Resumen:
Using inelastic proton-proton interactions at sqrt(s) =
900 GeV and 7 TeV, recorded by the ATLAS detector at the LHC,
measurements have been made of the correlations between forward and
backward charged-particle multiplicities and, for the first time,
between forward and backward charged-particle summed transverse
momentum. In addition, jet-like structure in the events is studied by
means of azimuthal distributions of charged particles relative to the
charged particle with highest transverse momentum in a selected
kinematic region of the event. The results are compared with predictions
from tunes of the PYTHIA and HERWIG++ Monte Carlo generators, which in
most cases are found to provide a reasonable description of the data.
