$B_{(s)}$ to Light Axial Vector Meson Form Factors via LCSR in HQEFT with Applications to Semileptonic Decays

Ya-Bing Zuo, Ming-Ge Li, Shi-Yu Liang +2

In the present work, the form factors of $B_{(s)}$ to light P-wave axial vector mesons are calculated via the light cone sum rules (LCSR) in the framework of heavy quark effective…
