Evaluation of Multiloop Diagrams via Lightcone Integration
Y. J. Feng, C. S. Lam
We present a systematic method to determine the dominant regions of internal momenta contributing to any two-body high-energy near-forward scattering diagram. Such a knowledge is u…
Generalized Background-Field Method
Y. J. Feng, C. S. Lam
The graphical method discussed previously can be used to create new gauges not reachable by the path-integral formalism. By this means a new gauge is designed for more efficient tw…
Multiple Reggeon Exchange from Summing QCD Feynman Diagrams
Y. J. Feng, C. S. Lam
Multiple reggeon exchange supplies subleading logs that may be used to restore unitarity to the Low-Nussinov Pomeron, provided it can be proven that the sum of Feynman diagrams to…
Cut Diagrams for High Energy Scatterings
Y. J. Feng, O. Hamidi-Ravari, C. S. Lam
A new approach is introduced to study QCD amplitudes at high energy and comparatively small momentum transfer. Novel cut diagrams, representing resummation of Feynman diagrams, are…
DIAGRAMMATIC ANALYSIS OF QCD GAUGE TRANSFORMATIONS AND GAUGE CANCELLATIONS
Y. J. Feng, C. S. Lam
Diagrammatic techniques are invented to implement QCD gauge transformations. These techniques can be used to discover how gauge-dependent terms are cancelled among diagrams to yiel…
String Organization of Field Theories: Duality and Gauge Invariance
Y. J. Feng, C. S. Lam
String theories should reduce to ordinary four-dimensional field theories at low energies. Yet the formulation of the two are so different that such a connection, if it exists, is…
