标题： On O(N)-Symmetric Gauged $φ^6{}_{2+1}$ Theory with Chern-Simons Term

摘要： 我研究了Chern-Simons耦合对具有Chern-Simons项的U(1)规范理论在$2+1$维高能行为的影响，该理论为$\eta(\phi^\dagger\phi)^3$。 有效势和$\beta$函数针对$\eta$被计算到$1/N$展开的次领头阶，作为$\theta$（Chern-Simons耦合）的函数。 对于所有$\theta$，发现该理论在高动量时趋于不稳定区域。 briefly讨论了$\theta$的辐射校正。 显示英文摘要

摘要： I investigate the effects of the Chern-Simons coupling on high-energy behavior in $2+1$ dimensional U(1) gauged $\eta(\phi^\dagger\phi)^3$ theory with a Chern-Simons term. The effective potential and the $\beta$ function for $\eta$ are calculated to the next-to-leading order of the $1/N$ expansion as functions of $\theta$ (the Chern-Simons coupling). For all $\theta$, the theory is found to be driven to instability region at high momenta. It is briefly discussed on radiative corrections to $\theta$.
