Abstract

Double-differential yields of Xi (1530)(0) and (Xi) over bar (1530)(0) resonances produced in p+p interactions were measured at a laboratory beam momentum of 158 GeV/c. This measurement is the first of its kind in p+p interactions below LHC energies. It was performed at the CERN SPS by the NA61/SHINE collaboration. Double-differential distributions in rapidity and transverse momentum were obtained from a sample of 26 x 10(6) inelastic events. The spectra are extrapolated to full phase space resulting in mean multiplicity of Xi (1530)(0) (6.73 +/- 0.25 +/- 0.67) x 10(-4) and (Xi) over bar (1530)(0) (2.71 +/- 0.18 +/- 0.18) x 10(-4). The rapidity and transverse momentum spectra and mean multiplicities were compared to predictions of string-hadronic and statistical model calculations.
