论文摘要
我们进一步考虑了质子内部和更普遍的Hadron内部的可能性,还有其他部分 - 张量子胶子,可以携带质子动量的一部分。张量子的电荷为零,例如胶子,但旋转较大。在质子内部,可以通过胶子发射张量子来产生张力的非零密度。最后的机制是非亚伯张量规理论的典型特征。 Gluon分裂的过程表明,中性部分携带的质子动量的一部分是在载体和张量纤维之间共享的。我们为Parton分布函数得出了正则化演化方程,这些方程考虑了这些新过程。特别是,这将允许以数值方式求解扩展的挖掘方程,并找出胶子和张力量之间的密度比。
We further consider a possibility that inside the proton and, more generally, inside the hadrons, there are additional partons - tensor gluons, which can carry a part of the proton momentum. The tensorgluons have zero electric charge, like gluons, but have a larger spin. Inside the proton a nonzero density of the tensorgluons can be generated by the emission of tensorgluons by gluons. The last mechanism is typical for non-Abelian tensor gauge theories. The process of gluon splitting suggests that part of the proton momentum that was carried by neutral partons is shared between vector and tensor gluons. We derive the regularised evolution equations for the parton distribution functions that take into account these new processes. In particular, this will allow to solve numerically the extended DIGLAP equations and to find out the ratio of densities between gluons and tensorgluons.
