Prove that the quantity [itex]2EN^2 dx^3[/itex] is a relativistic invariant.

2. Relevant equations

Well we want to prove that this quantity is the same in all inercial frames.

My doubt is with the energy transformation,

[tex]E=\gamma E_0[/tex]

does it transforms like that? If yes,

[tex]dx^3=\frac{dx_0^3}{\gamma}[/tex]

[tex]2EN^2 dx^3=2 \gamma E_0 N^2 \frac{dx^3}{\gamma}=2E_0 N^2 dx_0^3[/tex]

and its done...?

Thanks
