Proton proton multiplicity distributions at the Relativistic Heavy Ion Collider.
Sagerer, Joseph F.

Proton proton multiplicity distributions at the Relativistic Heavy Ion Collider. - 241 p.

Adviser: David Hofman.

Thesis (Ph.D.)--University of Illinois at Chicago, 2008.

Measurements of global charged particle production in proton-proton collisions were performed using the PHOBOS detector at the Relativistic Heavy Ion Collider. Included is the first published measurement of the charged particle pseudorapidity densities at s = 410GeV. Both s = 410 and 200GeV measurements extend +/-5.4 units in pseudorapidity from 0. This is a greater pseudorapidity range than any previously available result at s = 200GeV. Each measurement was repeated for the total inelastic and non-single diffractive cross sections and with respect to the observed charged particle multiplicity in the PHOBOS Octagon detector.

520 $a Measurements of global charged particle production in proton-proton collisions were performed using the PHOBOS detector at the Relativistic Heavy Ion Collider. Included is the first published measurement of the charged particle pseudorapidity densities at s = 410GeV. Both s = 410 and 200GeV measurements extend +/-5.4 units in pseudorapidity from 0. This is a greater pseudorapidity range than any previously available result at s = 200GeV. Each measurement was repeated for the total inelastic and non-single diffractive cross sections and with respect to the observed charged particle multiplicity in the PHOBOS Octagon detector.
520 $a Comparisons to previously existing proton-proton collision data were made including direct comparisons to previously existing s = 200GeV proton-antiproton collisions. There exists good agreement among the inelastic results, but the PHOBOS non-single diffractive result is &sim;10% higher at mid-rapidity. Possible explanations for this discrepancy are studied.
520 $a The slopes of the charged particle pseudorapidity distributions were determined over a common fractional range of the beam rapidity. Total charged particle yields for the inelastic and non-single diffractive cross sections were calculated for both the total distribution and with respect to the PHOBOS Octagon observed charged particle multiplicity. A common growth in the slope with respect to increasing total charged particle yield of each Observed multiplicity's distribution scaled by the average distribution yield is observed. Similar slopes in previously existing data demonstrate this scaling over s = 23.4 to 900GeV.
520 $a Comparisons to heavy ion results in the PHOBOS detector are made. The matching of centrality binned Gold-Gold and Copper-Copper collisions with similar total charged particle yielding observed multiplicity selected proton-proton data is done. The charged particle pseudorapidity distributions of such matched data show a striking similarity.
