Open Problems (the so called "wishlist")

1. Calculation of transversal decay constans from lattice QCD light-pseudoscalar mesons. Two calculalations from quenched lattice-QCD can be found in the literature (hep-lat/0301020) (hep-lat/0306006) . There exist various determinations from QCD sum rules
   
   
2. Calculation of higher twist matrix elements from lattice-QCD. For light pseudoscalars defintion of higher twist matrix elements and results from QCD sum rules can be found in (hep-ph/0603063) . For light vector mesons defintions and results are given in (hep-ph/9802299) . Of particular interest in the case of TDCP-asymmetry for B -> K* gamma (hep-ph/0609037) are f_K*^A and f_K*^V as defined in Eq 2.24 and 2.25. Those matrix elements are of twist-3 and do not mix with lower twist.
   
   
3. Calculation of baryon DA normalizations (defintions) . For references concerning QCD sum rules determinations of those quantities see the full talk (Baryon DA /A.Lenz) .
   
   
4. Two-loop evolution kernel for rho_perp. c.f. (DA-models/P.Ball) . It turns out that this has already been achieved (hep-ph/0008005)
   
   
5. Systematic mass corrections to DA amplitudes. Twist-4 corrections are known to NLO accuracy in the conformal expansion for G-even contributions. The reference for vector meson is (hep-ph/9810475l)
   
   
6. Evolution equations for B-meson DA \phi^B and \phi_bqg c.f. (B-meson DA appl./T.Feldmann) .
