New dense superball packings in three dimensions

We construct a new family of lattice packings for superballs in three dimensions (unit balls for the l(3)(p) norm) with p epsilon (1, 1.58]. We conjecture that the family also exists for p epsilon (1.58, log(2) 3 = 1.5849625 ...]. Like in the densest lattice packing of regular octahedra, each superball in our family of lattice packings has 14 neighbors.
