质子自旋与张量胶子

Proton Spin and Tensorgluons

Spyros Konitopoulos, George Savvidy

摘要:

最近有人提出,在强子内部有额外的部分子--张量胶子--它们携带与胶子相同的电荷,但具有更大的自旋。非零密度的张量胶子可以通过胶子对张量胶子的辐射在核子内部产生。张量胶子可以和胶子一起携带一部分核子动量。因为张量胶子有更大的自旋,它们可以影响核子的自旋结构。我们分析了极化张量胶子密度对核子自旋的可能贡献。与胶子相比,这种贡献出现在第二个领先的顺序中,并且由于张量胶子的较大自旋而可以提供实质性的屏蔽效应。

英文摘要:

Recently it was suggested that inside the hadrons there are additional partons - tensorgluons - which carry the same charges as the gluons, but have larger spin. The nonzero density of tensorgluons can be created inside a nucleon by radiation of tensorgluons by gluons. Tensorgluons can carry a part of nucleon momentum together with gluons. Because tensorgluons have a larger spin, they can influence the spin structure of the nucleon. We analyse a possible contribution of polarised tensorgluon density to the spin of the nucleon. This contribution appears in the next to leading order, compared to the gluons and can provide a substantial screening effect due to the larger spin of tensorgluons.
