### Track-based minimum bias at 900 GeV and 2.36 and 7 TeV in ATLAS (ATLAS_2010_S8918562)

Spires | arXiv:1012.5104

Measurements from proton-proton collisions at centre-of-mass energies of sqrt(s) = 0.9, 2.36, and 7 TeV recorded with the ATLAS detector at the LHC. Events were collected using a single-arm minimum-bias trigger. The charged-particle multiplicity, its dependence on transverse momentum and pseudorapidity and the relationship between the mean transverse momentum and charged-particle multiplicity are measured. Measurements in different regions of phase-space are shown, providing diffraction-reduced measurements as well as more inclusive ones. The observed distributions are corrected to well-defined phase-space regions, using model-independent corrections.

### Track-based underlying event at 900 GeV and 7 TeV in ATLAS (ATLAS_2010_S8894728)

Spires | arXiv:1012.0791

The underlying event measurements with the ATLAS detector at the LHC at the center of mass energies of 900 GeV and 7 TeV. The observables sensitive to the underlying event, i.e the charged particle density and charged pT sum, as well as their standard deviations and the average pT, are measured as functions of the leading track. A track pT cut of 500 MeV is applied for most observables, but the main profile plots are also shown for a lower track cut of 100 MeV, which includes much more of the soft cross-section. The angular distribution of the charged tracks with respect to the leading track is also studied, as are the correlation between mean transverse momentum and charged particle multiplicity, and the `plateau' height as a function of the leading track $|\eta|$.

### Charged particles at 900 GeV in ATLAS (ATLAS_2010_S8591806)

Spires | arXiv:1003.3124

The first measurements with the ATLAS detector at the LHC. Data were collected using a minimum-bias trigger in December 2009 during proton-proton collisions at a centre of mass energy of 900 GeV. The charged- particle density, its dependence on transverse momentum and pseudorapid- ity, and the relationship between transverse momentum and charged-particle multiplicity are measured for events with at least one charged particle in the kinematic range $|\eta| < 2.5$ and $p_\perp > 500$ MeV. All data is corrected to the particle level.

### Pseudorapidities at three energies, charged multiplicity at 7 TeV. (ALICE_2010_S8625980)

Spires | Eur.Phys.J. C68 (2010) 345-354 | arXiv:1004.3514 [hep-ex]

This is an ALICE publication with pseudorapities for $\unit{0.9, 2.36 and 7}{\TeV}$ and the charged multiplicity at $\unit{7}{\TeV}$. The analysis requires at least on charged particle in the event. Only the INEL distributions are considered here
