Preliminary Results on Prompt \(\Xi^+/\Xi^-\) Production ratio in \(pp\) Collisions at \(\sqrt{s} = 7~\text{TeV}\)

Nguyen Mau Chung, Nguyen Thi Dung, Tran Minh Tam


The ratio of prompt \(\Xi^+/\Xi^-\) production has been investigated from a limitedsample of data registered by the LHCb experiment at the CERN Large Hadron Colliderin 2010. This ratio has been determined in the rapidity region \(1.9 \leq y \leq 4.9\) covered bythe LHCb detector. The determination of anti-hyperons to hyperons production ratio willallow to study the transport of baryon number from pp collisions to final state hadrons andto constrain and tune Monte Carlo models.
