Quadratic Twist-Noncommutative Gauge Theory

Area of Science:

• Theoretical Physics
• Quantum Field Theory
• String Theory

Background:

• Existing research on noncommutative gauge theories primarily addresses constant noncommutative structures.
• Limited understanding exists for actions of noncommutative 4D Yang-Mills theory beyond constant structures.

Purpose of the Study:

• To construct a novel action for Yang-Mills theory on a quadratically noncommutative spacetime.
• To explore the implications of this construction for supersymmetric Yang-Mills theory and string theory.

Main Methods:

• Development of a Yang-Mills theory action utilizing a Drinfeld twist.
• Application of the constructed action to supersymmetric Yang-Mills theory.

Main Results:

• Successfully constructed an action for Yang-Mills theory on a quantum-plane type noncommutative spacetime.
• Identified a candidate AdS/CFT dual for string theory on a deformed AdS_{5}×S^{5} background.

Conclusions:

• The developed action provides a new framework for studying quantum field theories on noncommutative spacetimes.
• The findings offer a potential string theory dual for a deformed AdS_{5}×S^{5} spacetime, expected to exhibit integrability in the planar limit.
