Light Flavor Hadron Production as a Function of Multiplicity in pp Collisions at {formula}= 7 TeV Measured with ALICE

摘要

82.1 Introduction In recent measurements, several collective features similar to Pb-Pb collisions have been observed in high multiplicity pp and p-Pb collisions. Two-particle correlation studies indicate that there are flow-like effects in high-multiplicity pp and p-Pb collisions systems analogous to Pb-Pb collisions [1-4]. Particle ratio (e.g. A/K~0_s) measurements in p-Pb collisions show similar features to Pb-Pb collisions [5]. In order to understand the origin of these intriguing features, a comprehensive study of identified particle production in pp collisions is needed.
