I've been tasked with showing that a Lagrangian under a set of transformations changes by a time derivative. All has gone well, except I'm left with two remaining terms, that I am completely confident, aren't there by mistake (as the 16 terms that should be expected have all popped out with the correct signs etc). The two terms, I believe, probably cancel but I don't just want to speculate. Anyway, the two terms that remain are, [tex]W'' W' (ψ^*ε^* + εψ)[/tex] where W is the Superpotential (primes representing derivatives, w.r.t x) as a function of the spatial co-ordinate x. ψ represents the Superspace co-ordinate and epsilon represents the small change Grassmann parameter relevant to our transformation. Stars represent complex conjugates. Now, I will also add that ψ is a Grassmann number so we can rewrite the terms such that, [tex]W'' W' (ψ^*ε^* - ψε)[/tex] So, briefly put, do these two terms cancel one another out? If so, why? (also, please do not delete my post for not following the template, I didn't find it neccessary given that this is quite a small scale question) Thanks for your time, Physics forum!
