I saw this equation on one of the walls of my local physics library and I cannot make sense of it.
[tex]
L = \bar {q} (i \gamma ^{\mu} D_{\mu} - m_{q} ) q - \frac {1}{4} F^{a}_{\mu \nu} F^{\mu \nu} _{a}
[/tex]
I tried assuming that L was the Lagrangian, m was mass, F was the Faraday tensor, etc. but my assumptions were never consistent with dimensional analysis.
What is this?
Thanks.
