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 presents the design and simulation of a dispersion suppressor channel for a wedge-based final cooling scheme in a 10 TeV Muon Collider, aiming to achieve the necessary transverse emittance reduction of 22 μm while avoiding the technical challenges associated with 40 T solenoids by reducing dispersion to approximately 0.001 m.
This paper investigates non-logarithmic heavy-quark mass effects in the two-jet limit of the Energy-Energy Correlation by introducing a novel partial event fraction calculable via real emission diagrams in four dimensions and proposing an improved factorization scheme that ensures a smooth massless limit through an angle-dependent coefficient function.
This paper demonstrates that damped heavy neutrino-antineutrino oscillations significantly alleviate the suppression of lepton number violation in symmetry-protected pseudo-Dirac heavy neutral leptons at hadron colliders, while showing that combining lepton-number-blind and lepton-number-violating searches can distinguish these models from the double-Majorana limit despite the sensitivity challenges posed by small mass splittings.
This paper presents the first complete numerical solution to the BDMPS-Z equations for in-medium QCD splittings, providing a precise determination of splitting functions that goes beyond standard soft, large-, and harmonic-oscillator approximations by incorporating finite-energy effects, subleading-color contributions, and realistic parton-medium interactions.
Experiments on the Kunwu laser facility and particle-in-cell simulations reveal that broadband laser pulses enhance two-plasmon decay and hot electron generation primarily through stochastic intensity spikes, suggesting that mitigating these spikes is key to controlling hot electron production in direct-drive scenarios.
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.
