DIS中的非粒子物理

Unparticle Physics in DIS

Gui-Jun Ding, Mu-Lin Yan

摘要:

4D-共形场论中与非平凡红外不动点有关的非粒子填充方案是最近由Georgi提出的。我们在深度非弹性散射(DIS)过程中说明了它的物理效应。研究了DIS中与宇称破坏不对称性有关的一种可能的非粒子信号。发现这种奇偶性破坏信号的行为对非粒子的尺度维数$d_{\cal U}$的值很敏感。

英文摘要:

The unparticle stuff scenario related to the notrivial IR fixed point in 4D-conformal field theory is recently suggested by Georgi. We illustrate its physical effects in Deep Inelastic Scattering (DIS) process. A possible signal of unparticle related to parity violation asymmetry in DIS is investigated. It is found out that the behavior of this parity violation signal is sensitive to the value of the scale dimension $d_{\cal U}$ of unpaticle.
