Rapidity evolution of observables at high energies using the Gaussian truncation
… Model arise from theoretical uncertainties in quantum-chromo-dynamics contributions to cross-sections measured at high-energy collider experiments. At high energies, the quantum-chromo-dynamics of particle collisions is well described through the use of the colour-glass condensate. In this …

Charge Symmetry Violation Quark Distributions via Precise Measurement of π+/π− Ratios in Semi-inclusive Deep Inelastic Scattering
… Symmetry Violation (CSV) to be less than 9%. In Quantum Chromo-Dynamics (QCD), charge symmetry is broken by the mass difference between the up and down quarks. CSV in the valence region can be extracted from precision measurements of the cross section ratio of charged pion production in …

Precision measurement of neutron spin asymmetry An1 at large xBj using CEBAF at 5.7 GeV
… Also, theoretical predictions based on Quantum Chromo-Dynamics (QCD) are difficult to carry out accurately in this non-perturbative region and having good experimental data is very important to test the models. Taking advantage of the polarized continuous-wave (CW) electron beam at …

2-d Di-hadron Correlations at √sN N = 2.76 TeV using the ALICE experiment
… (∼ 10−6s) after the Big Bang. The theory of Quantum Chromo Dynamics (QCD) predicts the formation of a primordial nuclear matter phase known as Quark Gluon Plasma (QGP) under these experimental conditions. This dissertation focuses on studying this QCD medium using data from the ‘A Large Ion …

Phase transitions in lattice gauge theories
… with the Monte Carlo results. In part II Quantum Chromo dynamics ( QCD) is studied at non-zero baryon density. The essential properties of QCD are reviewed, including the broken chiral symmetry of the QCD vacuum state. The current understanding of the deconfining and chiral symmetry …

Aspects of Nonperturbative Heavy Quark Physics
… and bottom quarks are an interesting corner of Quantum Chromo-Dynamics (QCD) due to the fact that their masses are much heavier than the typical QCD interaction energy ΛQCD. Due to this scale separation, it is possible to describe these heavy quarks by Effective Field Theories (EFTs) that …
