AB Two-particle angular correlations were measuredin pp collisions at√s = 7 TeV for pions, kaons, protons,and lambdas, for all particle/anti-particle combinationsin the pair. Data for mesons exhibit an expected peak dominatedby effects associated with mini-jets and are well reproducedby general purposeMonte Carlo generators. However,for baryon–baryon and anti-baryon–anti-baryon pairs, whereboth particles have the same baryon number, a near-side anticorrelationstructure is observed instead of a peak. This effectis interpreted in the context of baryon production mechanismsin the fragmentation process. It currently presents achallenge to Monte Carlo models and its origin remains anopen question.
