A study of fluctuations and correlations in deep-inelastic muon-nucleon scattering at 280 GeV

Using data of the European Muon Collaboration on muon-proton and muon-deuteron scattering at 280 GeV, an intermittency analysis in one, two and three phase space dimensions is carried out. In addition, a factorial correlator analysis and a multifractal analysis, both in one dimension (rapidity), are presented.     

The effect of pressure on the hydration shell of ions

The effect of pressure on the structure of a 2.2 molal NaCl solution around room temperature was investigated by analyzing the results of molecular dynamics simulations at pressures of 1 bar and 10 kbar. The increase in pressure results in a slight decrease in the hydration shell structures of sodium and chloride ions. On the other hand, the H-bond structure of the solvent water undergoes a significant distortion is similar to that found in pure water.     

Investigation of intermittency in muon-proton scattering at 280 GeV

In this paper intermittency is investigated in hadron production by muon proton interactions at 280 GeV, using data of the European Muon Collaboration. Intermittent behaviour is observed in the dependence of the scaled factorial moments on the rapidity bin width. This behaviour is stronger for positive than for all charged hadrons; it increases with the hadronic cms energyW, and is larger in the central region than in the fragmentation regions. The data are compared with the predictions of the Webber model, the Lund model, and of short-range ordering     

Two-particle correlations and the origin of intermittency in muon-nucleon interactions

The relation between two-particle correlations, in particular the Bose-Einstein effect, and the intermittency signal is investigated in muon-nucleon scattering at 280 GeV using data of the European Muon Collaboration. From a comparison of the second factorial moments for unlike and negative charges with each other and with the predictions of the Lund model it is concluded that the observed intermittent behaviour is due to Bose-Einstein interference.
