Nah, then flags would move according to us.

comment Confusion about Length Contraction (ex in Muon decay)
In case standing on Earth, we can put flag when muon starts and when muon ends - these flags will be motionless, only muon would move. We could change muon with particle with some structure, here we would observe Lorentz contraction for this structure. But distance between two flags won't change, they are motionless.

In fact, variables in Lorentz transformation are for measured values.

comment Confusion about Length Contraction (ex in Muon decay)
We don't have to - we already know the distance. If it will help, imagine it as already contracted and just measured.

I was just about to post the answer ;) congratz of fast explanation.

Geez, i don't see anything wrong here. Why we can't just answer this question?

comment $\gamma^5$ factor in Quantum Field Theory
In 3.4 chapter we have only description of $\gamma^5$ as a helicity operator. I still don't see how it works in interaction hamiltonian.
