Noncommutative Quantum Field Theory: A Confrontation of Symmetries
M. Chaichian, K. Nishijima, T. Salminen +1
The concept of a noncommutative field is formulated based on the interplay between twisted Poincaré symmetry and residual symmetry of the Lorentz group. Various general dynamical r…
Gauge-Dependence of Green's Functions in QCD and QED
K. Nishijima, A. Tureanu
When all Green's functions are known in a given gauge we may raise a question of whether it is possible or not to derive the corresponding ones in a different gauge. The answer is…
Non-anticommutative Supersymmetric Field Theory and Quantum Shift
Masato Arai, Masud Chaichian, Kazuhiko Nishijima +1
Non-anticommutative Grassmann coordinates in four-dimensional twist-deformed N=1 Euclidean superspace are decomposed into geometrical ones and quantum shift operators. This decompo…
Connection Between Color Confinement and the Gluon Mass
M. Chaichian, K. Nishijima
It is argued that there are two phases in QCD distinguished by different choices of the gauge parameter. In one phase the color confinement is realized and gluons turn out to be ma…
An Interpretation of Noncommutative Field Theory in Terms of a Quantum Shift
M. Chaichian, K. Nishijima, A. Tureanu
Noncommutative coordinates are decomposed into a sum of geometrical ones and a universal quantum shift operator. With the help of this operator, the mapping of a commutative field…
Color Confinement and Massive Gluons
M. Chaichian, K. Nishijima
Color confinement is one of the central issues in QCD so that there are various interpretations of this feature. In this paper we have adopted the interpretation that colored parti…
