dirac matrices and QFT

hello all

i'd like to name matrices \sigma^{x} and \gamma^{2} (latex notation) but
of course, Mathematica interprets the x and 2 as exponents.  

is there a way of using superscripts to distinguish matrices?  

also, any packages out there for dirac, klein gordon or quantum field
theory? don't now what i'm looking for per se, just curious if anyone's
written packages which might be useful in basic calculations.  

pete
