Search for Doubly Charmed Baryons Xi_cc^+ and Xi_cc^++ in BABAR

TL;DR

This study conducted a search for doubly charmed baryons Xi_cc^+ and Xi_cc^++ in electron-positron collisions at 10.58 GeV using the BABAR detector, but found no evidence of their production.

Contribution

First search for doubly charmed baryons in e+e- collisions at BABAR with specific decay channels analyzed.

Findings

No evidence for doubly charmed baryon production

Set upper limits on production rates

Analyzed multiple decay channels

Abstract

We search for the production of doubly charmed baryons in e^+e^- annihilations at or near a center-of-mass energy of 10.58 GeV, in a data sample with an integrated luminosity of 232 fb^-1 recorded with the BABAR detector at the PEP-II storage ring at the Stanford Linear Accelerator Center. We search for Xi_cc^+ baryons in the final states Lambda_c^+K^-pi^+ and Xi_c^0pi^+, and Xi_cc^++ baryons in the final states Lambda_c^+K^-pi^+pi^+ and Xi_c^0pi^+pi^+. We find no evidence for the production of doubly charmed baryons.
