Abstract	A search is presented using events with b-jets, sizable missing transverse energy and total transverse momentum from leptons and jets ($H_\text{T}$), and at least two leptons with the same charge in the final state. The Standard Model processes that produce final states of this sort are relatively rare, so the SM backgrounds for this search are low. Several signal models are explored, which could produce an enhanced production rate for final states with same charge dileptons. The signal models explored here are Vector-Like Quark $B$, $T$, and $T_{5/3}$ via pair production, and several 4-top ($t\overline{t}t\overline{t}$) signatures: Standard Model production, contact interaction, and a model with two Universal Extra Dimension under the real projective plane geometry.
