Observation of Two Resonances in the Λb0 π± Systems and Precise Measurement of Σb± and Σb∗± Properties

Academic Article

Abstract

  • © 2019 CERN. The first observation of two structures consistent with resonances in the final states Λb0π- and Λb0π+ is reported using samples of pp collision data collected by the LHCb experiment at s=7 and 8 TeV, corresponding to an integrated luminosity of 3 fb-1. The ground states Σb± and Σb∗± are also confirmed and their masses and widths are precisely measured.
