Inside the proton, the ‘most complicated thing you could possibly imagine’

What’s interesting is that there’s a net charm content: there are more charm quarks to be found than anti-charms.

Given that charm quarks are heavier than the proton, you’d expect to only find them in deep inelastic collisions when they are produced in pairs with an anti-quark, so it is surprising that there’s an asymmetry.

Wait, what? I read the article as saying that it's an open question whether there's a charm asymmetry.
