High Transverse Momentum Xi Baryon Correlations in p+p Collisions at   s^(1/2)=200 GeV
  Angular correlations between produced high pT Xi baryons and unidentified charged and neutral particles are observed in high-tower-triggered (on a large electromagnetic energy deposit) s^(1/2)=200 GeV p+p collisions. This trigger favors events with higher average multiplicity than those in minimum bias. These events are likely to contain jets. The average multiplicity of a high-tower triggered event is similar to that of a minimum bias event containing a Xi, which implies that Xi baryons are likely to be produced in jets. Xi mean pT is higher in the triggered data then in the minimum bias sample.
