I was reading some material on Particle physics and I came across the sentence:

pseudoscalar D and B meson states and the corresponding vector resonances D* and B*.

What are vector resonances?

Source: Phenomenology of heavy meson Chiral Lagrangians by Casalbuoni,Bartolomeo,Gatto,Feruglio and Nardulli. 7th page from the introduction.

Pseudoscalar and vector are terms that indicate the total spin and parity of the resonance. Pseudoscalar particles have spin 0 and parity -1, while vector particles have spin 1 and parity -1.

The Particle Data Review lists your particles as:

  • $D^\pm\qquad\qquad\qquad\quad 0^-$
  • $D^0\qquad\qquad\qquad\quad 0^-$
  • $D^*(2007)^0\qquad \qquad 1^-$
  • $D^*(2010)^\pm\qquad\qquad 1^-$
  • $B^\pm\qquad\qquad\qquad\quad 0^-$
  • $B^0\qquad\qquad\qquad\quad 0^-$
  • $B^*\qquad\qquad\qquad\quad 1^-$
