hep-ex papers | Gist.Science

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.

Flavor, transverse momentum, and azimuthal dependence of charged pion multiplicities in SIDIS with 10.6 GeV electrons

This paper reports high-precision measurements of charged pion multiplicities and their azimuthal modulations in semi-inclusive deep inelastic scattering off proton and deuteron targets using a 10.6 GeV electron beam at Jefferson Lab, revealing consistent transverse momentum dependencies and significant $\pi^-$ azimuthal asymmetries that will enable improved determinations of quark transverse momentum distributions.

Reviving $Z^\prime$ Portal Dark Matter with Conversion Mechanism

This paper proposes a gauged $U(1)_{B-L}$ benchmark model featuring a compressed dark fermion spectrum and a small mixing angle to suppress direct detection constraints, demonstrating that a novel conversion mechanism effectively generates the observed dark matter relic density while remaining consistent with current collider and cosmological limits.

ALP and $Z^\prime$ boson at the Electron-Ion collider

This paper investigates the sensitivity of the upcoming Electron-Ion Collider to purely electrophilic axion-like particles and $Z^\prime$ bosons in the GeV mass range, demonstrating that the facility can significantly extend exclusion limits on these new physics scenarios through tri-electron and photon final state analyses.

Search for a boosted Higgs boson decaying to bottom quark pairs in association with a W or Z boson in proton-proton collisions at $\sqrt{s}$ = 13 TeV

Using 138 fb $^{-1}$ of proton-proton collision data at 13 TeV collected by the CMS detector, a search for boosted Higgs bosons decaying to bottom quark pairs in association with hadronically decaying W or Z bosons yielded an observed signal strength of $\mu$ = 0.72 $^{+0.75}_{-0.71}$ , consistent with the Standard Model expectation within uncertainties.

On the simulated kinematic distributions of heavy meson decays

This paper identifies unphysical kinematic features in EvtGen simulations of semileptonic $B$ decays involving resonances caused by neglected phase-space factors and proposes a reweighting method to correct the affected hadronic invariant mass distributions.
