### CDF Run 1 charged multiplicity measurement (CDF_2002_S4796047)

Spires | Phys.Rev.D65:072005,2002 | doi:10.1103/PhysRevD.65.072005

A study of $p\bar{p}$ collisions at sqrt(s) = 1800 and 630 GeV collected using a minimum bias trigger in which the data set is divided into two classes corresponding to soft' and hard' interactions. For each subsample, the analysis includes measurements of the multiplicity, transverse momentum (pT) spectra, and the average pT and event-by-event pT dispersion as a function of multiplicity. A comparison of results shows distinct differences in the behavior of the two samples as a function of the center of mass energy. The properties of the soft sample are invariant as a function of c.m. energy. It should be noticed that minimum bias tunings of PYTHIA made by ATLAS in early 2010, which used this among all other available data from CDF and from ATLAS at 900~GeV and 7~TeV, found an unavoidable tension between this data and the rest. Accordingly, this data was excluded from the fits. Whether this reflects a problem with this dataset or with the PYTHIA MPI model is a judgement for users to make!

### Field & Stuart Run I underlying event analysis. (CDF_2001_S4751469)

Spires | Phys.Rev.D65:092002,2002 | FNAL-PUB 01/211-E

The original CDF underlying event analysis, based on decomposing each event into a transverse structure with toward'', away'' and transverse'' regions defined relative to the azimuthal direction of the leading jet in the event. Since the toward region is by definition dominated by the hard process, as is the away region by momentum balance in the matrix element, the transverse region is most sensitive to multi-parton interactions. The transverse regions occupy $|\phi| \in [60\degree, 120\degree]$ for $|\eta| < 1$. The pT ranges for the leading jet are divided experimentally into the min-bias' sample from 0--20 GeV, and the JET20' sample from 18--49 GeV.

### Two jet triply-differential cross-section (CDF_2001_S4517016)

Spires | Phys.Rev.D64:012001,2001 | doi:10.1103/PhysRevD.64.012001 | arXiv:hep-ex/0012013

A measurement of the two-jet differential cross section, $\mathrm{d}^3\sigma/\mathrm{d}E_T \, \mathrm{d}\eta_1 \, \mathrm{d}\eta_2$, based on an integrated luminosity of $86 \mathrm{pb}^{-1}$. The differential cross section is measured as a function of the transverse energy, $E_\perp$, of a jet in the pseudorapidity region $0.1 < |\eta_1| < 0.7$ for four different pseudorapidity bins of a second jet restricted to $0.1 < |\eta_2| < 3.0$.

### CDF pseudorapidity distributions at 630 and 1800 GeV (CDF_1990_S2089246)

Spires | Phys.Rev.D41:2330,1990 | doi:10.1103/PhysRevD.41.2330

Pseudorapidity distributions based on the CDF 630 and 1800 GeV runs from 1987. All data is detector corrected. The data confirms the UA5 measurement of a $\d{N}/\d{\eta}$ rise with energy faster than $\ln{\sqrt{s}}$, and as such this analysis is important for constraining the energy evolution of minimum bias and underlying event characteristics in MC simulations.

### CDF transverse momentum distributions at 630 GeV and 1800 GeV. (CDF_1988_S1865951)

Spires | Phys.Rev.Lett.61:1819,1988 | doi:10.1103/PhysRevLett.61.1819

Transverse momentum distributions at 630 GeV and 1800 GeV based on data from the CDF experiment at the Tevatron collider.
