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 presents the physics program and detector design of the Spin Physics Detector (SPD) project at the NICA collider, which aims to investigate the spin structure of protons and deuterons, particularly gluon distributions, through high-luminosity collisions of polarized beams.
This paper presents new results from the ATLAS detector at the LHC regarding searches for vector-like quarks and leptoquarks, which are hypothesized particles in extensions of the Standard Model designed to address the hierarchy problem and flavor anomalies.
This paper proposes a unified KSVZ-type axion model incorporating modular symmetry and a global symmetry to simultaneously explain the origin of radiative Dirac neutrino masses, the strong CP problem, and dark matter, while predicting a massless neutrino and testable signatures for charged lepton flavor violation and axion-photon coupling.
This paper employs a nonperturbative Hamiltonian framework using Daubechies wavelets in momentum space to analyze dimensional theory, successfully demonstrating the emergence of a strong-coupling phase transition in the sector.
This paper proposes a refined search strategy targeting a narrow axion mass window of 78.6 to 79.6 micro-eV (18.99–19.01 GHz) using a resonant cavity detection scheme based on the inverse Primakoff effect, supported by recent simulations and novel experimental designs involving Josephson Parametric Amplifiers and Resonant Tunneling Diodes.
This paper presents the threshold resummation of large logarithms up to NNLL accuracy for on-shell -boson pair production at the LHC, demonstrating that matching these resummed predictions to NNLO fixed-order results significantly reduces scale uncertainties and provides a precise description of the invariant mass distribution in the high-energy regime.
This paper investigates the significant CP violation induced by forward-backward asymmetry in the decay within the phase space dominated by and resonances, predicting asymmetries of up to 35% that are potentially observable by Belle and Belle-II collaborations.
This paper demonstrates that Affleck-Dine baryogenesis can be realized with low-energy, non-supersymmetric physics involving a light scalar field, which produces detectable gravitational waves in the LIGO frequency range, thereby establishing a new complementarity between gravitational wave astronomy and particle physics experiments.
This paper presents NNLO+NNLL threshold resummation results for on-shell -boson pair production at the LHC, demonstrating that the resummation enhances the cross-section by approximately 6.3% at high invariant masses while significantly reducing scale uncertainties from 6.8% to 4.1%.
This paper proposes that ultralight dark matter can be detected at colliders not as a standard isolated resonance, but as a "smeared" oscillating resonance caused by a mediator whose mass varies over time, offering a unique discovery channel that complements existing constraints from atomic clocks.
