多重M2-Branes的非线性BF理论的Janus场论

Janus Field Theories from Non-Linear BF Theories for Multiple M2-Branes

Shijong Ryang

摘要:

我们对arXiv:0808.2473中描述N个M2-膜的包含偶数个全反对称张量M^{IJK}项的非线性BF拉格朗日量和arXiv:0809:0985中包含奇数个M^{IJK}项的两类非线性BF拉格朗日量的非传播B μ规范场进行积分.对于前者,我们直接导出了具有时空相关耦合常数的SU(N)动力学A_μ规范场所表示的DBI型拉格朗日量,而对于后者的低能展开式,我们迭代地进行了B_μ积分。对导出的Janus场论拉格朗日量进行了比较。

英文摘要:

We integrate the nonpropagating B_μ gauge field for the non-linear BF Lagrangian describing N M2-branes which includes terms with even number of the totally antisymmetric tensor M^{IJK} in arXiv:0808.2473 and for the two-types of non-linear BF Lagrangians which include terms with odd number of M^{IJK} as well in arXiv:0809:0985. For the former Lagrangian we derive directly the DBI-type Lagrangian expressed by the SU(N) dynamical A_μ gauge field with a spacetime dependent coupling constant, while for the low-energy expansions of the latter Lagrangians the B_μ integration is iteratively performed. The derived Janus field theory Lagrangians are compared.
