¨ Zero “Transverse” Charged Particles: If there are no charged particles in the “transverse”

particles in the “transverse” region then the event is not used in constructing the “transverse”
average pT.

“transMIN” & “transDIF”
¨ The “toward” region contains the leading “jet”, while the “away”
region, on the average, contains the “away-side” “jet”. The
“transverse” region is perpendicular to the plane of the hard 2-to-2
scattering and is very sensitive to the “underlying event”. For
events with large initial or final-state radiation the “transMAX”
region defined contains the third jet while both the “transMAX”
and “transMIN” regions receive contributions from the MPI and
beam-beam remnants. Thus, the “transMIN” region is very
sensitive to the multiple parton interactions (MPI) and beam-beam
remnants (BBR), while the “transMAX” minus the “transMIN” (i.e.
Jet #3
“transDIF”) is very sensitive to initial-state radiation (ISR) and
final-state radiation (FSR).
“TransMIN” density more sensitive to MPI & BBR.

and “transDIF” charged particle and PTsum densities (pT > 0.5
GeV/c, |η| < 0.8) in proton-antiproton collisions at 300 GeV, 900

and “transDIF” charged particle and PTsum densities (pT > 0.5
GeV/c, |η| < 0.8) in proton-proton collisions at 900 GeV and 7 TeV
(M. Zakaria analysis). The “transMAX”, “transMIN”, and
“transDIF” are not yet approved so I can only show “transAVE”
which is approved.

Summary & Conclusions
¨The “transverse” density increases faster with center-of-mass energy
than the overall density (Nchg ≥ 1)! However, the “transverse” =
“transAVE” region is not a true measure of the energy dependence of
MPI since it receives large contributions from ISR and FSR.
¨The “transMIN” (MPI-BBR component) increases much faster with centerof-mass energy than the “transDIF” (ISR-FSR component)! Previously we
only knew the energy dependence of “transAVE”.
We now have at lot of MB & UE data at
300 GeV, 900 GeV, 1.96 TeV, and 7 TeV!
We can study the energy dependence
more precisely than ever before!
¨Both PYTHIA 6.4 Tune Z1 (CTEQ5L) and PYTHIA 6.4 Tune Z2*
(CTEQ6L) go a fairly good job (although not perfect) in describing the
energy deperdence of the UE!
