Essay Abstract

We especulate on the dynamics of charged photons admitting a hypothetical non-neglible photon charge Q_\gamma, albeit our limited understanding of extragalactic magnetic fields and of the expansion of the universe lead to uncertainties on its bound. We found a wavelength for the charged photons proportional to \sqrt{Q_\gamma /N_p}, where N_p is their number density. The light waves frequencies being of the order of the cosmic rays (>10^19 Hz).

If photons carried charge there would be vacuum anomalous scattering at a large amplitude focus such as as the National Ignition Facility. Calculate the number of NIF photons: 1.8 megajoules at 351 nm for 225 TW delivered at the focus. "Anomalous" means in excess of modeled Phys. Rev. 46 1087 (1934) and observed Phy. Rev. Lett. 79 1626 (1997). One suspects your thesis is already disproven.

Eppur: "Intense electromagnetic pulses of astrophysical origin (supernova) can lead to very energetic photons via bremsstrahlung of temporarily accelerated electrons while still in the pulse". In this view, the high-energy photons could transfer some energy to other charged particles. Phys. Rev. Spec. Top. Accelarators and Beams, 2 121301 (1999).

Hi Enrique

I like educated guesses, but they're of most value when they can be tested.

It was an educated guess that long range conserved photons like the ones we see travelling short distances, can travel 10bn light years across space at a constant speed. We have since become more educated.

I beleive Lena Hau and co have also looked for them in the BEC they've trapped them in at Harvard, but none could be found, and they had to let the light go in the end. (it went straight back to 'c' of course!!).

I have a real fear you're guessing at the characteristics of the Quark! Beware the apparently benign rule of the ruling paradigm!

I appreciate your comment Peter.

A guess ceases to be a guess, until it is tried. A trial is done in a framewrok of facilities. Quarks with electric charge properties

are produced in particle accelerators (and by high energy collisions of cosmic rays). There may not be trials for not having thought of them.

Intuition can motivate the search; and practice can prevent it.
