The Sub-Atomic Particle Zoo

My scientific friend Phyzz went to the zoo recently, and to her delight found a new section devoted to sub-atomic particles. She gives some advice on what to do, and what not to do, if you go along to have a look:

Please don’t give buns to the Boson.
When you visit the particle zoo.
And avoid feeding figs
To the one known as Higgs,
For the keepers hate sweeping up poo.

Avoid having lunch with the Lepton,
You might be leapt on if you do.
But the Tau, for some hay,
Will point out the way,
While the Muon will just stand and chew.

The Quarks in the duck pond are dabbling,
Bottoms up and tops down, two by two.
And the grumpy-faced Gluon
Is giving his view on
What’s right, and what’s wrong, and what’s new.

When you pass by the hadrons and mesons,
If you’ve time and there isn’t a queue.
Can you ask them with tact,
How they all interact,
‘Cause I honestly haven’t a clue.

Sub-atomic particles are particles which are smaller than atoms. The elementary sub-atomic particles currently known include six types of Quark (called Up, Down, Bottom, Top, Strange and Charm), six types of Lepton (including the Electron, Muon and Tau), twelve types of Boson, including eight Gluons, plus the famous Higgs Boson. The elementary particles can combine to form composite sub-atomic particles such as protons, neutrons, hadrons, baryons and mesons.
