超子极化、横截性与LHC物理

Hyperon Polarization, Transversity and LHC Physics

Gary R. Goldstein, Simonetta Liuti

摘要:

在LHC的高能量下,自旋物理学中长期存在的难题可以得到解决。通过重超子的产生能观察到大的s夸克和c夸克极化吗?顶夸克被认为具有显著的极化-单自旋不对称性。这样的观测如何能分辨出可能的QCD机制呢?Leptoproduction提供了一种进入这些机制的手段。TMD、GPD和断裂函数都为极化现象提供了不同的模型方法。将描述其含义。

英文摘要:

Longstanding puzzles in spin physics can be confronted at the high energies of the LHC. Will large s-quark and c-quark polarization be observed through heavy hyperon production? Top quarks are expected to have significant polarization - single spin asymmetries. How can such observations sort out possible QCD mechanisms? Leptoproduction provides a means to access those mechanisms. TMDs, GPDs and Fracture Functions all provide different model approaches to the polarization phenomena. Their implications will be described.
