冷核介质中强子化过程的研究

Study of the hadronization process in cold nuclear medium

N. Akopov, L. Grigoryan, Z. Akopov

摘要:

利用改进的双尺度模型对DESY的HERMES实验的半包容深度非弹性散射(SIDIS)数据进行拟合。核靶上的强子多重数与氘靶上的强子多重数之比通常被选为可观测的。双参数拟合符合$χ^2$准则。最佳值的参数,然后用于计算核的多重数比的强子不包括在拟合过程中。

英文摘要:

The improved two-scale model is used to perform the fit to the semi-inclusive deep-inelastic scattering (SIDIS) data of HERMES experiment at DESY on nuclear targets. The ratio of hadron multiplicity on nuclear target to the deuterium one is chosen as observable, as usually. The two-parameter's fit gives satisfactory agreement with the data in term of $χ^2$ criterium. Best values of parameters are then used to calculate the nuclear multiplicity ratio for the hadrons not included in the fit procedure.
