摘要
强子-强子碰撞中高横动量喷注的产生对夸克之间新接触相互作用的存在很敏感。如果质子极化可用，则在大的横动量下单喷注产生中某些宇称破坏的自旋不对称性的测量将补充通常对偏离预期QCD截面的搜索。同时，可以获得关于新相互作用手征结构的独特信息。在此背景下，我们比较了计划中或已提出的各种和对撞机在额外要求束流极化条件下的潜力。

备注
Latex file, 9 pages and 1 ps fig, definition of the subprocess variables and one example of the effect of new contact terms on the parity violating spin asymmetry are added. Eq. 8 (now eq. 9) and the following equation are changed, giving better bounds in the polarized pp case (new figure)
