高能物理实验的离线计算

正高能物理研究组成物质的基本粒子及其相互作用规律,是物理学研究中的最前沿。当今,高能物理实验规模一般都很大,需要成百上千的科学家参加。高能物理实验的周期比较长,从实验设计到目标的实现通常会经历十几年甚至几十年的时间。实验产生的海量实验数据,需要借助先进的计算机技术来处理和分析,实验的需求也助推了计算机信息技术的不断发展。近年来,我国物理学家在以我为主的高能物理实验中取得了令人瞩目的成绩,其中包括北京正负电子对撞     

Inverse Scattering Transform in Squared Spectral Parameter for DNLS Equation under Vanishing Boundary Conditions

After a transformation, the inverse scattering transform for the derivative nonlinear Schr6dinger （DNLS） equation is developed in terms of squared spectral parameter. Following this approach, we obtain the orthogonality and completeness relations of free Jost solutions, which is impossibly constructed with usual spectral parameter in the previous works. With the help these relations, the Zakharov-Shabat equations as well as Marchenko equations of IST are derived in the standard way.
