Searches for Pentaquark Baryons at BaBar

PDF Version Also Available for Download.

Description

This paper presents the results of inclusive searches for the strange pentaquark states {Theta}{sup +}(1540), {Xi}{sub 5}{sup --}(1860) and {Xi}{sub 5}(1860){sup 0} as well as the anti-charm pentaquark state {Theta}{sub c}(3099){sup 0} in a dataset of 123.4 fb{sup -1} collected on and 40MeV below the {Upsilon}(4S) resonance by the BABAR detector at the e{sup +}e{sup -} PEP-II storage rings. No evidence for the pentaquark states is found and upper limits on the rate of {Theta}{sup +}(1540) and {Xi}{sub 5}{sup --}(1860) production in e{sup +}e{sup -} annihilation are obtained.
