Strange particle production at RHIC in a single-freeze-out model
Wojciech Broniowski, Wojciech Florkowski
Strange particle ratios and pT-spectra are calculated in a thermal model with single freeze-out, previously used successfully to describe non-strange particle production at RHIC. T…
Geometric relation between centrality and the impact parameter in relativistic heavy-ion collisions
W. Broniowski, W. Florkowski
We show, under general assumptions which are well satisfied in relativistic heavy-ion collisions, that the geometric relation of centrality c to the impact parameter b, namely c ~…
Boost-invariant particle production in transport equations
Katarzyna Bajan, Wojciech Florkowski
The boost-invariant tunneling of particles along the hyperbolas of constant invariant time, tau^2 = t^2-z^2, is included in the transport equations describing formation of the quar…
Description of the RHIC p_T-spectra in a thermal model with expansion
Wojciech Broniowski, Wojciech Florkowski
The assumption of simultaneous chemical and thermal freeze-outs of the hadron gas leads to a surprisingly accurate, albeit entirely conventional, explanation of the recently-measur…
Thermal analysis of particle ratios and p_T spectra at RHIC
Wojciech Florkowski, Wojciech Broniowski, Mariusz Michalec
The thermal model of particle production is used to analyze the particle ratios and the p_T spectra measured recently at RHIC. Our fit of the particle ratios yields the temperature…
Scaling of hadron masses and widths in thermal models for ultra-relativistic heavy-ion collisions
Mariusz Michalec, Wojciech Florkowski, Wojciech Broniowski
By means of a simple rescaling, modifications of hadron masses and widths are incorporated into the thermal analysis of particle ratios in ultra-relativistic heavy-ion collisions.…
