A detailed study of pseudorapidity densities and
multiplicity distributions of primary charged particles produced
in proton–proton collisions, at √s = 0.9, 2.36, 2.76, 7
and 8 TeV, in the pseudorapidity range |η| < 2, was carried
out using the ALICE detector. Measurements were obtained
for three event classes: inelastic, non-single diffractive and
events with at least one charged particle in the pseudorapidity
interval |η| < 1. The use of an improved track-counting algorithm
combined with ALICE’s measurements of diffractive
processes allows a higher precision compared to our previous
publications. A KNO scaling study was performed in
the pseudorapidity intervals |η| < 0.5, 1.0 and 1.5. The data
are compared to other experimental results and to models as
implemented in Monte Carlo event generators PHOJET and
recent tunes of PYTHIA6, PYTHIA8 and EPOS.

Charged-particle multiplicity distributions over a wide pseudorapidity range in proton-proton collisions at s√= 0.9, 7, and 8 TeV
ALICE Collaboration (Springer, 2017)We present the charged-particle multiplicity distributions over a wide pseudorapidity range (−3.4<η<5.0) for pp collisions at s√=0.9,7, and 8 TeV at the LHC. Results are based on information from the Silicon Pixel Detector ... -
Measurement of charm and beauty production at central rapidity versus charged-particle multiplicity in proton-proton collisions at √s = 7 TeV
ALICE Collaboration (Springer Berlin Heidelberg, 2015)Prompt D meson and non-prompt J/ψ yields are studied as a function of the multiplicity of charged particles produced in inelastic proton-proton collisions at a centreof-mass energy of √ s = 7 TeV. The results are reported ... -
Pseudorapidity and transverse-momentum distributions of charged particles in proton–proton collisions at √s = 13 TeV
ALICE Collaboration (Elsevier B.V., 2016)The pseudorapidity (η) and transverse-momentum (pT) distributions of charged particles produced in proton–proton collisions are measured at the centre-of-mass energy √s = 13 TeV. The pseudorapidity distribution in |η| < ... -
Multiplicity dependence of (multi-)strange hadron production in proton-proton collisions at √s = 13 TeV
ALICE Collaboration (Springer, 2020)The production rates and the transverse momentum distribution of strange hadrons at mid-rapidity (|y|<0.5) are measured in proton-proton collisions at s√ = 13 TeV as a function of the charged particle multiplicity, using ... -
Dielectron and heavy-quark production in inelastic and high-multiplicity proton–proton collisions at √s = 13 TeV
ALICE Collaboration (Elsevier B.V., 2019)The measurement of dielectron production is presented as a function of invariant mass and transverse momentum (pT) at midrapidity (|ye| < 0.8) in proton–proton (pp) collisions at a centre-of-mass energy of √s = 13 TeV. ...
