  We show that the study of scalar resonances at various vector boson
scattering processes at the Large Hadron Collider can serve as a useful tool to
distinguish between different extensions of the scalar sector of the Standard
Model. The recent measurement of the Higgs boson properties leaves enough room
for the extended scalar sectors to be relevant for such studies. The shape of
the resonances, being model dependent, can shed light on the viable parameter
space of a number of theoretical models.
