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 proposes a universal quantum measurement protocol that extracts the velocity and direction of light dark matter wind from the phase differences between quantum sensors, offering superior sensitivity compared to classical correlation methods without compromising detector performance.
Using 138 fb⁻¹ of 13 TeV proton-proton collision data collected by the CMS detector, this paper presents a model-independent measurement of the differential production cross section for Higgs bosons decaying to W boson pairs in association with two jets, utilizing a machine learning-derived variable to constrain Higgs couplings within the Standard Model effective field theory framework.
Using LHCb proton-proton collision data from 2016 to 2018, this paper reports a precise measurement of the branching fraction relative to and determines the isospin asymmetry between and decays.
This paper proposes a protocol for enhancing dark matter detection sensitivity by projecting quantum sensors into a collective excited state, which suppresses non-collective noise by a factor equal to the number of sensors without requiring the maintenance of entanglement during signal accumulation.
The GlueX experiment at Jefferson Lab reports the first observations of and photoproduction alongside production, revealing forward-peaked angular distributions consistent with Regge-like -channel exchanges and a phenomenological double-exchange model, while finding no narrow resonant structures and observing a suppression of pairs similar to other reactions.
This paper proposes a hybrid nuclear-electronic spin sensor utilizing hyperfine interactions in silicon donors to overcome the low-frequency sensitivity limits of conventional nuclear magnetic resonance, thereby enabling compact solid-state detection of galactic axions with projected sensitivity exceeding direct nuclear methods by an order of magnitude.
This paper presents the design and experimental characterization of the POKERINO prototype, a PbWO-based electromagnetic calorimeter utilizing SiPM sensors, to validate its performance and energy resolution capabilities for the NA64 experiment's search for light dark matter.
This study demonstrates that an X-ray free-electron laser Compton collider operating at GeV could probe the Higgs self-coupling with a precision of 7% to 12% in the channel by employing boosted decision trees and genetic algorithm optimization, establishing it as a powerful complementary tool to future and hadron colliders for investigating electroweak symmetry breaking.
This paper utilizes an quiver gauge theory to classify and predict four distinct scenarios of additional TeV-scale particles that could be discovered during the Run 4 of the upgraded LHC, which is scheduled to begin in 2030.
Using 13 TeV proton-proton collision data from 2017, the ATLAS collaboration conducted a model-independent search for invisible particles produced in photon-photon interactions by reconstructing the missing mass via forward proton tagging, finding no significant excess over Standard Model predictions and setting upper limits on fiducial cross sections for various signal models.
