    generalized the table of mesons-as-irreps from Spin(3,1)Spin(3,1) to Pin +(3,1)Pin^+(3,1), to bring out the pseudo-scalar nature of the pion, and the pseudo-vector nature of the ρ\rho-meson and the ω\omega-meson

    have expanded the representation-theoretic table of mesons (here), now including also the sigma-meson (in parenthesis) and then the strange mesons.

    I consistently had an inconsistency in the tables regarding vector/pseudovector mesons. Fixing now.
