Title: New results on charged particle production as a function of the soft 
event activity in pp, p-Pb and Pb-Pb collisions at sqrt(sNN) = 5.02 TeV with 
ALICE

Abstract:

Following the approach of the CDF collaboration, the charged-particle number 
and summed-pT densities are measured as a function of the leading-particle 
transverse momentum (ptrigT). These quantities are studied in three topological 
regions: toward, away and transverse. The toward and away regions contain the 
jet fragments, whereas the transverse region is the most sensitive to the 
underlying event. The particle densities are measured in pp and p-Pb collisions 
at the same nucleon-nuclei center-of-mass energy. Comparisons between particle 
densities in pp and p-Pb collisions at the same ptrigT will be shown. In 
addition, the transverse momentum spectra measured in each topological region 
for pp, p-Pb and Pb-Pb collisions at sqrt(sNN)=5TeV will be presented. The 
evolution of the pT spectral shapes with multiplicity in the transverse region 
will be discussed. All measurements are compared with general purpose 
QCD-inspired MC event generators.
