This is an announcement for the paper "Dominated bilinear forms and 2-homogeneous polynomials" by G. Botelho, D. Pellegrino and P. Rueda. Abstract: The main goal of this note is to establish a connection between the cotype of the Banach space X and the parameters r for which every 2-homogeneous polynomial on X is r-dominated.
