We report on the measurement of γp→J/ψp cross section from E_{γ}=11.8 GeV down to threshold at 8.2 using a tagged photon beam with GlueX experiment. find that total falls toward less steeply than expected two-gluon exchange models. The differential dσ/dt has an exponential slope 1.67±0.39 GeV^{-2} 10.7 average energy. LHCb pentaquark candidates P_{c}^{+} can be produced in s channel this reaction. see no evidence for them and set model-dependent upper limits their branching fractions...
In a successful engineering run, the Heavy Photon Search Collaboration demonstrates that its upcoming heavy photon search experiment will be able to probe so far unexplored parameter regions in for dark photons.
We propose to create a secondary beam of neutral kaons in Hall D at Jefferson Lab be used with the GlueX experimental setup for strange hadron spectroscopy. The superior CEBAF electron will enable flux on order $1\times 10^4~K_L/sec$, which exceeds that previously attained SLAC by three orders magnitude. use deuteron target provide first measurements ever neutrons. experiment measure both differential cross sections and self-analyzed polarizations produced $Λ$, $Σ$, $Ξ$, $Ω$ hyperons using...
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{...

These measurements are made as function momentum transfer...
The P̄ANDA experiment at FAIR will use DIRC detectors for the separation of hadrons. compactness detector requires image planes these to be placed inside magnetic field solenoid. Due this and other boundary conditions MCP-PMTs were identified as only suitable photon sensors. Until recently major obstacle an application in high rate experiments like serious aging problems which led damage photo-cathode a fast declining quantum efficiency integrated anode charge (IAC) increased. With new...

Experiments concerning charmonium spectroscopy, search hybrids glueballs interaction hidden open charm particles with nucleons nuclei will be performed antiproton beams impinging on hydrogen or nuclear targets.

Excellent particle identification (PID) is an essential requirement for a future Electron-Ion Collider (EIC) detector. Identification of the hadrons in final state critical to study how different quark flavors contribute nucleon properties. A detector based on Detection Internally Reflected Cherenkov light (DIRC) principle, with radial size only few cm, perfect solution those requirements. The R&D process performed by EIC PID consortium (eRD14) focused designing high-performance DIRC that...
A radially-compact subsystem providing particle identification (e/π, π/K, K/p) over a wide momentum range is an essential requirement for the central detector of Electron-Ion Collider (EIC). With radial size only few cm, based on Detection Internally Reflected Cherenkov light (DIRC) principle very attractive solution. The R&D undertaken by EIC PID consortium achieved goal showing feasibility high-performance DIRC that would extend coverage well beyond state-of-the-art allowing 3σ separation...
Micro-channel plate photomultiplier tubes (MCP-PMTs) are chosen in many applications that have to cope with strong magnetic fields. The DIRC detectors of the PANDA experiment plan employ them as they show excellent timing characteristics, radiation hardness, relatively low dark count rates and sufficient lifetime. This article mainly focuses on performance position reconstruction detected photons. Two different MCP-PMTs segmented anode geometries been tested fields strengths. variation their...
