Triangle singularity enhancing isospin violation in Ds+→π+π0f0(980)$D_s^ + \to {\pi ^ + }{\pi ^0}{f_0}(980)$ and B¯s0→J/ψπ0f0(980)$\overline B _s^0 \to J/\psi {\pi ^0}{f_0}(980)$ decays

Triangle singularity enhancing isospin violation in Ds+→π+π0f0(980)$D_s^ + \to {\pi ^ + }{\pi ^0}{f_0}(980)$ and B¯s0→J/ψπ0f0(980)$\overline B _s^0 \to J/\psi {\pi ^0}{f_0}(980)$ decays

We investigate isospin violation in the B¯s0→J/ψπ0a0(980)(f0(980))$\overline B _s^0 \to J/\psi {\pi ^0}{a_0}(980)({f_0}(980))$ and Ds+→π+π0a0(980)(f0(980))$D_s^ + \to {\pi ^ + }{\pi ^0}{a_0}(980)({f_0}(980))$ reactions, which proceed via a triangle mechanism. We show that the mechanism develops a s...
