2585 papers

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 influence of the inverse Compton effect on the transverse momentum spectra of particles produced in pp collisions at \sqrt{s}=14 TeV

This study utilizes PYTHIA simulations of proton-proton collisions at 14 TeV to demonstrate that including inverse Compton scattering events in quark-gluon scattering analyses results in a moderate, constant increase in particle yield without significantly broadening transverse momentum spectra, thereby validating pp collisions as a reliable baseline for investigating energy redistribution in dense QCD media.

A new approach to long-lived particle detection at hadron colliders: the DELIGHT-SHIELD\textsf{DELIGHT-SHIELD} concept

This paper proposes the DELIGHT-SHIELD\textsf{DELIGHT-SHIELD} concept, a novel detector design for the 100 TeV Future Circular Collider that replaces inner tracking with a multi-layered composite shield to suppress Standard Model backgrounds by up to seven orders of magnitude, thereby enabling unprecedented sensitivity to long-lived particles with branching ratios as low as O(10−9)\mathcal{O}(10^{-9}).

Mass spectrum, magnetic moments and Regge trajectories of Ωccb\Omega_{ccb} and Ωcbb\Omega_{cbb} baryons in the nonrelativistic quark--diquark model

This paper employs a nonrelativistic quark-diquark model to predict the mass spectra, magnetic moments, and Regge trajectories of the triply heavy Ωccb\Omega_{ccb} and Ωcbb\Omega_{cbb} baryons, establishing a consistent link to experimental BcB_c meson data and providing reliable theoretical benchmarks for future searches at LHCb.

Three-dimensional recoil-electron reconstruction using combined optical imaging and waveform readout for electron-tracking Compton cameras

This study proposes and demonstrates a practical method for reconstructing three-dimensional recoil-electron directions in electron-tracking Compton cameras by combining high-resolution 2D optical imaging, 1D waveform readout, and deep learning, achieving improved angular and starting-point resolution without the data volume constraints of full 3D readout systems.

Search for quantum black holes in lepton+jet final states using proton-proton collisions at s=13.6\sqrt{s}=13.6 TeV with the ATLAS detector

Using 164 fb⁻¹ of proton-proton collision data at 13.6 TeV collected by the ATLAS detector during Run 3, this study reports no significant excess of quantum black hole candidates in lepton+jet final states and establishes the world's strongest exclusion limits to date, reaching a mass scale of 9.4 TeV.

Measurement of forward photon production cross-section in pp collisions at s\sqrt{s} = 510 GeV with RHICf detector

This paper reports the inclusive differential production cross-section of forward photons in proton-proton collisions at s\sqrt{s} = 510 GeV measured by the RHICf experiment, finding that the results are consistent with Feynman scaling and various hadronic interaction models despite some predicted energy dependencies.
