Hello. I would like to ask something that will help me understand a little better how we work with Dirac spinors' inputs....(adsbygoogle = window.adsbygoogle || []).push({});

I know that the dirac equation has 4 independent solutions, and for motionless particles, the (spinor) solutions are:

[itex] u_{+}=(1,0,0,0)^{T} [/itex] electron +1/2

[itex] u_{-}=(0,1,0,0)^{T} [/itex] electron -1/2

[itex] v_{+}=(0,0,1,0)^{T} [/itex] positron +1/2

[itex] v_{-}=(0,0,0,1)^{T} [/itex] positron -1/2

Now suppose that I write a solution as:

[itex] Ψ=(1,0,0,1)^{Τ}[/itex]

Does that mean that I'm having 2 particles (one positron and one electron) involved?
