摘要:

我们分析了基于γ-e碰撞的紧凑型直线对撞机在Randall-Sundrum模型中寻找Radion的潜力,其中额外维度的紧致化半径由Radion稳定,Radion是一个比引力子Kaluza-Klein态轻的标量场。本文详细计算了高能γ-e对撞机中电子束极化时的放射子产生。数值计算表明,如果放射子质量不太重,质量级为GeV,那么在未来的对撞机上,在高极化度下,反应可以给出可观测的截面。

英文摘要:

We analyze the potential of Compact Linear Colliders based on the γ-e collisions to search for the radion in the Randall-Sundrum model, where compactification radius of the extra dimension is stabilized by the radion, which is a scalar field lighter than the graviton Kaluza-Klein states. The radion production in the high energy γ-e colliders with the polarization of the electron beams are calculated in detail. Numerical evaluation shows that if the radion mass is not too heavy with the mass order of GeV then the reaction can give observable cross section in future colliders at the high degree of polarization.
