A Sonnet about Helicity and Chirality

 
Out of concepts in physics, all so bright,
Helicity and chirality I seek to understand,
Forever intertwined, they come hand in hand,
And our imagination they so easily ignite.
 
Helicity shows, during a particle's flight,
If the spin is aligned against or toward
Chirality's way more abstract than that -
It's about what happens when γ5 and a spinor unite.
 
But oh, when one forgets about mass,
Like the neutrino that is just so fast and light,
Or even a particle that moves with the speed of light,
the two ideas converge as one, alas,
and helicity's up is chirality' right,
and vice versa- oh what a delight!
