the muon anomaly.
This paper investigates the "look everywhere" effect in machine learning-based anomaly detection, demonstrating that while training and testing on the same data leads to miscalibrated -values, strategies like k-folding offer an effective balance between statistical calibration and sensitivity to new physics.
This paper demonstrates that in the Two-Higgs-Doublet Model with a heavy scalar , the branching ratios for resonant di-Higgs () and tri-Higgs () production are directly correlated with the decay rate solely by the scalar mass, predicting a fixed ratio of approximately 9.4 between and for masses between 500 GeV and 1 TeV, thereby establishing as the primary probe for heavy scalar resonances at current and future colliders.
