核子的奇异性:我们学到了什么?

Strangeness in the nucleon: what have we learned?

A. W. Thomas, P. E. Shanahan, R. D. Young

摘要:

本文综述了奇异夸克对各种核子性质的贡献。在电磁形状因子的情况下,理论和实验之间的一致性水平是非常令人满意的,并给予我们相当大的信心,我们的能力,使可靠的计算内非微扰QCD。鉴于标量形状因子对探测中性伴子等暗物质候选者的重要性,我们特别强调了π-N和奇异夸克σ介子的确定。

英文摘要:

We review the state of our knowledge concerning the contribution of strange quarks to various nucleon properties. In the case of the electric and magnetic form factors, the level of agreement between theory and experiment is very satisfactory and gives us considerable confidence in our capacity to make reliable calculations within non-perturbative QCD. In view of the importance of the scalar form factors to the detection of dark matter candidates such as neutralinos, we place a particular emphasis on the determination of the pi-N and strange quark sigma commutators.
