標題: | A UV completion of scalar field theory in arbitrary even dimensions | 作者: | PEI-MING HO | 關鍵字: | Field theories in higher dimensions; Renormalization regularization and renormalons | 公開日期: | 十月-2009 | 卷: | 01 | 起(迄)頁: | 032 | 來源出版物: | JHEP | 摘要: | Following a previous work (hep-th/0410248), where a scalar field theory with a modified propagator and φ4 interaction in 4 dimensions is constructed to be UV-finite, unitary and Lorentz invariant, we discuss in this paper general φn theory in arbitrary even space-time dimensions. We show that the theory is still UV-finite, unitary and Lorentz invariant if the propagators are chosen to meet certain simple conditions depending on the space-time dimension but independent of n. We also comment that our model is reminiscent of string theory in the way UV divergence is avoided. © SISSA 2010. |
