We study the scattering of low-energy tensor multiplet particles against a Bogomol'nyi-Prasad-Sommerfield (BPS)-saturated cosmic string. We show that the corresponding S matrix is largely determined by symmetry considerations. We then apply a specific supersymmetric model of (2,0) theory and calculate the scattering amplitudes to lowest nontrivial order in perturbation theory. Our results are valid as long as the energy of the incoming particle is much lower than the square root of the string tension. The calculation involves the quantization of a (2,0) tensor multiplet and the derivation of an effective action describing the low-energy particles in the presence of a nearly BPS-saturated string.
