 Greek letters are adjusted to always be italic and upright in math and text mode, respectively, using the \software{fixmath} \cite{fixmath} and \software{alphabeta} \cite{alphabeta} packages.
 This allows differentiations like
 \begin{align} \label{eq:greek}
-\sigma &= \unit[5]{fb} \ , & &\mbox{at \unit[5]{\sigma} C.L.} \ , & \mu &= \unit[5]{cm} \ , & l &= \unit[5]{\text \mu m} \ ,

 \end{align}
-and \eg to distinguish gauge $\nu$ and mass \nu\ eigenstates in models with massive neutrinos.
-Note that |\mathrm| and therefore |\unit| transform italic Greek character to seemingly random upright characters, this can be avoided by using |\unit{\text\mu m}|.
