Kaon production and kaon to pion ratio in Au+Au collisions at root(NN)-N-s=130 GeV

Original language description

Mid-rapidity transverse mass spectra and multiplicity densities of charged and neutral kaons are reported for Au + Au collisions at root(s)NN = 130 GeV at RHIC. The spectra are exponential in transverse mass, with an inverse slope of about 280 MeV in central collisions. The multiplicity densities for these particles scale with the negative hadron pseudo-rapidity density. The charged kaon to pion ratios are K+/pi(-) = 0.161 +/- 0.002(stat) +/-0.024(syst) and K-/pi(-) = 0. 146 +/- 0.002(stat) +/-0.022(syst) for the most central collisions. The K+/pi(-) ratio is lower than the same ratio observed at the SPS while the K-/pi(-) is higher than the SPS result. The ratios are enhanced by about 50% relative to p + p and 0 + p collision data at similar energies

Produkce kaonů a poměr kaonů k pionům ve srážkách Au+Au při root(s_NN)=130 GeV

Czech description

Střední rapidita spektra příčných hmotností a multiplicity hustot nabitých a neutrálních kaonů pro srážky na RHIC jsou oznámeny. Multiplicity hustot pro tyto částice škálují s hustotou negativní hadronové pseudorapidity. Poměr K+/pi- je nižší nez pozorovaný na SPS, zatímco K-/pí- je vyšší než výsledek SPS
