special relativity

Please tell me if we could consider
L=gL(0)
m=gm(0)
g Lorentz factor
as experimental facts?

They have been verified by experiment if that's what you are asking. The first has been verified in the Michelson-Morely experiment, though the measurement was a kind of "null" result. (They were trying to measure the effects of the aether, but couldn't detect it. Their results, though, corroborated the Lorentz contraction, which is essentially the first equation you listed. I do not know of an experiment that explicitly tests the second equation, but the equation is used every time a particle accelerator is turned on and if it wasn't correct then the particles wouldn't behave as expected.
