Single-particle space-momentum angle distribution effect on two-pion HBT correlation with Coulomb interaction

Planar Two-particle Coulomb Interaction: Classical and Quantum Aspects

The classical and quantum aspects of planar Coulomb interactions have been studied in detail. In the classical scenario, Action Angle Variables are introduced to handle relativistic corrections, in the scheme of time-independent perturbation theory. Complications arising due to the logarithmic nature of the potential are pointed out. In the quantum case, harmonic oscillator approximations are c...

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.

Two-Pion Wave Functions with Non-zero Total Momentum

We calculate the two-pion wave function for the I = 2 S-wave two-pion system with a finite scattering momentum and estimate the interaction range between two pions. It allows us to examine the validity of the necessary condition for the finite-volume method for the scattering phase shift. A calculation is carried out with a plaquette gauge action for gluons and a clover-improved Wilson action f...

Beam Energy Evolution of HBT Systematics at the AGS

We present preliminary results of the first π interferometry (HBT) excitation function at intermediate AGS energies. The beam energy evolution of the correlations' dependence on m T , centrality, and emission angle with respect to the reaction plane are discussed. Comparisons with predictions of the RQMD cascade model are made. Two-particle intensity interferometry (HBT) measurements have long ...
