Description
We study the ππ spectrum in Υ(3S)→Υ(1S)ππ decay using the most general matrix element in the lowest order in the pion momentum expansion. We find a good fit to the ππ spectrum, and predict various angular distributions of decay products of Υ(3S), all of which can be tested by current experiments
