Book Description
ABSTRACT: This dissertation presents a measurement of event shape variables in proton-antiproton collisions at a center of momentum energy of 1.96 TeV. The observables studied are the transverse thrust and thrust minor, both defined over final state momenta perpendicular to the beam direction. These variables are calculated using unclustered calorimeter energy measured using the CDF-II detector at the Fermi National Accelerator Lab. In addition to differential distributions, we present the evolution of event shape mean values as a function of the leading jet Et. The data is compared to dedicated theoretical predictions (NLO+NLL) and subsequently to PYTHIA Monte Carlo with and without multiple parton interactions. In the presence of an underlying event the observables are found to significantly depart from the predictions of perturbative QCD.

Book Description
Underlying Event distributions are studied in events containing at least one charged particle jet produced in proton-proton collisions at sqrt(s) = 7 TeV. Jets are reconstructed from charged particles using the anti-Kt algorithm with radius parameter R = 0.6. The jet with the largest transverse momentum (pT) and.

Book Description
Measurements are presented of the production of primary K(S)0 and Lambda particles in proton-proton collisions at sqrt(s) = 7 TeV in the region transverse to the leading charged-particle jet in each event. The average multiplicity and average scalar transverse momentum sum of K(S)0 and Lambda particles measured at pseudorapidities abs(eta)
