Pair-production is the event when a particle and anti-particle is created from a single photon. We don't see 2 or more photons participating in a single pair-production event. Further, it seems in all the events of energy-mass conversion, photons act independently.
Two or more photons can never participate in a single event.
Is this a right statement?
Starting from this -
I know it doesn't make any sense to mix the fundamental equations below. But I'm going to try it nevertheless.
1) de-broglie wave-length of matter, [itex]\lambda[/itex] = h[itex]/[/itex]mv
2) E = h[itex]\mu[/itex]
3) c=[itex]\mu\lambda[/itex]
The result is, E=mvc. [ This looks familiar to the mass-energy equivalence, E=mc2 ]
My questions,
1) We famously know with a particle with non-zero mass cannot have a a velocity equal to c. Can we conversely say a particle with zero mass cannot have a velocity not equal to c?
2) Is mass a 'slowed-down' energy quanta (photon)?
3) If an event reduce the velocity of a photon, does it get converted to mass?
4) Is this what happens in pair-production?
5) Is pair-production the only possible mechanism of creating mass? Can there be another mechanism of converting energy quanta to mass?
cheers!
