$B_{(s)}\to S$ transitions in the light cone sum rules with the chiral current

Yan-Jun Sun, Zuo-Hong Li, Tao Huang

$B_{(s)}$ semi-leptonic decays to the light scalar meson, $B_{(s)}\to Sl{\bar{\nu }}_l,Sl\bar{l}(l=e,\mu ,\tau )$, are investigated in the QCD light-cone sum rules (LCSR) with chiral cur…
