Rho-Meson propagator at two-loop order in the Kroll-Lee-Zumino quantum field theory
… corrections. When it comes to describing hadronic physics, one might say, these one-loop results achieve moderate to excellent success. Where the one-loop results show less than impressive agreement with experiment, it seems plausible that the NNLO (two-loop) corrections would remedy the …

Precision measurement of neutron spin asymmetry An1 at large xBj using CEBAF at 5.7 GeV
… structure has remained one of the key issues of hadronic physics since the 1980's. Among the unsolved questions, the neutron spin structure in the valence quark region (the large Bjorken variable XBj region) is of particular interest. The few data that existed in the large XBj region are very …

Model-independent approaches to QCD and B decays
… interactions at the scales mb and ... from hadronic physics at AQCD by expanding in ratios of these scales. After a review of SCET, we construct a complete reparametrization-invariant basis for heavy-to-light currents in SCET at next-to-next-to-leading order in the power-counting expansion. …

Strongly coupled fermions on the lattice
… quark confinement, chiral symmetry breaking and hadronic physics. Correlation functions of hadronic operators and scattering matrix of hadronic states can be calculated in terms of fundamental quark and gluon degrees of freedom. Since lattice QCD is the only well-understood method for studying …

Electromagnetic Form Factors of Hadrons in the Space-Like Region
The theory of the strong force is unique amongst the known forces of nature in that the strength of its interactions grow with distance. It is postulated that this leads to the empirically observed colour con nement hypothesis. This hypothesis states that quarks and gluons, the fundamental degrees …

Gluon propagator in classical color field of colliding hadrons and its implications for hadronic cross sections
We review the Regge theory and the minijet model for pp and pp collisions. We show that, in the conventional minijet approach, the asymptotic behavior of the total cross section calculated using currently accepted gluon distribution function and perturbative QCD rises too rapidly when compared with …

Meson Photo-Couplings From Lattice Quantum Chromodynamics
<p>We explore the calculation of three-point functions featuring a vector current insertion in lattice Quantum Chromodynamics. These three-point functions, in general, contain information about many radiative transition matrix elements simultaneously. We develop and implement the technology …

Light (anti)nuclei production with ALICE at the Large Hadron Collider
… the harsh environment of the ultra-relativistic hadronic collisions and to study in details the characteristics of the QGP. ALICE has excellent tracking and Particle IDentification (PID) capabilities over a broad momentum range. This makes ALICE the most suited detector at the LHC to study light …

Measuring the Neutron Spin Asymmetry A1n in the Valence Quark Region in Hall C at Jefferson Lab
… components has been at the forefront of nuclear physics for decades. Due to the non-perturbative nature of Quantum Chromodynamics (QCD) - the theory describing how quarks and gluons bind together to form protons and neutrons - making absolute predictions of nucleon spin structure is generally …
