Ph.D. defence by Hans Hjersing Dalsgaard

Pseudorapidity Densities in p+p and Pb+Pb collisions at LHC measured with the ALICE experiment 

The pseudorapidity density of charged particles is a fundamental observable in heavy ion and proton-proton collisions. It enters model calculations of entropy and energy density and could be related to the initial conditions of the collisions. It is important for the study of the socalled Color Glass Condensate which may be formed initially in heavy ion collisions prior to the conjectured formation of a Quark Gluon Plasma. In this PhD thesis defence results will be presented that extend the measurement of the pseudorapidity density of charged particles at LHC energies to forward rapidities.
