Simple Scenario of Photons Emission from Anti Charm–Gluon Interaction using QCD Theory

open access: yesJournal of Kufa-Physics, 2023
  In this work, the chromodynamics (QCD) theory was used to investigate the photon rate which was produced in interactions of anti-charm with gluon.

Experimental results on photon-photon interactions at adone

open access: yesPhysics Letters B, 1979
Abstract Experimental results for the reactions e+e− → e+e− + X are presented for X = e+e−, μ+μ−, π+π− , ″'. A tagging technique has been used to detect final electrons and positrons. A QED test is performed and an upper limit of 20 keV is derived for the partial width Γ(η′ → γγ).

Optical signal processing via two-photon absorption in a semiconductor microcavity for the next generation of high-speed optical communications network [PDF]

open access: yes, 2006
Due to the introduction of new broadband services, individual line data rates are expected to exceed 100 Gb/s in the near future. To operate at these high speeds, new optical signal processing techniques will have to be developed.

Measurement of the Second-Order Polarizability of Silver Nanoparticles With Reference-Free Hyper-Rayleigh Scattering for Entangled Photon Pair Interaction

open access: yesIEEE Photonics Journal, 2022
Two-photon interactions of entangled-photon pairs with metallic nanoparticles (NPs) can be enhanced by localized surface-plasmon resonance. Recently, we have described how the properties of this quantum light-matter interaction can be deduced from ...

Tagging photon interactions at the LHC [PDF]

open access: yes, 2008
Photon interactions at the LHC result in striking final states with much lower hadronic activity in the central detectors than for pp interactions. In addition, the elastic exchange of a photon leads to a proton scattered at almost zero-degree angle ...

Photon-Photon Interaction in Glueball Production [PDF]

open access: yesInternational Journal of Modern Physics: Conference Series, 2017
In the last years many exotic states have been identified in several colliders around the world. One of the exotic states provided in QCD is the glueball. Using a non-relativistic gluon bound-state model, we compute [Formula: see text], where [Formula: see text] is a pseudoscalar, tensor, or scalar digluon.

Probing flavor-changing interactions in photon-photon collisions [PDF]

open access: yesPhysical Review D, 1998
We examine the subprocess $γγ\to t\bar{c}+\bar{t}c$ at electron-positron colliders in the two-Higgs-doublet model with flavor-changing scalar couplings, where all the one-loop contribuions are considered, and the results are applicable to the whole mass range of the weakly coupled Higgs bosons.

Photon - Photon Interaction

open access: yes, 2018
The famous 1927 Solvay Conference was considered a turning point in the world of Physics. The scientific realists like Albert Einstein had lost and the instrumentalists like Niels Bohr had won the fundamental conflict. Since then Physics has followed the path of the instrumentalists in which Quantum Physics has been determined by the concept of ...

Constraints on CP-Odd ALP Couplings from EDM Limits of Fermions

open access: yesParticles, 2020
We discuss constraints on soft CP-violating couplings of axion-like particles with photon and fermions by using data on electric dipole moments of standard model particles.
