WE have carried out three searches of pentaquarks at CDF. First,
we will present the search for a neutral pentaquark Theta_c which decays
into D* and proton. This search has been performed using 240 pb-1 data
samples of a displaced-two-track trigger. Second, we will present the
search for a charged pentaquark Theta+ which decays into K0(s) and proton.
This search has been performed using data samples of a minimum bias trigger
and a jet trigger. Third, we will present the search for a doubly-charged
pentaquark which decays into Xi and pi. This search has been performed
using 220 pb-1 data samples of a displaced two-track trigger and a jet
trigger.
