由d(\vec e,e' \vec p,)n分裂得到的氘核非核子自由度

Non-nucleon degrees of freedom in the deuteron from the d(\vec e,e'\vec p,)n break-up

Alexander Kobushkin, Yurij Kutafin

摘要:

本文分析了氘中夸克自由度对d(\vec e,e' \vec p)n分裂中质子纵极化P_z'和横极化P_x '的贡献。结果表明,这种效应的作用方向是正确的,可以解释实验数据。我们预言,当p_m >200 MeV/c时,极化将发生定性变化,(i)极化变得强烈依赖于平面外角;(ii)在p_m ~200 MeV/c时,两种极化都出现了结构。

英文摘要:

We analyzed contribution of quark degrees of freedom in the deuteron to the longitudinal, P_z', and transverse, P_x', polarizations of the proton in the d(\vec e,e'\vec p)n break-up. It is demonstrated that such effects work in correct direction to explain experimental data. We predict that the polarizations should change qualitatively behavior at p_m >200 MeV/c, (i) the polarizations become strongly dependent on the out-of-plain angle and (ii) there appears a structure in the both polarizations at p_m ~200 MeV/c.
