For someone that Wikipedia's a lot of this stuff, does someone know if this type of spin asymmetry is in any sense related to CP violation? [1] As soon as I read the article I thought of CP violation and I'm assuming this is basically the "P" violation.
Finally, reading this article actually triggered a totally different question:
"Using the electron accelerator at Thomas Jefferson National Accelerator Facility in Newport News, Virginia, the researchers shined 170 billion electrons on a target of liquid deuterium over 2 months in 2009."
Shined or shone? Turns out to be quite the discussion topic (e.g., [2][3][4])!
