Possible decays of buttomonium

In summary, the possible decays of bottomonium b\bar{b} depend on weak and electromagnetic interactions, which can result in final quark-anti-quark pairs or lepton-anti-lepton pairs, respectively. However, these interactions are suppressed in the case of bottomonium with a mass below the one needed to form b-mesons. The three gluon involving OZI suppressed decay may still be stronger in this scenario. The spin of the particle also plays a role in its decay, as seen with Υ(1s) preferring to decay to three gluons.

Hello, I need some help understanding the possible decays of buttomonium b[itex]\bar{b}[/itex].

If I consider weak and electromagnetic interaction I could get final quark-anti-quark pairs, by simply annihilating b[itex]\bar{b}[/itex], or lepton-anti-lepton pairs (the neutral ones only with Zo resonance).
So why are we looking for strong interaction? They are stronger, but also suppressed in this case, if we assume the mass of b[itex]\bar{b}[/itex] is below the one to from b-mesons.

So is it the case that the three gluon involving OZI suppressed decay is still stronger then the weak and EM interaction?

Thank you!

Which bottomonium? The annihilation to two quarks or leptons via a virtual photon depends on the spin of the particle.

As an example, Υ(1s) likes to decay to three gluons: http://pdg8.lbl.gov/rpp2013v2/pdgLive/Particle.action?node=M049

I was not thinking about a specific one. The link actually helps a lot thanks.
 

Related to Possible decays of buttomonium

What is buttomonium and why is it important to study its possible decays?

Buttomonium is a theoretical particle made up of two baryons, specifically a baryon and an antibaryon, composed of heavy quarks. It is important to study its possible decays because it could provide valuable insights into the strong nuclear force and the nature of subatomic particles.

What are the potential decays of buttomonium?

The potential decays of buttomonium include annihilation into two photons, decay into a charm-anticharm meson and a pion, and decay into a bottom-antibottom meson and a pion. There are also other possible decays depending on the specific composition of the buttomonium particle.

How are scientists studying the possible decays of buttomonium?

Scientists are studying the possible decays of buttomonium through high-energy particle collisions in particle accelerators. By analyzing the data from these collisions, scientists can look for evidence of buttomonium decays and study their properties.

What can the study of buttomonium decays tell us about the strong nuclear force?

The study of buttomonium decays can help us better understand the strong nuclear force, which is responsible for holding together the protons and neutrons in an atom's nucleus. By studying the interactions between the heavy quarks in buttomonium, scientists can gain insights into the strong nuclear force and its mechanisms.

Could the discovery of buttomonium have practical applications?

While the discovery of buttomonium itself may not have direct practical applications, the study of its possible decays and the nature of the strong nuclear force could lead to advancements in fields such as nuclear energy, materials science, and technology. Additionally, the techniques and technologies developed to study buttomonium could have broader applications in other areas of scientific research.
