Azimuthal correlations in photon-photon collisions.
Using the general helicity formula for γγ collisions, we are showing that it should be possible to determine a number of independent “structure functions”, i.e. linear combinations of elements of the two-photon helicity tensor, through azimuthal correlations in two-body or quasi two-body reactions induced by the photon-photon interaction, provided certain experimental conditions are satisfied. ...
متن کاملHeavy-quark Correlations in Direct Photon-photon Collisions
In two-photon collisions at LEP2 and a future ee linear collider heavy quarks (mainly charm) will be pair-produced rather copiously. The production via direct and resolved photons can be distinguished experimentally via a remnant-jet tag. We study correlations of the heavy quarks at next-to-leading order in QCD in the direct channel, which is free from phenomenological parton densities in the p...

Fritzsche1 1University of Kassel, Kassel, Germany; 2KINR, 03680 Kyiv, Ukraine; 3MPI–K, Heidelberg, Germany; 4GSI, Darmstadt, Germany The two–photon decay of (hydrogenlike) atoms has been studied intensively both, by theory and experiment. However, while most investigations in the past have dealt with neutral hydrogen or low–Z ions, recent in...
متن کاملOne-Dimensional Waveguide Coupled to Multiple Qubits: Photon-Photon Correlations
For a one-dimensional (1D) waveguide coupled to two or three qubits, we show that the photon-photon correlations have a wide variety of behavior, with structure that depends sensitively on the frequency and on the qubit-qubit separation L. We study the correlations by calculating the second-order correlation function g2(t) in which the interference among the photons multiply scattered from the ...
متن کاملThermal noise and correlations in photon detection.
The standard expressions for the noise that is due to photon fluctuations in thermal background radiation typically apply only for a single detector and are often strictly valid only for single-mode illumination. I describe a technique for rigorously calculating thermal photon noise, which allows for arbitrary numbers of optical inputs and detectors, multiple-mode illumination, and both interna...
