non-Abelian gauge theory
Technical term in theoretical physics; refers to gauge theories where the gauge group is non-commutative, such as Yang–Mills theory.
Non-Abelian gauge theory forms the basis of the Standard Model of particle physics.
Gauge theory in general; 非可換ゲージ理論 specifically refers to the non-Abelian case.
Abelian gauge theory, such as quantum electrodynamics, where the gauge group is commutative.
Compound of 非可換 (non-commutative) + ゲージ理論 (gauge theory). The term is a direct calque from English 'non-Abelian gauge theory'.
