Photon–photon scattering: a tutorial [PDF]

open access: yesCanadian Journal of Physics, 2012
Long-established results for low-energy photon–photon scattering, γγ → γγ, have recently been questioned. We analyze that claim and demonstrate that it is inconsistent with experience. We demonstrate that the mistake originates from an erroneous manipulation of divergent integrals and discuss the connection with another recent claim about the Higgs ...

On the Remarkable Features of the Lower Limits of Charge and the Radiated Energy of Antennas as Predicted by Classical Electrodynamics

open access: yesAtmosphere, 2016
Electromagnetic energy radiated by antennas working in both the frequency domain and time domain is studied as a function of the charge associated with the current in the antenna.

HIGH ENERGY PHOTON-PHOTON AND ELECTRON-PHOTON COLLISIONS [PDF]

open access: yesInternational Journal of Modern Physics A, 1998
The advent of a next linear e±e- collider and back-scatterd laser beams will allow the study of a vast array of high energy processes of the Standard Model through the fusion of real and virtual photons and other gauge bosons. As examples, I discuss virtual photon scattering γ*γ*→X in the region dominated by BFKL hard Pomeron exchange and report the ...

Kerr-Nonlinearity-Triggered Nonclassicality of Magnons in a Photon-Magnon Coupling System

open access: yesPhotonics, 2022
Hybrid quantum systems have attracted much attention due to the fact that they combine the advantages of different physical subsystems. Cavity QED (cavity quantum electrodynamics) with magnons is a hybrid quantum systems that combines a YIG (Yttrium Iron

Photons as Probes of Gluon Saturation in Dilute + Dense Collisions

open access: yesProceedings, 2019
We use the Color Glass Condensate (CGC) effective field theory (EFT) to calculate inclusive photon production to leading order q g → q γ , (LO), and next-to leading order g g → q q ¯ γ (NLO) at LHC energies.

Universal dependence of the total number albedo of photons on the mean number of photon scatterings [PDF]

open access: yesNuclear Technology and Radiation Protection, 2011
This paper presents the results of research on photon reflection from plane targets based on Monte Carlo simulations performed by the MCNP code. Five materials (water, concrete, aluminum, iron, and copper) are examined in the area of initial photon ...

Monitoring Neutron Radiation in Extreme Gamma/X-Ray Radiation Fields

open access: yesSensors, 2020
The monitoring of neutron radiation in extreme high ≈1014 (#/cm2-s) neutron/photon fields and at extremely-low (≈10−3 #/cm2-s) levels poses daunting challenges—important in fields spanning nuclear energy, special nuclear material ...

Coupled-Channel Analysis of the Process γγπ0π0

open access: yesParticles, 2022
We study the process γγ→π0π0 involving the principal mechanisms, the structure of its cross section and the role of individual isoscalar-tensor resonances in the saturation of its energy spectrum.
