2610 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.

Production correlation of light (hyper-)nuclei in Au-Au collisions from the RHIC Beam Energy Scan

This paper employs a quark combination model within a hadronic coalescence framework to systematically analyze the production of light nuclei and hypernuclei in Au-Au collisions across the RHIC Beam Energy Scan, successfully explaining existing experimental data for species like deuterons and hypertritons while predicting yields for various Ω\Omega-hypernuclei and exploring their production correlations as a function of collision energy.

Record accumulation of antiprotons in a Penning-Malmberg Trap and their preparation for improved production of antihydrogen beams

This paper reports the commissioning of a new Penning-Malmberg trap at CERN's GBAR experiment that achieves a record accumulation of over 6.4×1076.4 \times 10^7 antiprotons in under 35 minutes and delivers 6.4×1066.4 \times 10^6 antiprotons per shot with reduced emittance, significantly enhancing the production rate of antihydrogen beams for gravitational studies.

Jet quenching and its substructure dependence due to color decoherence

Motivated by color coherence and decoherence effects, this paper proposes a theoretical framework combining vacuum-like evolution and medium-induced radiation to successfully describe the inclusive jet modification factor and its substructure dependence in 0–10% PbPb collisions at sNN=5.02 TeV\sqrt{s_{NN}} = 5.02~\rm{TeV} as measured by ATLAS.

Search for Higgs boson production at high transverse momentum in the WW decay channel in proton-proton collisions at s\sqrt{s} = 13 TeV

Using 138 fb−1^{-1} of proton-proton collision data at 13 TeV collected by the CMS experiment, this study presents the first dedicated search for highly Lorentz-boosted Higgs bosons decaying to WW pairs, finding no evidence of a signal above background with a measured signal strength of μ\mu = $-$0.19−0.46+0.48^{+0.48}_{-0.46}.

Revisiting Type-II see-saw: Present Limits and Future Prospects at LHC

This paper conducts a comprehensive study of the Type-II see-saw mechanism with a non-degenerate triplet Higgs spectrum, deriving updated 95% CL lower limits on the doubly charged scalar mass that exceed current LHC constraints by 50–230 GeV while identifying unconstrained parameter regions and proposing improved search strategies for the high-luminosity phase.
