We construct a family of q deformations of E ( 2 ) group for nonzero complex parameters | q | < 1 as locally compact braided quantum groups over the circle group 𝕋 viewed as a quasitriangular quantum group with respect to the unitary R -matrix R ( m , n ) : = ( q / q ̄ ) m n for all m , n ∈ ℤ . For real 0 < | q | < 1 , the deformation coincides with Woronowicz’s E q ( 2 ) groups. As an application, we study the braided analogue of the contraction procedure between SU q ( 2 ) and E q ( 2 ) groups in the spirit of Woronowicz’s quantum analogue of the classic Inönü–Wigner group contraction. Consequently, we obtain the bosonization of braided E q ( 2 ) groups by contracting U q ( 2 ) groups.
