Success !!
In 1994, after 17 years of trying at various accelerators, and nearly 10 years at the Tevatron, we finally found a grand total of 12 collisions that looked like they produced a top-antitop pair. Now there are more than 100.
And only 1 out of 1010 collisions produced a top-antitop pair.
Now that’s a needle in a haystack!
