A measurement of polarization in inclusive production by of 340 GeV/c in C and Cu targets
We have measured the polarization of hyperons produced inclusively by a beam of 340 GeV/c momentum in nuclear targets. From a sample of 880000 identified decays, polarizations were determined in the range 0 < x F < 0.9 and GeV/c. The polarization w.r.t. the production normal is negative for 0.3. At fixed values of x F , its magnitude increases with p t to maximum values which reach about 20% at large x F .
