BEC of Two Photons and Higgs Physics

It is well understood that the studies of correlations between produced particles, the effects of coherence and chaoticity, an estimation of particle emitting source size play an important role in high energy physics [1]. We mean the investigation of the space-time extension or even squeezing of particle sources via the multiparticle quantum-statistics correlation. We obtain the two-photon correlation function that can provide the space-time information about the Higgs-boson source in thermal environment and we argue that such an investigation could probe the Higgs-boson mass.
