With LyX 2.0, how to write the Dirac equation (barred p - m)\psi = 0 ?
(that notation means (\gamma_\mu p^\mu - m)\psi = 0)
Merci !
Thank you !

Try typing this in math mode:
\not\!p
The \not part gives you the barré, the \! is a negative thin space so
that the bar appear centred on the p.
Alternatively, you can
\usepackage{cancel}
in the preambel, and then in the text
\cancel{p}
