Anyone care to venture a guess at what we might be seeing here?
Could this be a Higgs boson decaying to one W,Z boson along with a collection of bottom quarks?
I don't think so. Higgs bosons are really unstable and I don't think it would get a measurable distance away from the centre before it decayed. In any case, W/Z bosons and bottom quarks are unstable themselves and would decay further. As a non-expert, my guess would be some sort of neutral meson decaying via the weak interaction.
