RE: La matière noire défiée par les étoiles à neutrons

Mesons are particles made of a quark-antiquark pair and are not baryons. Their net baryon number is indeed 0 (+1 for the quark and -1 for the antiquark).

Here, when I talk about baryonic dark matter, we really talk about new particles that for some reasons possess a baryon number. But they are not made of quarks.

I hope this clarifies.

    That means; mesons have only two quarks?

    Thanks a lot for the clarification and quick lectures sir.

      One quark and one antiquark to be precise.
