The Electron-Ion Collider (EIC), a state-of-the-art facility for studying the strong force, is expected to begin commissioning its first experiments in 2028. This an opportune time artificial intelligence (AI) be included from start at this and all phases that lead up experiments. second annual workshop organized by AI4EIC working group, which recently took place, centered on exploring current prospective application areas of AI EIC. not only beneficial EIC, but also provides valuable...
We report on the results of first search for production axion-like particles (ALPs) via Primakoff nuclear targets, γA→aA, in "SRC-CT" experiment using GlueX detector at Jefferson Lab. This uses an integrated luminosity 100 pb⋅−1nucleon a 12C target with real photon beam energies 6<Eγ<10.8 GeV, and explores mass region 200<ma<450 MeV decay a→γγ. range is between π0 η meson masses, which enables use measured rate to obtain absolute bounds ALP reduced sensitivity experimental detection...
We present a search for axionlike particles, $a$, produced in photon-proton collisions at center-of-mass energy of approximately 4 GeV, focusing on the scenario where $a$-gluon coupling is dominant. The uses $a\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$ and $a\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$ decays, data sample corresponding to an integrated luminosity $168\text{ }\text{...
We report on the measurement of beam asymmetry $\mathrm{\ensuremath{\Sigma}}$ for reactions $\stackrel{P\vec}{\ensuremath{\gamma}}p\ensuremath{\rightarrow}p\ensuremath{\eta}$ and $\stackrel{P\vec}{\ensuremath{\gamma}}p\ensuremath{\rightarrow}p{\ensuremath{\eta}}^{\ensuremath{'}}$ from GlueX experiment using an 8.2--8.8-GeV linearly polarized tagged photon incident a liquid hydrogen target in Hall D at Jefferson Laboratory. These measurements are made as function momentum transfer...
We present a search for possible spin dependent interactions of the neutron with matter through exchange 1 bosons axial vector couplings as envisioned in extensions Standard Model. This was sought using slow polarimeter that passed transversely polarized neutrons by unpolarized slabs material arranged so this interaction would tilt plane polarization and develop component along momentum. The result rotation angle, $ϕ'_{V_5} = [2.8\pm\,4.6(stat.)\pm\,4.0(sys.)]\times 10^{-5}~\mbox{rad/m}$ is...
We report on the measurement of spin density matrix elements $\mathrm{\ensuremath{\Lambda}}(1520)$ in photoproduction reaction $\ensuremath{\gamma}p\ensuremath{\rightarrow}\mathrm{\ensuremath{\Lambda}}(1520){K}^{+}$, via its subsequent decay to ${K}^{\ensuremath{-}}p$. The was performed as part GlueX experimental program Hall D at Jefferson Laboratory using a linearly polarized photon beam with...
We report a measurement of the π− photoproduction beam asymmetry for reaction →γp→π−Δ++ using data from GlueX experiment in photon energy range 8.2–8.8 GeV. The Σ is measured as function four-momentum transfer t to Δ++ and compared phenomenological models. find that varies t: negative at smaller values positive higher |t|. can be described theoretically by t-channel particle exchange requiring pseudoscalar, vector, tensor intermediaries. In particular, this requires charge exchange, allowing...
We report measurements of the photon beam asymmetry $\mathrm{\ensuremath{\Sigma}}$ for reaction $\stackrel{P\vec}{\ensuremath{\gamma}}p\ensuremath{\rightarrow}{K}^{+}{\mathrm{\ensuremath{\Sigma}}}^{0}$(1193) using GlueX spectrometer in Hall D at Jefferson Lab. Data were collected by a linearly polarized energy range 8.2--8.8 GeV incident on liquid hydrogen target.

We report on the first measurement of $J/\psi$ photoproduction from nuclei in photon energy range $7$ to $10.8$ GeV, extending above and below threshold free proton $\sim8.2$ GeV.

The neutron spin rotation (NSR) collaboration used parity-violating of transversely polarized neutrons transmitted through a 0.5 m liquid helium target to constrain weak coupling constants between nucleons. While consistent with theoretical expectation, the upper limit set by this measurement on angle is limited statistical uncertainties. NSR preparing new improve statistically-limited result about an order magnitude. In addition using high-flux NG-C beam at NIST Center for Neutron Research,...
Polarized slow neutrons can be used to conduct sensitive searches for subtle spin-dependent neutron interactions in matter. A brief overview of the theoretical context which such are important is given. We present result a recent measurement spin rotation liquid helium that constrains possible exotic long-range parity-odd between and matter from exchange 1 bosons meV-scale masses. The experiment also places first upper bound our knowledge on what may called “in-matter”gravitational torsion....
