Final State Distortions in Two-particle Correlations

چکیده

Final state interactions in two-particle interferometry is considered for two-particle potentials which are the Coulomb plus “strong” one. For a simple model of the source we provide a full numerical calculation of the correlation function with taking into account two-particle Coulomb interaction plus final state strong interaction. It is found that for small sources (R0 = 1− 4 fm) the contribution from the strong interaction is appreciable and depresses the correlations while for large fireballs (R0 = 7−10 fm) this contribution is small in comparison to the Coulomb one.

Refractive Distortions of Two-Particle Correlations

Using optical model calculations it has recently been shown that refractive phenomena from the collective mean field can significantly alter the sizes inferred from two-pion correlations. We demonstrate that such effects can be accounted for in classical calculations if mean field effects are included.

Effects of Fsi, Cr and Bec at Small Relative Momenta of Particles and W-mass Systematics at Lep

The observation of the enhanced production of like–sign particle pairs by LEP experiments at Z does not insure that the observed correlations owe their origin to Bose-Einstein correlations(BEC). They could, for example, arise from final state interactions(FSI) between pions with small relative momenta. (we recommend not to call BEC and/or Colour Reconnection as ’FSI effects’ as it is generally ...

Three-particle correlation from glasma flux tubes

We compute three particle correlations in the Glasma flux tube model of high energy heavy ion collisions. We obtain a simple geometrical picture of these correlations; when convoluted with final state radial flow, it results in distinct predictions for the near side three particle correlation in central heavy ion collisions.
