The Weak Annihilation Form Factors Of Quark-antiquark In B?VV

We make an estimate ofthe weak annihilation form factors for B??? hadronic matrix elements in the light-cone sum rule approach. Forthe scalar quarkoperatorand the pseudoscalar quark operator, the corresponding annihilation form factors are defined in the chiral limit.Then a light-cone sum rule calculation is performed at large space-like region( 02Q(27)) and QCD leading order.The resulting sum rules are analytically continued tothe time-like region(22Bm Q(28)),to obtain the desiredresult.
