Measurements of the properties of Lambda(c)(2595), Lambda(c)(2625), Sigma(c)(2455), and Sigma(c)(2520) baryons

Abstract

We report measurements of the resonance properties of c ð2595Þþ and c ð2625Þþ baryons in their decays to þ c þ as well as c ð2455Þþþ 0 and c ð2520Þþþ 0 baryons in their decays to þ c final states. These measurements are performed using data corresponding to 5:2 fb1 of integrated luminosity from pp collisions at ffiffiffis p ¼ 1:96 TeV, collected with the CDF II detector at the Fermilab Tevatron. Exploiting the largest available charmed baryon sample, we measure masses and decay widths with uncertainties comparable to the world averages for c states, and significantly smaller uncertainties than
