QCD sum rule analysis of the subleading Isgur-Wise form factors tau(1)(nu center dot nu ') and tau(2)(nu center dot nu ') for B -> D(1)l(nu)over-bar and B -> D(2)(*)l(nu)over-bar - art. no. 054010

We present a QCD sum rule calculation of the Isgur-Wise form factor tau(1)( upsilon.upsilon') and tau(2)(upsilon.upsilon') for the semileptonic decays B --> D-1(2420)l<(nu)over bar> and B --> D-2* (2460)l<(nu)over bar> in the framework of heavy quark effective theory. These two universal functions, a ssociated with the matching of the weak currents in QCD onto those in the e ffective theory, appear at the order 1/m(Q) in the heavy quark expansion of meson weak decay form factors.
