Abstract: We study the $$D_s^+\rightarrow \pi ^+(a_0(980)^0\rightarrow )\pi ^0\eta $$ D s + → π + ( a 0 ( 980 ) 0 → ) π 0 η , $$\pi ^0(a_0(980)^+\rightarrow )\pi ^+\eta $$ π 0… read more here.

Abstract: In this paper we calculate the $$\bar{B}_s \rightarrow f_0(980)$$ form factors from light-cone sum rules with B meson DAs. With adopting the quark–antiquark configuration of light scalar mesons, the high twist two-particle and the three-particle… read more here.
