全息QCD中Chern-Simons项诱导的光生作用

Photoproduction through Chern-Simons Term Induced Interactions in Holographic QCD

S. K. Domokos, H. R. Grigoryan, J. A. Harvey

摘要:

我们采用自上而下和自下而上的全息QCD对偶模型来计算由五维Chern-Simons项引起的顶点函数和耦合。我们利用这些耦合来研究$f_1$介子的光生。陈-西蒙斯项诱导的相互作用导致入射光子的偏振和最终态$f_1$介子之间的简单关系,这应该允许从竞争过程中明确分离这种相互作用。

英文摘要:

We employ both top-down and bottom-up holographic dual models of QCD to calculate vertex functions and couplings that are induced by the five dimensional Chern-Simons term. We use these couplings to study the photoproduction of $f_1$ mesons. The Chern-Simons-term-induced interaction leads to a simple relation between the polarization of the incoming photon and the final state $f_1$ meson which should allow a clear separation of this interaction from competing processes.
