Query: Forward-backward asymmetry of $B\to K_J l^+l^-$ decays in SM and new
  physics models   We report on our studies of $B\to K_Jl^+l^-$ in the standard model and
several new physics variations, with $K_J$ denoting a kaonic resoanance. In
terms of helicity amplitudes, we derive a compact form for the full angular
distributions, and use them to calculate the branching ratios, forward-backward
asymmetries and polarizations. We have updated the constraints on effective
Wilson coefficients and/or free parameters in these new physics scenarios by
making use of the $B\to K^*l^+l^-$ and $b\to s l^+l^-$ experimental data. Their
impact on $B\to K_J^*l^+l^-$ is subsequently explored and in particular the
zero-crossing point for forward-backward asymmetry in new physics scenarios can
sizably deviate from the standard model.
