The nonperturbative effects in the Sudakov quark form factor are considered in the Wilson loop formalism. The renormalization properties of the Wilson loops with cusp singularities are studied with account of perturbative and nonperturbative contributions, where the latter are considered within the framework of the instanton liquid model. For the integration path corresponding to this form factor – the angle with infinite sides, the explicit expression for the vacuum expectation value of the… CONTINUE READING
