    B0 = anti-bottom quark + down quark

    Bs0 = anti-bottom quark + strange quark

    Both have 0 total charge. More details in https://en.wikipedia.org/wiki/B_meson

    The title says "evidence" because it's only a 3 sigma. I.E., very interesting, but there is still a small chance that it's a fluke.
