Rare leptonic processes induced by massless dark photon

open access: yesPhysics Letters B, 2023
We introduce a dark photon considering a U(1) gauge extension of the standard model in particle physics. Provided that the extra U(1) symmetry is unbroken, the dark photon is massless and has no coupling to the standard electromagnetic current.

Photon-photon interaction in axial channeling [PDF]

open access: yesPhysical Review A, 1994
We investigate the possibility that high-energy photons are channeled, when passing through an oriented single crystal, due to Delbrück scattering. For this purpose the exact electron propagator for the single-string model is constructed. Starting from a separation of variables, we solve the Dirac equation for a cylindrical electrostatic potential. The

PHOTON-PHOTON INTERACTION IN STRUCTURED QED VACUUM [PDF]

open access: yesInternational Journal of Modern Physics: Conference Series, 2012
In spatially structured strong laser fields, quantum electrodynamical vacuum behaves like a nonlinear Kerr medium with modulated third-order susceptibility where new coherent nonlinear effects arise due to modulation. We consider the enhancement of vacuum polarization and magnetization via coherent spatial vacuum effects in the photon-photon ...

Photon-photon interaction and the Schwinger process [PDF]

open access: yesPhysical Review D, 2013
We consider the tunneling processes induced by two-particle collisions. The result derived by the termal bath approach is reproduced by the classical configurations. The Coulomb and Yukawa corrections for the rate of the process are computed.

Photon interactions with superconducting topological defects

open access: yesPhysics Letters B, 2021
Using a toy model for the interactions between a defect-forming field and the photon field where the photon becomes massive in the defect core (motivated by recent work on defects in the 2HDM), we study the impact on photon propagation in the background ...

PHOTON – POMERON COUPLING IN HADRONIC INTERACTIONS [PDF]

open access: yesمجلة جامعة الانبار للعلوم الصرفة, 2012
Pomeron coupling to photons has been analyzed. As the pomeron assumed to couple to hadrons through their constituent quarks and since the photon has no constituent quarks it's coupling to the pomeron is not well known.

Hadronic photon-photon interactions at high energies [PDF]

open access: yesPhysical Review D, 1996
Photon-photon collisions are investigated in the framework of the two-component Dual Parton Model. The model is shown to agree well to hadron production data from hadron-hadron and photon-hadron collisions. The multiparticle production in hadron-hadron, photon-hadron and photon-photon collisions as predicted by the model is compared. Strong differences

PHOTON-PHOTON INTERACTIONS [PDF]

open access: yesNuclear Physics A, 1981
Abstract A brief summary of the present status of photon-photon interactions is presented. Stress is placed on the use of two-photon collisions to test present ideas on the quark constituents of hadrons and on the theory of strong interactions.

Quantum nondemolition detection of a propagating microwave photon [PDF]

open access: yes, 2013
The ability to nondestructively detect the presence of a single, traveling photon has been a long-standing goal in optics, with applications in quantum information and measurement.

Enhanced photon routing beyond the blockade limit via linear optics

open access: yesPhysical Review Research, 2023
Directing indistinguishable photons from one input port into separate output ports is a fundamental operation in quantum information processing. The simplest scheme for achieving routing beyond random chance uses the photon blockade effect of a two-level
