Charge asymmetries in e\gamma \to eW^+W^-. Hunting for strong   interaction in Higgs sector
  The study of charge asymmetry of W bosons in the process \egam\to eWW can be a tool for discovery of strong interaction in Higgs sector at energies that are lower than it is necessary for observation of resonances caused by this strong interaction.
