An accelerator beam experiment was performed using a low-energy antiproton beam to measure the antiproton detection efficiency of the BESS detector. Measured and calculated efficiencies derived from the BESS Monte Carlo simulation based on geant/gheisha showed good agreement. With the detailed verification of the BESS simulation, results demonstrate that the relative systematic error of detecti...

We performed feasibility studies for various single transverse spin measurements that are related to the Sivers effect, transversity and tensor charge, Collins fragmentation function. The processes studied include semi-inclusive deep inelastic scattering (SIDIS) where hadrons (pions kaons) were detected in addition scattered DIS lepton. data obtained {\sc pythia}6 geant}4 simulated e+p collisio...

Les auteurs rapportent chez deux nourrissons, l'etude anatomo-clinique d'un cas de kystes alveolaires multiples,et d'un cas d'emphyseme lobaire congenital bilateral.Le troisieme cas concerne un kyste bronchog6nique du poumon gauche,decouvert a l'autopsie d'un nouveau-ne. Dans le quatrieme cas,un emphyseme geant du lobe superieur gauche,decouvert dans un contexte infectieux,a l'age de neuf mois,...

In the course of its operation, the Volcano Ranch array collected data on the lateral distribution of showers produced by cosmic rays at energies above 10 eV. From these data very precise measurements of the steepness of the lateral distribution function, characterized by the η parameter, were made. The current availability of sophisticated hadronic interaction models has prompted a reinterpret...

We have developed a detailed Monte Carlo simulation program for the Belle TOF system. Based on GEANT simulation, it takes account of all physics processes in the TOF scintillation counters and readout electronics. The simulation reproduces very well the performance of the Belle TOF system, including the dE/dx response, the time walk effect, the time resolution, and the hit efficiency due to bea...

High Energy Physics (HEP) needs a huge amount of computing resources. In addition data acquisition, transfer, and analysis require a well developed infrastructure too. In order to prove new physics disciplines it is required to higher the luminosity of the accelerator facilities, which produce more-andmore data in the experimental detectors. Both testing new theories and detector R&D are based ...

Cloud Platform as a Service (PaaS) provides an environment for creating and deploying applications using one of popular development platforms. This paper presents a practical solution for building a service composition platform based on the GEMBus (GEANT Multi-domain Bus) that extends the industry accepted Enterprise Service Bus (ESB) platform with automated services composition functionality a...

Radio Cherenkov radiation is arguably the most efficient mechanism for detecting showers from ultra-high energy particles of 1 PeV and above. Showers occuring in Antarctic ice should be detectable at distances up to 1 km. We report on electromagnetic shower development in ice using a GEANT Monte Carlo simulation. We have studied energy deposition by shower particles and determined shower parame...
