The lightcone distribution amplitudes of the pseudoscalar and scalar light mesons are (re)analyzed in the pure perturbative QCD approach to the meson transition form factors, as well as, in the combined analysis of several hard exclusive processes. The informations obtained from the confrontation with the experimental data, the open questions and the limitations of the approach will be discussed.

The Bmeson lightcone distribution amplitudes (LCDAs) are matrix elements of operators involving one heavyquark field sandwiched between the Bmeson state and the vacuum. In this talk, I will present the recent developments regarding the evolution of highertwist LCDAs as well as the renormalization of the leadingtwist LCDA at the twoloop order. In particular, I will discuss how the renormalization group equations (RGEs) of highertwist operators are completely integrable from spin chain models. I will also explain how to calculate the evolution kernel of the leadingtwist LCDA using conformal symmetry.

The gravitational form factors for a hadron, the form factors for the hadron matrix element of the QCD energymomentum tensor, not only describe the coupling of the hadron with a graviton, but also serve as unique quantities for describing the shape inside the hadron reflecting dynamics of quarks and gluons, such as the internal shear forces acting on the quarks/gluons and their pressure distributions. The gravitational form factors are also relevant to understanding the origin of hadron mass. We consider the quark/gluon contributions to the gravitational form factors for a pseudoscalar meson, and also for the nucleon. We derive the relations satisfied by the gravitational form factors as direct consequences of the symmetries and the equations of motion in QCD, and connections to the generalized (offforward) parton distributions. Our results show the connections between the gravitational form factors and the highertwist quarkgluon correlation effects inside the hadrons. Furthermore, we are able to constrain the twistfour gravitational form factors by the trace anomalies in QCD, and derive the corresponding relations at three loop. We mention properties of the gravitational form factors for a heavy meson in the heavy quark limit, and also prospects to calculate the gravitational form factors using the LCSRs.

Calculation of electromagnetic nucleon form factor in perturbative QCD is an old and seamingly overdiscussed story, but there is still a shadow hanging over that straightforward calculation. Namely, there is factor of 2 discrepancy among results obtained by different groups. The usual suspects were normalizations of the nucleon wave function. Different explanations were offered but without conclusive answer and the final statement was that there are simply two different normalizations which both are equally reasonable. Consequently, the problem appeared: two different physical results. The unpleasant situation was circumvented by taking ratio between various amplitudes and everyone was happy. But no one should be. Years passed, we stumbled upon the problem, decided to reopen the case and definitely solve the mystery. The outcome was surprising and, of course, the answer was where no one expected it.
