Description:
Charged-particle distributions sensitive to the properties of the underlying event are measured for an
- inclusive sample of events containing a $Z$-boson, decaying to an electron or muon pair. The measurement
- is based on data collected using the ATLAS detector at the LHC in proton–proton collisions at a
- centre-of-mass energy of 7 TeV with an integrated luminosity of 4.6~$\text{fb}^{−1}$. Distributions of
+ inclusive sample of events ontaining a $Z$-boson, decaying to an electron or muon pair. The measurement
+ is based on data collected using the ATLAS detector at the LHC in proton--proton collisions at a
+ centre-of-mass energy of 7 TeV with an integrated luminosity of 4.6 fb$^{-1}$. Distributions of
the charged particle multiplicity and of the charged particle transverse momentum are measured in regions
of azimuthal angle defined with respect to the $Z$-boson direction.
