额外维模型中的新正则化与宇宙学常数的重整化群流

New Regularization in Extra Dimensional Model and Renormalization Group Flow of the Cosmological Constant

Shoichi Ichinose

摘要:

在{ \it warped}几何中计算了5D标量理论的Casimir能量。提出了一种新的正则化方法,称为{ \it球格正则化}。正则化配置是{ \it闭弦类}。我们数值计算了$\La$(4D UV截止)、$\om$(5D体积曲率、翘曲参数)和$T$(额外空间红外参数)对Casimir能量的依赖性。5D Casimir能量是在{ \it适当重整化过程}之后获得的{ \it}。{ \it扭曲参数} $\om$受到{ \it重整化效应}的影响。我们研究宇宙学常数问题。

英文摘要:

Casimir energy is calculated for 5D scalar theory in the {\it warped} geometry. A new regularization, called {\it sphere lattice regularization}, is taken. The regularized configuration is {\it closed-string like}. We numerically evaluate $\La$(4D UV-cutoff), $\om$(5D bulk curvature, warp parameter) and $T$(extra space IR parameter) dependence of Casimir energy. 5D Casimir energy is {\it finitely} obtained after the {\it proper renormalization procedure.} The {\it warp parameter} $\om$ suffers from the {\it renormalization effect}. We examine the cosmological constant problem.
