DESCRIPTION:The Light Cone Distribution Amplitudes (LCDA) with a heavy qua
 rk play an important role in a number of aspects of B decays\, that we wil
 l review. There is a great variety of ansatze or predictions for these LCD
 A in the litterature. We propose to predict them by a relations to the Sha
 pe Function (SF) of B mesons. This is done within a class of covariant qua
 rk models that exhibit Isgur-Wise scaling. The SF parameters can be extrac
 ted from the B->X_s+gamma spectrum and give a prediction for the LCDA. The
  results for the latter are compared with the recent measurements by BaBar
  and with other theoretical approaches.\n\nhttps://indico.ific.uv.es/event
