Abstract 



Let H be a bialgebra and D an Hbimodule algebra and Hbicomodule coalgebra. We find sufficient conditions on D for the LRsmash product algebra and coalgebra structures on D circle times H to form a bialgebra (in this case we say that (H, D) is an LRadmissible pair), called LRsmash biproduct. The Radford biproduct is a particular case, and so is, up to isomorphism, a double biproduct with trivial pairing. We construct a prebraided monoidal category LR(H), whose objects are Hbimodules Hbicomodules M endowed with leftleft and rightright YetterDrinfeld module as well as leftright and rightleft Long module structures over H, with the property that, if (H, D) is an LRadmissible pair, the D is a bialgebra in LR(H).
