The scalar fields of supersymmetric theories in 4 spacetime dimensions are a set of complex fields (usually denoted by ##z^{\alpha}##). How can this be physically translated?(adsbygoogle = window.adsbygoogle || []).push({});

More precisely, we know that in 5D, those scalars are real, so what is that makes them real here but complex there?
