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.
