If they were going to discover it, they would have done it by now. Why are they still in the race? If they were going to discover it, they would have done it by now.

I didn't know about that usage of mA. Thanks. I didn’t know about that usage of mA.

He pointed out that this is actually a piece of jargon used by the accelerator physicists and that he had left it in the slide by mistake. He explained as follows: "The Accumulator circumference and antiproton revolution time is such that 1 mA of antiprotons corresponds to an intensity of 10^10 antiprotons. So, a stacking rate in mA/hr = 10^10 antiprotons/hr." Thanks for pointing this out--we've corrected it above.
