论文摘要
核子的横向和张量电荷在实验和理论上进行了积极研究，是强子物理学的基本量以及我们对细胞核结构的理解。已经观察到了基于现象学提取和晶格QCD计算计算的张量电荷值之间的一些张力。在这封信中，通过一个明确的例子，我们研究了通常在现象学参数化中采用的假设的作用，并且我们表明，通过放松其中的一些，可以缓解这种张力。
The transversity and the tensor charge of the nucleon, currently under active investigation experimentally and theoretically, are fundamental quantities in hadron physics as well as for our comprehension of the nucleon structure. Some tension between the values of the tensor charge, as computed on the basis of phenomenological extractions and lattice QCD calculations, has been observed. In this letter, by means of an explicit example, we study the role of assumptions, usually adopted in phenomenological parametrizations, and we show that, by relaxing some of them, such a tension could be eased.
