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.

JetFormer: A Scalable and Efficient Transformer for Jet Tagging from Offline Analysis to FPGA Triggers

JetFormer is a scalable, encoder-only Transformer architecture designed for particle jet tagging that achieves high accuracy and computational efficiency across both high-precision offline analysis and ultra-low-latency FPGA-based online triggers.

Assessing the Impact of Fitting Methodology at aN3^3LO with FPPDF: an Open Source Tool for Extracting Parton Distribution Functions in the Hessian Approach

The paper introduces FPPDF, a new open-source tool that implements the MSHT collaboration's polynomial parameterization and Hessian error approach using NNPDF's theoretical and experimental libraries, ultimately demonstrating that the impact of moving to aN3^3LO perturbative orders is largely independent of the chosen PDF parameterization methodology.

Can Dirac neutrinos destabilize Z2\mathcal{Z}_2 domain wall network?

This paper demonstrates that if a Z2\mathcal{Z}_2 symmetry responsible for generating light Dirac neutrino masses is spontaneously broken, it can radiatively induce the explicit breaking necessary to destabilize domain wall networks, thereby creating a predictable link between the Dirac neutrino mass scale and a detectable stochastic gravitational wave signal.
