Hydrodynamic Parameterization of NA 44 Data on Kaon and Pion Correlations and Spectra

چکیده
An analytically calculable model [1] has been proposed recently for the simultaneous description of particle spectra and correlations, which is able to explain in a natural manner the m t scaling of the radius parameters of the Bose–Einstein correlation functions. We present here preliminary results on fitting this model to data sampled by NA44 collaboration in central S + Pb reactions at CERN SPS, which indicate that both pions and kaons freeze-out at a surprisingly low temperature of T ≃ 108 MeV.

Non - identical particle correlation analysis as a probe of transverse flow
Non-identical two particle correlation functions probe asymmetries between the average space-time emission points of different particle species. The system collective expansion would produce such asymmetry because massive particles, such as protons, are on average more pushed towards the edge of the system, than lighter ones, i.e. pions. Measuring pion-kaon, pion-proton and kaon-proton correlat...
متن کاملKaon production cross sections from baryon-baryon interactions
In a one-pion plus one-kaon exchange model, we calculate the kaon production cross sections in nucleon-nucleon, nucleon-delta and delta-delta interactions. We find that this model describes reasonably well the experimental data on kaon production in the proton-proton interaction. Near the kaon production threshold, the cross section obtained from this model is smaller than that from the linear ...

To determine the position of quasi-bound state, the triton kinetic energy spectrum in the resonant capture of at rest in is calculated by a coupled-channel procedure. An analysis of theoretical spectra to experimental data yielded the mass and width of , respectively, and, where a possible population of and a small p-orbit capture contribution are taken into account. The calculations show t...

The antikaon production cross section from nucleon-nucleon reactions near threshold is studied in a meson exchange model. We include both pion and kaon exchange, but neglect the interference between the amplitudes. In case of pion exchange the antikaon production cross section can be expressed in terms of the antikaon production cross section from a pion-nucleon interaction, which we take from ...
متن کاملLow Freeze-out Temperature and High Collective Velocities in Relativistic Heavy-Ion Collisions
On the basis of a nine-parameter expanding source model that includes special relativity, quantum statistics, resonance decays, and freeze-out on a realistic hypersurface in spacetime, we analyze in detail invariant π+, π, K+, and K one-particle multiplicity distributions and π+ and K+ two-particle correlations in nearly central collisions of Si + Au at plab/A = 14.6 GeV/c. By considering separ...
