Four different combinations of 4496Ru and 4096Zr nuclei, both as projectile target, were investigated at the same bombarding energy 400AMeV using a 4π detector. The degree isospin mixing between target nucleons is mapped across large portion phase space two isospin-tracer observables, number measured protons tritium to 3He yield ratio. experimental results show that global equilibrium not reached even in most central collisions. Quantitative measures stopping are extracted from data. They...
We present an analysis of charm quark fragmentation at 10.6 GeV, based on a data sample $103\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected by the Belle detector KEKB accelerator. consider into main charmed hadron ground states, namely ${D}^{0},{D}^{+},{D}_{s}^{+}$ and ${\ensuremath{\Lambda}}_{c}^{+}$, as well excited states ${D}^{*0}$ ${D}^{*+}$. The functions are important to measure they describe processes low energy scale, where calculations in perturbation theory lead large...
We report measurements of the photon beam asymmetry $\Sigma$ for reactions $\vec{\gamma}p\to p\pi^0$ and p\eta $ from GlueX experiment using a 9 GeV linearly-polarized, tagged incident on liquid hydrogen target in Jefferson Lab's Hall D. The asymmetries, measured as function proton momentum transfer, possess greater precision than previous $\pi^0$ are first $\eta$ this energy regime. results compared with theoretical predictions based $t$-channel, quasi-particle exchange constrain...
The GlueX experiment at Jefferson Lab ran with its first commissioning beam in late 2014 and the spring of 2015. Data were collected on both plastic liquid hydrogen targets, much detector has been commissioned. All systems are now performing or near design specifications events being fully reconstructed, including exclusive production π0, η ω mesons. Linearly-polarized photons successfully produced through coherent bremsstrahlung polarization transfer to ρ observed.

A new electromagnetic calorimeter (ECAL) consisting of 1596 lead tungstate PbWO 4 scintillating crystals has been fabricated and installed in the experimental Hall D at Jefferson Lab (JLab). The highgranularity, high-resolution is required by JLab Eta Factory experiment, whose main physics goal to study rare decays eta mesons. ECAL replaced inner part forward glass GlueX detector. Signals from detector will be digitized using twelve-bit flash analog-to-digital converters operated a sampling...
We have measured the branching fraction B, longitudinal polarization fL, and CP asymmetry coefficients A S for B0→ρ+ρ− decays with Belle detector at KEKB e+e− collider using 253 fb−1 of data. obtain B=[22.8±3.8(stat)+2.3−2.6(syst)]×10−6, fL=0.941+0.034−0.040(stat)±0.030(syst), A=0.00±0.30(stat)±0.09(syst), S=0.08±0.41(stat)±0.09(syst). These values are used to constrain Cabibbo-Kobayashi-Maskawa phase ϕ2; solution consistent standard model is ϕ2=(88±17)° or 59°<ϕ2<115° 90% C.L.Received 11...
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.

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...
