  A search is presented for exotic processes that result in final states
containing jets including at least one b jet, sizable missing transverse
momentum, and a pair of leptons with the same electric charge. Using a sample
of 14.3 fb^-1 of pp collisions at sqrt(s) =8 TeV recorded by the ATLAS detector
at the Large Hadron Collider, no significant excess of events over the
background expectation is observed. This observation is interpreted as
constraining several signal hypotheses beyond the Standard Model and limits are
set at 95% confidence level on relevant parameters of the signal hypotheses.
