Abstract
The nucleon polarizabilities alpha(E) and beta(M) are studied in the context of the perturbative chiral quark model. We demonstrate that meson cloud effects are sufficient to explain the electric polarizability of nucleon. Contributions of excite quark states to the paramagnetic polarizability are dominant and cancel the diamagnetic polarizability arising from the chiral field. The obtained results are compared to data and other theoretical predictions.
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. No sentence in this record was written by a model.

The nucleon polarizabilities have been studied via a number of theoretical approaches based on dispersion relations [ref] , phenomenological Lagrangians [ref] , constituent quark models [ref] , chiral-soliton type of models [ref] and lattice QCD using the external electromagnetic field method in quenched [ref] and unquenched approximation [ref] .
