ข้อมูลเชิงลึก - Anomaly Cancellation in Quantum Field Theory
Bµν를 이용한 Green-Schwarz 메커니즘으로 mod-2 변칙성을 제거할 수 있는 조건
8차원 N=1 Sp(n) 게이지 이론에서 나타나는 mod-2 변칙성은 Bµν 필드를 도입한 Green-Schwarz 메커니즘을 통해 제거될 수 있는 반면, 4차원 SU(2) 및 Sp(n) 게이지 이론의 mod-2 Witten 변칙성은 같은 방식으로 제거될 수 없다.
Bµνを用いたGreen-Schwarz機構によるmod-2アノマリーのキャンセル
8次元N=1 Sp(n)ゲージ理論のmod-2アノマリーは、Bµν場を用いたGreen-Schwarz機構によってキャンセルできるが、4次元SU(2)およびSp(n)ゲージ理論のmod-2 Wittenアノマリーはこの方法ではキャンセルできない。
Cancelling Mod-2 Anomalies in 8d Sp(n) Gauge Theory Using the Green-Schwarz Mechanism with Bµν: A Detailed Analysis
While the notorious Witten anomaly of 4d SU(2) and Sp(n) gauge theories remains uncanceled by introducing an antisymmetric tensor field H3, the mod-2 anomalies in 8d N=1 Sp(n) gauge theory can be completely canceled by employing a specific configuration of the H3 field and leveraging the Green-Schwarz mechanism.
