Abstract: We consider a system of two interacting particles with like but unequalcharges in a magnetic field in the planar geometry. We construct a completebasis of states compatible with both the axial symmetry and magnetictranslations. The basis is obtained using a canonical transformation thatgenerates effective quasiparticles with modified interactions. We establish aconnection of this transformation with the SU2 algebra and make use of theSU2 Baker-Campbell-Hausdorff formulas for evaluating the interaction matrixelements. We calculate analytically the eigenenergies of the problem Haldanepseudopotentials in the first few Landau levels for a relatively wide class ofinteraction potentials.
