Questions concerning the Bose-Einstein (BEC) and Fermi-Dirac (FDC) correlations of hadrons produced in $e^+e^-$ collisions are discussed. Among them the emitter dimension $r$ as a function of $\sqrt{s_{ee}}$ and the hadron mass, the…
We consider composite bosons (cobosons) comprised of two elementary particles, fermions or bosons, in an entangled state. First, we show that the effective number of cobosons implies the level of correlation between the two constituent…

Particles are either bosons or fermions, which obey Bose-Einstein (BE) or Fermi-Dirac statistics, respectively. In the hadronization process the effects of the former kind are the most important ones, since mesons are the most common…
Most boson emitting sources contain a core of finite dimensions surrounded by a large halo, due to long-lived resonances like $\omega,\eta,\eta',K^{0}$ etc. When the Bose-Einstein correlation (BEC) function of the core can be determined we…
