A measurement of the transverse polarization of Λ-hyperons produced in inelastic pN -reactions at 450 GeV proton energy
نویسندگان
چکیده
A study of the polarization of Λ hyperons produced in inelastic pN reactions induced by the 450 GeV proton beam from the CERN SPS has been performed with the NA48 detector. The Λ hyperons were detected at a fixed angle of 4.2 mrad in the momentum range from 50 GeV/c to 200 GeV/c. The polarization changes from −0.053 ± 0.034 to −0.298 ± 0.074 for a transverse momentum range of the Λ between 0.28 GeV/c and 0.86 GeV/c. The Λ polarization is consistent with zero. 266 V.

The results on transverse mass spectra of Λ hyperons produced in all inelastic p+p and p+p interactions in the energy range √ sNN = 3.6 − 1800 GeV are compiled and analyzed. The energy dependence of the mean transverse mass and the inverse slope parameter of the spectra is presented and discussed. These results should be used as a reference in the study of Λ hyperon production in nuclear collis...

Spin transfer to Λ + c hyperons in polarized proton collisions at RHIC The analysis[1] of helicity transfer to Λ + c in polarized proton collisions is extended to the proton helicity correlations with the Λ + c transverse polarization in the production plane (parameter D LS). The available spin transfer observ-ables for the collisions of two longitudinally polarized protons are evaluated. It is...
متن کاملLongitudinal Polarization of Λ and Λ̄ Hyperons in Lepton-Nucleon Deep-Inelastic Scattering
We consider models for the spin transfer to Λ and Λ̄ hyperons produced in lepton-nucleon deep-inelastic scattering. We make predictions for longitudinal Λ and Λ̄ spin transfer for the COMPASS experiment and for HERA, and for the spin transfer to Λ hyperons produced at JLAB. We show that a measurement of Λ polarization in the COMPASS experiment in a region of x that has not previously been explore...

Preliminary results for the longitudinal polarization of Λ and ¯ Λ hyperons in longitudinally polarized proton-proton collisions at √ s = 200 GeV are presented. The Λ(¯ Λ) candidates are reconstructed at mid-rapidity (|η| < 1) with the time projection chamber of the STAR experiment at RHIC, using 0.5 pb −1 collected in 2003 and 2004 with beam polarizations of up to 45%. Their mean longitudinal ...
