Multi-Pion Correlation Effects on Two-Pion Interferometry
A general derivation of the multi-pion correlation function for completely chaotic source is given. Its effects on the pion multiplicity distribution, twopion interferometry are studied. A generalized multi-pion correlation function for a partially coherent source is also discussed.
متن کاملNon-Gaussian Effects in Identical Pion Correlation Function at STAR
Abstract. Preliminary femtoscopic results on identical pions from high statistics data set of Au+Au collisions at √ sNN = 200 GeV taken during the fourth RHIC run are presented. The measured threedimensional correlation function is studied at low relative momenta using the Gaussian parametrization and the Lévy stable parametrization. The latter is expected to better describe the data. As the re...

متن کاملFinite coherent length and multi-pion correlation effects on two-pion interferometry
The effects of multi-pion correlations and finite coherent length on two-pion interferometry are studied. It was shown that as the pion multiplicity and coherent length become larger, the apparent radius and the apparent coherent parameters derived from two-pion interferometry become smaller. The influence of the coherent length on the effective temperature is discussed. PACS number(s): 25.75 D...
متن کاملPion pair production in e + e − annihilation
We present an analysis of the process ee → γ orZ → ππγ, in the kinematical region where √ s, the c.m. energy of the ee pair, is large but much below the Z-pole. The subprocess γ orZ → ππγ can be described by the convolution of the hard scattering coefficient γ orZ → qq̄γ and the general distribution amplitude of two pions qq̄ → ππ. In the case of neutral pion, the production through γ is the domi...
