Studying atmospheric neutrino oscillations in the few-GeV range with a multimegaton detector promises to determine the neutrino mass hierarchy. This is the main science goal pursued by the future KM3NeT/ORCA water Cherenkov detector in the Mediterranean Sea. In this paper, the processes that limit the obtainable resolution in both energy and direction in charged-current neutrino events in the O...

INTRODUCTION Protons, electrons, neutrons, neutrinos and even quarks are often featured in news of scientific discoveries. All of these, and a whole "zoo" of others, are tiny sub-atomic particles too small to be seen even with the microscopes. While molecules and atoms are the basic elements of familiar substances that we can see and feel, we have to "look" within atoms in order to learn about ...

BACKGROUND Five percent of pancreatic neoplasms are non- adenocarcinoma tumors. Clinical presentation and imaging characteristics of these tumors are similar to adenocarcinoma. This study aims at evaluating the results and efficacy of Endoscopic ultrasound guided fine needle aspiration (EUS-FNA) in diagnosing the pancreatic non-adenocarcinoma tumor in patients with solid pancreatic mass. METH...

The anticipated use of more than 1000 lead fluoride ðPbF2Þ crystals as a fast and compact Cherenkov calorimeter material in a parity violation experiment at MAMI stimulated the investigation of the light yield (LY) of these crystals. The number of photoelectrons (p.e.) per MeV deposited energy has been determined with a hybrid photomultiplier tube (HPMT). In response to radioactive sources a LY...

X-ray fluorescence computed tomography (XFCT) based on sheet beam can save a huge amount of time to obtain a whole set of projections using synchrotron. However, it is clearly unpractical for most biomedical research laboratories. In this paper, polychromatic X-ray fluorescence computed tomography with sheet-beam geometry is tested by Monte Carlo simulation. First, two phantoms (A and B) filled...

The inelastic muon-nucleus interaction was studied at accelerators, in the range of large Q transfer (Q ≥ 1GeV ) mainly to measure the nucleon structure functions (deep inelastic scattering experiments). However, the bulk of interactions are characterized by low Q (Q ≤ 0.1GeV ) and can be described with the exchange of a quasi-real photon between the muon and the nucleon and they are often refe...
