We report measurements of the production cross sections of charged pions, kaons, and protons as a function of fractional energy, the event-shape variable called thrust, and the transverse momentum with respect to the thrust axis. These measurements access the transverse momenta created in the fragmentation process, which are of critical importance to the understanding of any transverse momentum dependent distribution and fragmentation functions. The low transverse momentum part of the cross sections can be well described by Gaussians in transverse momentum as is generally assumed but the fractional-energy dependence is non-trivial and different hadron types have varying Gaussian widths. The width of these Gaussians decreases with thrust and shows an initially rising, then decreasing fractional-energy dependence. The widths for pions and kaons are comparable within uncertainties, while those for protons are significantly narrower. These single-hadron cross sections and Gaussian widths are obtained from a $558\,{\rm fb}^{-1}$ data sample collected at the $Υ(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider.

Search for the Theta(1540)+ pentaquark using kaon secondary interactions at Belle
利用Belle探测器材料中的K介子二次相互作用，我们寻找包含性和排他性的Theta（1540）+的产生。我们将90% C. L.的上限设定为2.5%。关于包括Theta（1540）+与Lambda（1520）在内的产生截面的比率。我们还寻找了Theta（1540）+作为电荷交换反应K+ n -> pKs的中间共振。在90% C. L.处，γ（Theta+）的上限<0.64MeV。m（Theta+）=1.539MeV。这些结果是从KEKB非对称能量e+e-对撞机上Belle探测器在Upperion（4S）共振附近收集的397/fb数据样本中获得的。
