Using Lamor's formula, can someone tell me how much radiation is emitted by a particle accelerator or by the collision of two photons? It requires a 4 momentum vector which I'm not very acquainted with. Thanks :)

I assume you are asking for an elaboration / direct calculation of this answer to your previous question? – Codename 47 Mar 20 '19 at 11:51

I don't think that anyone has ever observed any Delbruck (photon-photon) scattering directly. Certainly not in a terrestrial accelerator. – mike stone Mar 20 '19 at 12:24

Codename 47, haha don't call me out like that but yes. I have to get this project done very soon and I'm struggling with it. – Physics_gurl Mar 20 '19 at 12:32

Photon photon interactions are practically non existent , they have very small probability of collision, unless very high energy . https://en.wikipedia.org/wiki/Photon-photon_scattering – anna v Mar 20 '19 at 14:12

Larmor's formula is a rule for the computation of EM-radiation power of a moving electrical-charged particle, however, photons have no charge, so it cannot be applied. Or do you mean protons ?? – Frederic Thomas Mar 20 '19 at 15:03

https://en.wikipedia.org/wiki/Larmor_formula#Non-covariant_form shows the formula without using four-vectors – G. Smith Mar 20 '19 at 17:42
