Flavor symmetry in two body decays of bottom mesons
Dominant decays of bottom mesons into two pseudoscalars are studied in the framework of the six-quark model of the weak interactions of Kobayashi and Maskawa. Some simpleSU (3) relations between the amplitudes ar...

The Bose-Einstein correlations in deep inelastic μp interactions at 280 GeV
The Bose-Einstein correlation has been observed for pions in deep inelastic μp interactions at 280 GeV. The importance of non-interference correlations in the sample of like charge pion pairs and in the sample us...

Investigation of theW andQ 2 dependence of charged pion distributions inμ p scattering
TheW andQ 2 dependence of the fragmentation functions and of the average multiplicity of charged pions is investigated, using data from the NA9 experiment at the CERN SPS on muon-proton scattering at 280 GeV. A s...

ρ 0 andω production in deep inelastic μ-p interactions at 280 GeV/c
Inclusive distributions of ρ0 and ω mesons have been measured in deep inelastic μ-p interactions at 280 GeV/c. A comparison of the ρ0 cross sections with other leptoproduction experiments is presented. The ω resu...

One-loopN-point functions in the light-cone gauge
We consider, in the light-cone gauge, the possible structure of the counterterms arising in the solution to the renormalization equation. Using the structure of these counterterms and the noncovariant formalis...

Charge and transverse momentum correlations in deep inelastic muon-proton scattering
Correlations between charged hadrons are investigated in a 280 GeV muon-proton scattering experiment. Although most of the observed particles are decay products it is shown that the correlations found originat...

Comparison of multiplicity distributions to the negative binomial distribution in muon-proton scattering
The multiplicity distributions of charged hadrons produced in the deep inelastic muon-proton scattering at 280 GeV are analysed in various rapidity intervals, as a function of the total hadronic centre of mass...

Strangeness production in deep inelastic muon nucleon scattering at 280 GeV
The production of strange particles has been studied in a 280 GeV muon nucleon scattering experiment with acceptance and particle identification over a large kinematical range. The data show that at large valu...

Jet production and fragmentation properties in deep inelastic muon scattering
Results are presented from a study of deep inelastic 280 GeV muon-nucleon interactions on the transverse momenta and jet properties of the final state hadrons. The results are analysed in a way which attempts ...

Comparison between hadronic final states produced in μp ande + e − interactions
A comparison is made between the properties of the final state hadrons produced in 280 GeV μp interactions and ine + e − annihilation. The Lund model of hadroproduction is used as an aid in understanding the diff...

The Two-Point Correlation Function of Groups in CFA Survey
The power law form of the two-point spatial correlation function of groups of galaxies is observed among a statistically homogeneous group sample based on the CfA redshift survey. The correlation range is from...

Measurement of the longitudinal structure function and the smallx gluon density of the proton
At HERA energies the smallx region (x≲10−2) can be explored atQ 2 values large enough that leading twist QCD calculations are valid. We show how measurement of the longitudinal structure function,F ...

Charge structure of the hadronic final state in deep-inelastic muon-nucleon scattering
The general charge properties of the hadronic final state produced inμ + p andμ + d interactions at 280 GeV are investigated. Quark charge retention and local charge compensation is observed. The ratioF ...
