The Belle detector at the KEKB electron-positron collider has collected almost 1 billion Y(4S) events in its decade of operation. Super-KEKB, an upgrade is under construction, to increase luminosity by two orders magnitude during a three-year shutdown, with ultimate goal 8E35 /cm^2 /s luminosity. To exploit increased luminosity, been proposed. A new international collaboration Belle-II, being formed. Technical Design Report presents physics motivation, basic methods accelerator upgrade, as...

A fully compensating uranium—scintillator calorimeter was constructed for the ZEUS detector at HERA. Several of barrel modules were subjected to beam tests Fermilab before shipping them DESY installation. The calibrations used beams electrons and hadrons, measuring uniformity response, checking resolution. runs also provided opportunity test a large fraction actual readout system in an integrated environment more than one year HERA turn on. experiment utilized two computer controlled...

In e+e- annihilation product functions is measured. We report nonzero asymmetries for pairs charge-ordered pi+pi- pairs, which indicate significant in this channel. results are obtained from 672 fb-1 data sample that contains 711 \times 106 and was collected at near ?(4S) resonance, Belle detector KEKB asymmetric-energy collider.
The Askaryan Radio Array (ARA) is an ultra-high energy (UHE, $>10^{17}$ eV) neutrino detector designed to observe neutrinos by searching for the radio waves emitted relativistic products of neutrino-nucleon interactions in Antarctic ice. In this paper, we present constraints on diffuse flux between $10^{16}-10^{21}$ eV resulting from a search two complementary analyses, both analyzing four years data (2013-2016) deep stations (A2, A3) operating at that time. We place 90 % CL upper limit all...
