To study fundamental questions of hadron and nuclear physics in interactions antiprotons with nucleons nuclei, the universal PANDA detector will be built. Gluonic excitations, strange charm quarks nucleon structure studies performed unprecedented accuracy thereby allowing high-precision tests strong interaction. The proposed is a state-of-the art internal target at HESR FAIR detection identification neutral charged particles generated within relevant angular energy range. This report...
A detection system of the conventional PET tomograph is set-up to record data from e+ e- annihilation into two photons with energy 511 keV, and it gives information on density distribution a radiopharmaceutical in body object. In this paper we explore possibility performing three gamma imaging based ortho-positronium annihilation, as well positronium mean lifetime J-PET constructed plastic scintillators. For purposes simulations formation its were performed taking account distributions...
The Jagiellonian Positron Emission Tomograph (J-PET) is the first PET built from plastic scintillators.J-PET prototype consists of 192 detection modules arranged axially in three layers forming a cylindrical diagnostic chamber with inner diameter 85 cm and axial field-of-view 50 cm.An arrangement long strips scintillators, their small light attenuation, superior timing properties, relative ease increase opens promising perspectives for cost effective construction whole-body scanner, as well...
Positronium created in a human body during PET scans hallmarks neoplastic tissues.
Positronium is the simplest bound state, built of an electron and a positron. Studies positronium in vacuum its decays medium tell us about Quantum Electrodynamics, QED, structure matter biological processes living organisms at nanoscale, respectively. Spectroscopic measurements constrain our understanding QED state theory. Searches for rare effect gravitation on are used to look new physics phenomena. In materials sensitive inter- intra-molecular metabolism ranging from single cells human...
We report on an exclusive and kinematically complete high-statistics measurement of the basic double-pionic fusion reaction pn→dπ(0)π(0) over full energy region ABC effect, a pronounced low-mass enhancement in ππ-invariant mass spectrum. The measurements, which cover also transition to conventional t-channel ΔΔ process, were performed with upgraded WASA detector setup at COSY. data reveal Abashian-Booth-Crowe effect be uniquely correlated Lorentzian dependence integral cross section....

The existence of a light dark force mediator has been tested with the KLOE detector at DAPHNE. This particle, called U, is searched for using decay chain phi-->etaU, eta-->pi+pi-pi0, U-->e+e-. No evidence found in 1.5 fb-1 data. resulting exclusion plot covers mass range 5
The novel whole-body PET system based on plastic scintillators is developed by the {J-PET} Collaboration. It consists of scintillator strips arranged axially in form a cylinder, allowing cost-effective construction total-body PET. In order to determine properties scanner prototype and optimize its geometry, advanced computer simulations using GATE software were performed. spatial resolution, sensitivity, scatter fraction noise equivalent count rate estimated according NEMA norm as function...
The existence of a new force beyond the Standard Model is compelling because it could explain several striking astrophysical observations which fail standard interpretations. We searched for light vector mediator this dark force, $\mathrm{U}$ boson, with KLOE detector at DA$\Phi$NE $\mathrm{e}^{+}\mathrm{e}^{-}$ collider. Using an integrated luminosity 1.54 fb$^{-1}$, we studied process $\mathrm{e}^{+}\mathrm{e}^{-} \to \mathrm{U}\gamma$, $\mathrm{U} \mathrm{e}^{+}\mathrm{e}^{-}$, using...

The recent interest in a light gauge boson the framework of an extra U(1) symmetry motivates searches mass range below 1 GeV. We present search for such particle, dark photon, e+e−→Uγ, U→π+π− based on 28 million e+e−→π+π−γ events collected at DAΦNE by KLOE experiment. π+ π− production initial-state radiation compensates loss sensitivity previous U→e+e−, μ+μ− due to small branching ratios ρ–ω resonance region. found no evidence signal and set limit 90% CL mixing strength between photon ε2, U...
Charged lepton system symmetry under combined charge, parity, and time-reversal transformation (CPT) remains scarcely tested. Despite stringent quantum-electrodynamic limits, discrepancies in predictions for the electron-positron bound state (positronium atom) motivate further investigation, including fundamental tests. While CPT noninvariance effects could be manifested non-vanishing angular correlations between final-state photons spin of annihilating positronium, measurements were...
