Measurement of the Lambda(b) polarization and angular parameters in Lambda(b) -> J/psi Lambda decays from pp collisions at root s=7 and 8 TeV

Measurement of the Lambda(b) polarization and angular parameters in Lambda(b) -> J/psi Lambda decays from pp collisions at root s=7 and 8 TeV

An analysis of the bottom baryon decay Λb → J=ψð→ μþμ−ÞΛð→ pπ−Þ is performed to measure the Λb polarization and three angular parameters in data from pp collisions at ffiffi s p ¼ 7 and 8 TeV, collected by the CMS experiment at the Large Hadron Collider. The Λb polarization is measured to be 0.0...
