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 a differentiable quantum-trajectory simulation method using score-function gradient estimators to efficiently infer quark-gluon plasma transport coefficients from quarkonium suppression data by enabling gradient-based optimization on open-source Monte Carlo simulations of Lindblad dynamics.
This paper estimates and compares the discovery potential of a 100 TeV hadron collider and a 10 TeV muon collider to detect and resolve unitarity violations caused by sub-percent Higgs coupling deviations, demonstrating that both facilities can probe mass scales up to approximately 6 TeV, with intermediate precision measurements from FCC-ee providing corroborating evidence.
This paper presents the first observation and measurement of top-quark pair production in both proton-lead and lead-lead collisions using the ATLAS experiment, establishing these events as powerful probes for studying nuclear parton distribution functions and the dynamics of the quark-gluon plasma.
This paper presents a novel, compact SiPM-based detector prototype that successfully combines Ring-Imaging Cherenkov and Time-of-Flight measurements to achieve high angular and timing resolution for particle identification, demonstrating its potential for space applications where volume is limited.
This paper introduces Timepix2-Lite, a compact readout interface for the Timepix2 detector that enables nanosecond-scale timing and energy measurements, demonstrating its versatility through successful integration into diverse applications and the precise determination of the 67.5 ns half-life of the 59.5 keV transition in 237Np.
This paper utilizes QCD light-cone sum rules with high-twist and next-to-leading-order corrections to reanalyze transition form factors, confirming chiral enhancement effects and extracting optimal - mixing parameters that are strongly favored by recent BESIII experimental data.
This paper evaluates the sensitivity of future and colliders to top quark Flavor Changing Neutral Currents within Randall-Sundrum models, incorporating current and projected HL-LHC limits to determine that while the HL-LHC may reach branching ratios of , high-energy lepton colliders offer the potential to probe even smaller coupling strengths.
This paper presents measurements of identical charged-kaon femtoscopic correlations in Pb-Pb collisions at TeV, revealing that the extracted emission source radii decrease with increasing collision centrality and pair transverse momentum—a trend attributed to collective flow and well-described by hydrokinetic models, which also indicate that kaons are emitted earlier in more peripheral collisions.
This paper presents the first measurement of three-dimensional femtoscopic correlations between identical charged kaons in p$-$Pb collisions at TeV, revealing that source sizes increase with multiplicity and decrease with transverse momentum, align with trends in other collision systems, and indicate a kaon emission evolution comparable to peripheral Pb$-$Pb collisions.
This paper presents measurements of inclusive W and Z boson production cross sections and their ratios in proton-proton collisions at a center-of-mass energy of 13.6 TeV using 2022 data, yielding results that are in agreement with next-to-next-to-leading order quantum chromodynamic predictions.
