Photon-plasmon-photon interaction
Physical Review A, 1991A theory of photon-plasmon-photon three-wave interaction is presented. An electromagnetic wave launched into the plasma turbulence interacts through the wave-particle interaction resulting in the emission of an electromagnetic wave with frequency up-shifted.

Effective photon theory and photon-photon scattering
Journal of Quantitative Spectroscopy and Radiative Transfer, 1981Abstract It is shown that the assumptions made by Eimerl in deriving the unusually high photon-photon scattering cross section from the effective photon theory of Panarella are unfounded.

Nuclear Physics B - Proceedings Supplements, 1988
Recent results in γγ physics are presented. They include a number of new measurements of the γγ widths of members of the JPC = 0−+ and 2++ SU(3) nonets, a search for 0-+ radial excitations, studies of low mass ππ production and new results in the measurements of exclusive βc and inclusive D∗± production.

The scattering of photons by photons
Il Nuovo Cimento, 1965The general expressions for the five independent amplitudes of photon-photon scattering are given in a rather compact form. It has been shown in detail, in a previous paper (1), that this result is easily obtained for all the values of the energy and of the angle with the aid of the dispersion relations techniques.

Light is strictly connected with life, and its presence is fundamental for any living environment. Thus, many biological mechanisms are related to light interaction or can be evaluated through processes involving energy exchange with photons. Optics has always been a precious tool to evaluate molecular and cellular mechanisms, but the discovery of ...

To Scatter a Photon by a Photon
American Journal of Physics, 1966This paper gives a more detailed description of the “x-ray-flashbulb” experiment for observing the scattering of light by light in vacuum. It is shown here that at least ten to twenty scattering events can be initiated by two x-ray flashbulbs, properly oriented and synchronized to flash together in an appropriate experimental arrangement.

Photon-photon scattering in effective-photon theory
Journal of Quantitative Spectroscopy and Radiative Transfer, 1978Abstract Effective photon theory of laser-induced gas breakdown is shown to imply a very large photon-photon scattering cross section in the vacuum, of the order of 10 -22 cm 2 . This could be seen using crossed laser beams of moderate intensity, about 1 MW/cm 2 .

AIP Conference Proceedings, 1980
I review recent progress (mostly theoretical) in our knowledge of photon‐photon interactions at high energies, concentrating on resonance production and on reactions which expose the pointlike coupling of photons to quarks: deep inelastic scattering on a photon or electron target and γγ‐induced jet production at large transverse momentum.

Experiments for the observations of processes involving photon-photon collisions are extremely difficult to perform, because they are crossed-beam experiments which require the highest intensities and the most sensitive detection equipment. For this reason the photon-photon cross sections are at the present time still of little interest to the ...
