Research paper thumbnail of Lambda0 Polarization as Function of Target Density

Ijmpa, 2005

Λ0 polarization (P) depends on xf and pt; it depends also on the density of the target material: ... more Λ0 polarization (P) depends on xf and pt; it depends also on the density of the target material: P(xf, pt, ρ) = (κ0/(λ0 + ρ/ρw))xfpt, with κ0 = -0.423±0.065 (GeV/c)-1 and λ0 = 1.191±0.200 in the range 0<pt<1.2 GeV. Here ρ is the target material density and ρw is the Tungsten density. From this equation, it follows that Λ0 polarization is reduced by target density.
