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 minimalistic model containing four scalar multiplets to simultaneously explain multiple excesses observed at the LHC (notably at 95 GeV and 650 GeV), arguing that these hints disfavor common scalar extensions while predicting specific charged scalars that make the theory testable and falsifiable despite current data limitations.
Using 138 fb of proton-proton collision data at 13 TeV collected by the CMS experiment, this study presents a search for new resonances decaying into a Higgs boson and an anomalous jet identified via an autoencoder, finding no significant excess over Standard Model background and setting the most stringent upper limits to date on the production cross sections for various benchmark scenarios.
This study employs a refined AMPT transport model with adjusted beauty quark mass and flavor-specific coalescence parameters to successfully reproduce LHCb and ALICE data on beauty and non-prompt charm hadron production in 13 TeV $pp$ collisions, offering new insights into heavy quark dynamics and hadronization mechanisms in small collision systems.
This paper presents state-of-the-art predictions for muon-electron scattering at the MUonE experiment by performing the first all-order resummation of soft and soft-collinear logarithms, matched with higher-order corrections to significantly reduce perturbative uncertainties and accurately describe the signal region.
This paper outlines NOvA's current search strategy for eV-scale sterile neutrinos using NuMI beam data and details future plans to incorporate Booster Neutrino Beam data to enhance sensitivity in the systematics-limited high parameter space favored by experimental anomalies.
This paper presents the first complete next-to-next-to-next-to-leading order QCD calculation of heavy-to-light semi-leptonic decay structure functions, enabling precision predictions for triple differential rates that are crucial for determining CKM matrix elements and resolving tensions in measurements.
This paper demonstrates that the glass scintillator SG101 is a promising candidate for high-efficiency thermal neutron detection and precise event tagging, exhibiting superior pulse shape discrimination performance and significant physical correlations when coupled with organic scintillators like EJ200 and EJ276.
The authors report the first successful demonstration of an annular AlMn Transition-Edge Sensor (TES) for X-ray detection, achieving a record-breaking energy resolution of 12.1 eV at 17.48 keV (below 0.1%), thereby validating AlMn alloys as a promising alternative to traditional bilayer TESs for high-resolution X-ray spectrometry.
This paper presents the first complete perturbative QCD corrections to heavy-to-light structure functions using a hybrid computational strategy, providing state-of-the-art predictions for semi-leptonic -meson decays and revealing novel boundary-effect terms essential for consistent mass-scheme reformulations at third order.
This paper presents a feasibility study demonstrating the use of Generative Adversarial Networks (GANs) to generate synthetic signal samples for rare heavy-flavour hadrons like the in ALICE Pb-Pb collisions, offering a computationally efficient alternative to traditional full simulations for enhancing reconstruction sensitivity.
