The reaction ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}{\ensuremath{\pi}}^{0}$ has been analyzed using 97 ${\mathrm{pb}}^{\ensuremath{-}1}$ of data taken with the Crystal Ball detector at DESY ${e}^{\ensuremath{-}}{e}^{+}$ storage ring DORIS II beam energies around 5.3 GeV. For first time we have measured cross section for $\ensuremath{\gamma}\ensuremath{\gamma}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}{\ensuremath{\pi}}^{0}$...
The T2K experiment studies oscillations of an off-axis muon neutrino beam between the J-PARC accelerator complex and Super-Kamiokande detector. Special emphasis is placed on measuring mixing angle theta_13 by observing electron appearance via sub-dominant to oscillation, searching for CP violation in lepton sector. includes a sophisticated, off-axis, near detector, ND280, situated 280 m downstream production target order measure properties understand better interactions at energy scale below...
A facility that can deliver beams of electron and muon neutrinos from the decay a stored beam has potential to unambiguously resolve issue evidence for light sterile arises in short-baseline neutrino oscillation experiments estimates effective number flavors fits cosmological data.

The `Laser-hybrid Accelerator for Radiobiological Applications', LhARA, is conceived as a novel, flexible facility dedicated to the study of radiobiology. technologies demonstrated in which have wide application, will be developed allow particle-beam therapy delivered new regimen, combining variety ion species single treatment fraction and exploiting ultra-high dose rates. LhARA hybrid accelerator system laser interactions drive creation large flux protons or light ions that are captured...

The inclusive photon spectrum in hadronic decays of the $\ensuremath{\Upsilon}(2S)$ is measured with Crystal Ball detector at DORIS II. Four well separated lines, which are consistent decay hypothesis $\ensuremath{\Upsilon}(2S)\ensuremath{\rightarrow}\ensuremath{\gamma}+^{3}P_{2,1,0}$ and $^{3}P_{2,1}\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\Upsilon}(1S)$, observed. energies lines from primary transitions...
