Title:    Baryon Light-Cone Wave Functions and Properties in the
           Chiral Quark-Soliton Model

Abstract:  Recently, a formalism was developed which allows one to calculate
light-cone wave functions of baryons within the Chiral Quark-Soliton Model. 
This model considers light baryons as valence quarks bound by a relativistic
mean pion field with a non-trivial topology. The non-trivial topology allows 
one to write down without free parameter the whole tower of Fock states for 
all light baryons. We have explicitly computed contributions from the 3-, 5- 
and even 7-quark components to various charges (vector, axial, tensor, 
magnetic moment) and shown that the sea contribution is essential to 
understand static properties of light baryons, as well as relativistic 
effects such as orbital angular momentum.

Moreover, we have obtained a clear signature for a distortion of the baryon 
shape due to the pion field. Many experimental observables are quite well 
reproduced by this ab initio calculation. This allows us to make numerous 
predictions concerning the unmeasured ones (in octet, decuplet and 
antidecuplet).
