First, greetings from newbie to "staff"(adsbygoogle = window.adsbygoogle || []).push({});

Now, let's start:

Since some days I'm struggling a little bit with this paper: http://jmp.aip.org/resource/1/jmapaq/v5/i9/p1204_s1?isAuthorized=no [Broken] , especially with two questions:

1) On page 1205, II, A (right column): What does [itex]\tilde v B \gamma_5 [/itex] mean? The gamma 5 matrix isn't the problem, but what is the B and the tilde?? For me the "transpose-conjugate" of a (Dirac-)spinor should be more simply like [itex]v^{\dagger}\gamma_0[/itex].

2) Some lines later one finds the "basic equation". Isn't the term [itex]c_{\mu \nu} \gamma^{\mu \nu}[/itex] there equal to zero?

Thanks in advance.
