Hanbury-Brown and Twiss Intensity Correlations of Parabosons

TL;DR

This paper investigates how intensity correlation measurements can identify parabosons, revealing distinctive signals that differentiate them from bosons through analysis of zero-time-interval correlations in specific quantum states.

Contribution

It introduces a diagonal P-representation for parabosonic fields in even and odd coherent states and analyzes their intensity correlations, highlighting unique signatures of parabosons.

Findings

Intensity correlations reveal clear signals for parabosons.

The second-order correlation factor varies with the mean number of parabosons.

Correlation ratios approach 2/p as paraboson number decreases.

Abstract

This paper shows that in intensity correlation measurements there will be clear and unambiguous signals that new-physics particles are, or aren't, parabosons. For a parabosonic field in a dominant single-mode, there is a diagonal P-representation in the "even and odd coherent states" basis. It is used to analyze zero-time-interval intensity correlations of parabosons in a maximum-entropic state. As the mean number of parabosons decreases, there is a monotonic reduction to (2/p) of the constant bosonic ``factor of two'' proportionality of the second-order versus the squared first-order intensity correlation function.
