Radiative and isospin-violating decays of Ds mesons in the hadrogenesis conjecture

Understand

The masses and decays of the scalar D_{s0}^*(2317) and axial-vector D_{s1}^*(2460) charmed strange mesons are calculated consistently in the hadrogenesis conjecture.

• These mesons decay either strongly into the isospin-violating pi^0 D_s and pi^0 D_s^* channels or electromagnetically.
• They are generated by coupled-channel dynamics based on the leading order chiral Lagrangian.
• The effect of chiral corrections to chiral order Q_\chi^2 is investigated.
