Higher Fock sectors in Wick-Cutkosky model
V. A. Karmanov, Dae Sung Hwang
In the Wick-Cutkosky model we analyze nonperturbatively, in light-front dynamics, the contributions of two-body and higher Fock sectors to the total norm and electromagnetic form f…
Many-body Fock sectors in Wick-Cutkosky model
Dae Sung Hwang, V. A. Karmanov
In the model where two massive scalar particles interact by the ladder exchanges of massless scalar particles (Wick-Cutkosky model), we study in light-front dynamics the contributi…
Light-Cone Representation of the Spin and Orbital Angular Momentum of Relativistic Composite Systems
Stanley J. Brodsky, Dae Sung Hwang, Bo-Qiang Ma +1
The matrix elements of local operators such as the electromagnetic current, the energy momentum tensor, angular momentum, and the moments of structure functions have exact represen…
Nonabelian Topological Mass Generation in 4 Dimensions
Dae Sung Hwang, Chang-Yeong Lee
We study the topological mass generation in the 4 dimensional nonabelian gauge theory, which is the extension of the Allen 's work in the abelian theory. It is crucial to…
BRST Quantization of Gauge Theory in Noncommutative Geometry: Matrix Derivative Approach
Chang-Yeong Lee, Dae Sung Hwang, Yuval Ne'eman
The BRST quantization of a gauge theory in noncommutative geometry is carried out in the ``matrix derivative" approach. BRST/anti-BRST transformation rules are obtained by applying…
