Description
| - Představujeme měření korelačních funkcí proton-Lambda, proton-antiLambda, antiproton-Lambda a antiproton-antiLambda provedené experimentem STAR na RHIC v centrálních srážkách Au-Au při (sNN)=200GeV. Velikost zdroje protonů a Lambda částic byla získána z korelačních funkcí proton-Lambda a antiproton-antiLambda. Změřená velikost je menší než velikost pionového zdroje změřeného taktéž experimentem STAR. Toto pozorování může být důsledkem kolektivní expanze systému. Korelační funkce pro Proton-antiLambda a antiproton-Lambda byly změřeny poprvé a vykazují silnou antikorelaci. Aby bylo možné zreprodukovat daný výsledek, je nutné při interakci ve finálním stavu uvažovat anihilační kanály a/nebo negativní hodnotou reálné části spinově průměrované rozptylové délky. (cs)
- We report on p-Lambda, p-Lambda bar, p bar-Lambda and p bar-Lambda bar correlation functions constructed in central Au-Au collisions at (sNN)=200GeV by the STAR experiment at RHIC. The proton and lambda source size is inferred from the p-Lambda and p bar-Lambda bar correlation functions. They are found to be smaller than the pion source size also measured by the STAR detector. This could be a consequence of the collision fireball's collective expansion. The p-Lambda bar and p bar-Lambda correlations, which are measured for the first time, exhibit a large anti-correlation. Annihilation channels and/or a negative real part of the spin-averaged scattering length must be included in the final-state interactions calculation to reproduce the measured correlation function.
