标题： Transversity and Lambda polarization

摘要： 两个相关的问题被讨论，这可能由目前和未来的COMPASS实验容易地进行研究。 第一个问题涉及横向极化的新领域，这是迄今为止完全未知的基本极化部分子分布。 第二个问题涉及极化半包容过程中Lambda的产生，通过测量Lambda的极化，可能会提供关于极化部分子分布和碎裂特性的新信息。 在横向极化的情况下，Lambda的探测为测量横向极化提供了一种新方法。 还讨论了在非极化过程中Lambda极化的有趣情况。 显示英文摘要

摘要： Two related issues are discussed, which might be easily explored by present and future COMPASS experiments. The first one deals with the new world of transversity, the fundamental polarized parton distribution so far totally unknown. The second issue concerns Lambda production in polarized semi-inclusive processes, with a measurement of the Lambda polarization, which might give novel information on distribution and fragmentation properties of polarized partons. In case of transverse polarization the detection of Lambda's gives access to a new way of measuring transversities. Also the interesting case of Lambda polarization in unpolarized processes is discussed.
