Thank you so much, this explained a lot. I have a confusion going on about may things, but at least some pieces fell in place now.

I don't think you can say a=g in your first example, since the acceleration of the rod is not specified. The rod lies in the xy-plane (like on a table), and has a force acting upon it making it slide, and this force causing it to accelerate is not specified. So therefore your Lagrangian in...

OK, sorry for the spare comments on my notation. \theta \bar{\theta} are Grassmann numbers, and I think this is where my confusion is. They are anticommuting c-numbers, so in my head I am thinking it is irrelevant where I put them in my expression as long as the order among them is the same. Of...

Hello. There is one thing I can not find the answer to, so I try here. For instance, writing a general superfield on component form, one of the terms appearing is: \theta \sigma^\mu \bar{\theta} V_\mu My question is if one could have written this as \theta \bar{\theta} \sigma^\mu V_\mu ...
