[show abstract][hide abstract] ABSTRACT: Published measurements of semi-inclusive Λ production in p–Au collisions at the AGS are used to estimate the yields of singly strange hadrons in nucleus–nucleus (A–A) collisions. Results of a described extrapolation technique are shown and compared to measurements of K+ production in Si–Al, Si–Au, and Au–Au collisions at the AGS and net Λ production in S–S, S–Ag, Pb–Pb, and inclusive p–A collisions at the SPS. The extrapolations can account for more than 75% of the measured strange particle yields in all of the studied systems except for very central Au + Au collisions at the AGS where RQMD comparisons suggest large re-scattering contributions.
[show abstract][hide abstract] ABSTRACT: In this paper we report on a Monte-Carlo program, SToF, developed to evaluate the performance of scintillator-based Time-of-Flight (TOF) detectors. This program has been used in the design of the TOF system for the PHENIX experiment at RHIC. The program was used to evaluate the intrinsic time-of-flight resolution of various scintillator and light-guide geometries, and the results of these simulations are presented here. The simulation results agree extremely well with measured pulse-height and time distributions with one adjustable parameter. These results, thus, explain also the reduced quantities, such as the position dependence of the time resolution, etc, implying that SToF will be generally useful for estimating the performance of TOF detectors.
