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 highlights how the high-precision measurements of electron and muon magnetic moments serve as critical tests of the Standard Model and quantum field theory, with the electron offering the most stringent validation of current theories and the muon providing a sensitive probe for discovering new physics beyond the Standard Model.
This paper demonstrates that transformer-based deep learning architectures significantly outperform traditional cut-based analyses in detecting top quark flavor-changing neutral current interactions with photons at the LHC, enabling the exploration of rare branching ratios as low as at the high-luminosity phase.
This paper presents methodologies and tools for deploying Transformer-based subatomic particle tracking models onto FPGAs, addressing current tool limitations and resource constraints through monolithic or automated partitioned synthesis to achieve low-latency inference.
Using the Born-Oppenheimer approximation within a dynamical diquark model, this study identifies the states as compact tetraquarks composed of axial-vector diquark pairs, supported by calculated root-mean-square radii significantly smaller than 1 fm.
This paper presents state-of-the-art theoretical predictions for the electromagnetic Dirac form factors of hyperons by computing next-to-leading-order QCD corrections within the hard-collinear factorization framework and combining them with lattice QCD-determined distribution amplitudes.
This paper presents a new real-time luminosity determination method for the upgraded LHCb experiment, implemented directly in the VELO detector's FPGA firmware using 40 MHz hit reconstruction, which achieves sub-percent statistical resolution and millisecond-level granularity during the 2024 physics run.
Using CMS data from PbPb collisions at 5.02 TeV, this study measures the azimuthal anisotropy of prompt D mesons and finds their flow coefficients to be consistent with those of D mesons, indicating that the strangeness content does not significantly alter the mesons' interaction with the quark-gluon plasma within the measured transverse momentum range.
Using the CLAS12 detector at Jefferson Lab, researchers reported the first measurement of beam spin asymmetries for dihadrons in semi-inclusive deep inelastic scattering, employing a machine learning-based photon classifier to significantly enhance statistics and revealing a nonzero asymmetry sensitive to the twist-3 quark-gluon correlation PDF as well as the first experimental evidence for the isospin dependence of the helicity-dependent dihadron fragmentation function .
Using 136 fb of 13 TeV proton-proton collision data from the CMS detector, this study simultaneously measures the signal and searches for the process, finding the former consistent with Standard Model predictions while setting an observed upper limit on the charm quark Yukawa coupling modifier at 3.0 times its SM value.
This paper details the completion and engineering challenges of excavating the 69-meter diameter by 94-meter high underground cavern for the Hyper-Kamiokande detector, highlighting the design evolution and construction methods employed to realize this massive rock cavern 600 meters underground.
