1. Mini-Jet Production in Proton-Antiproton Interactions and Particle Production in Heavy-Ion Collisions
Abstract : The thesis is based on the data analysis and detector development of the EMU01/CERN, E863/BNL and UA1/CERN experiments. Particle fluctuations are studied with the scaled factorial moments in the fragmentation region of oxygen-induced emulsion interactions from 3.7 to 200 A GeV. READ MORE

2. QCD Phenomenology of Heavy Particle Dynamics
Abstract : In this thesis the phenomenology of Quantum Chromo Dynamics (QCD) is studied in a variety of circumstances from both perturbative and non-perturbative perspectives. The main emphasis is on the production and hadronization of heavy particles, specifically heavy quarks, gauge bosons, leptoquarks and supersymmetric particles. READ MORE

3. Λ/K0s Associated with a Jet in Central Pb–Pb Collisions at √sNN = 2.76 TeV Measured with the ALICE Detector
Abstract : In high energy heavy ion collisions, the QCD matter undergoes a phase transition to a hot and dense strongly coupled Quark Gluon Plasma, where quarks and gluons are deconfined in a volume of nuclear dimensions. At intermediate pT, 2 < p T < 8 GeV/c, a decoupling from pure hydrodynamical flow is observed, most noticeable in central collisions, demonstrated by the peak in the ratio of baryons to mesons, e.

4. Properties of Hadronization in e+e- -Annihilation
Abstract : Possible effects from colour interferences in strong interactions are discussed and investigated, and possible experimental signals in e+e- --> hadrons and e+e- --> W+W- --> hadrons are suggested. The observability of the signals depend on the relative probabilities of the occurrence of interferences, and can provide a measurement of the probabilities. READ MORE

5. Study of the production of π, K and p in pp collisions at √s = 13 TeV as a function of the Transverse Spherocity and the Relative Transverse Activity
Abstract : High-energy heavy-ion collisions allow the Quark-Gluon Plasma (QGP) production and study, a state of high-density QCD matter in which quarks and gluons are no longer confined inside hadrons for a very short time. Different observables reveal an enhanced production of strange hadrons, signatures of collective effects and opacity to jets due to the QGP formation. READ MORE
