Prompt K_short production in pp collisions at sqrt(s)=0.9 TeV

LHCb Collaboration, Aaij, R., Beteta, C. Abellan et al.

Understand

The production of K_short mesons in pp collisions at a centre-of-mass energy of 0.9 TeV is studied with the LHCb detector at the Large Hadron Collider.

  • The luminosity of the analysed sample is determined using a novel technique, involving measurements of the beam currents, sizes and positions, and is found to be 6.8 +/- 1.0 microbarn^-1.
  • The differential prompt K_short production cross-section is measured as a function of the K_short transverse momentum and rapidity in the region 0 < pT < 1.6 GeV/c and 2.5 < y < 4.0.
  • The data are found to be in reasonable agreement with previous measurements and generator expectations.
