Abstract
We report on mass and lifetime measurements of several ground state charmed and bottom baryons, −1 pffiffi from pp ̄ collisions at s 1⁄4 1.96 TeV and recorded with the using a data sample corresponding to 9.6 fb Collider Detector at Fermilab. Baryon candidates are reconstructed from data collected with an online event selection designed for the collection of long-lifetime heavy-flavor decay products and a second event selection designed to collect J=ψ → μþμ− candidates. First evidence for the process Ω−b → Ω0cπ− is presented with a significance of 3.3σ. We measure the following baryon masses:File in questo prodotto:
