NA49 experiment at CERN-SPS [Lambda production in Pb+Pb at 40 A GeV]

  • The experiment NA49 at the CERN SPS is a large acceptance detector for charmed hadrons. The identification of neutral strange hadrons Lambda and AntiLambda is based on the measurement of their charged decay particles and the reconstruciton of the decay vertex. The charged particles were measured with the 4 time projection chambers (TPC), two of them are situated inside 2 large dipole magnets, the two others are downstream of the magnet. Lambda and AntiLambda baryons have been measured in central Pb+Pb collisions at 40, 80 and 160 GeV/nucleon over a wide range in rapidity (1 - 5) and transverse momentum (0 - 3 GeV/c). Particle yields and spectra will be shown for the different energies. The results will be put into the existing systematics of Lambda-production as a function of beam energy.
