Based on experimental data by the Belle Collaboration, we present a phenomenological analysis of the angular distributions in pi(-) -> K-S pi(-) nu(tau) decay. Our study shows that the angular analysis could lead to some interesting observables, and the future experimental investigation of these observables might be very helpful in revealing the nature of the scalar components of the decay. New physics contributions from the two-Higgs-doublet model to this decay have also been examined. DOI: 10.1103/PhysRevD.87.073016
