Query: Phenomenology of soft QCD: the role of minimum-bias measurements   This chapter summarizes minimum-bias measurements at the Large Hadron
Collider. In particular, the pseudorapidity density, the transverse-momentum
spectra, the multiplicity distribution, the correlation of average transverse
momentum and the multiplicity, and a measurement of minijets are presented. In
addition to an overview of the results obtained to date at the LHC, the
experimental challenges of defining particle and event sample and correcting to
this sample are discussed.
