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 reviews the confusion surrounding radiative decays of hadronic molecules in existing literature, clarifies the distinctions between different decay types, and emphasizes the critical importance of accounting for the system's scale hierarchy to properly interpret these decays.
Researchers have synthesized a one-dimensional metallic polymeric nitrogen phase at high pressure and temperature that exhibits predicted superconductivity and exceptional energy density, positioning it as a promising candidate for both electronic and energetic applications.
This paper presents a two-stage convolutional neural network that efficiently reconstructs the six-dimensional beam phase space at a cathode surface from just sixteen transverse screen images, offering a faster and less computationally demanding alternative to conventional tomography techniques for particle accelerator diagnostics.
This paper presents updated inclusive cross sections for electroweak Higgs boson pair production at LHC-relevant energies, calculated at NLO QCD+NLO EW for vector-boson fusion and NNLO QCD for associate production, covering both Standard Model predictions and scenarios with anomalous trilinear Higgs self-couplings.
This paper demonstrates that combining atmospheric neutrino data with the ESSnuSB super-beam program significantly enhances the precision of measuring the leptonic CP phase and resolves neutrino mass ordering degeneracies.
This paper presents the first leading-order Standard Model calculation of triply polarized $WWW$ production at the LHC, revealing that the triply-transverse polarization fraction dominates at approximately 51% while the triply-longitudinal fraction remains negligible at 1.4%, thereby highlighting the significant experimental challenge of measuring the latter.
This paper discusses various internal criteria and influencing factors for assessing the quality of data unfolding results in particle physics and related fields, addressing the challenge of evaluating deconvolution accuracy when external benchmarks are unavailable.
Using 54.4 fb of 13 TeV proton-proton collision data from the CMS experiment, a search for narrow resonances decaying to diphotons in the 10–70 GeV mass range found no significant excess over the expected background, leading to the setting of upper limits on production cross sections and an interpretation within an axion-like particle framework.
This paper presents new radioassay results from the Canfranc Underground Laboratory demonstrating that dedicated development has significantly reduced the radiopurity levels of Micromegas readout planes, confirming their suitability for ultra-low background rare event searches.
Using collision data from the BESIII detector, this study measures the branching fraction and form factor parameters for the decay , while setting the first upper limit on the previously unobserved decay.
