Descrição
From a sample of 848 <math>\pm</math> 44 <math>D_s^+ \to \pi^- \pi^+ \pi^+</math> decays, we find <math>\Gamma(D_s^+ \to \pi^- \pi^+ \pi^+) / \Gamma(D_s^+ \to \phi \pi^+)=0.245 \pm 0.028^{+0.019}_{-0.012}</math>. Using a Dalitz plot analysis of this three body decay, we find significant contributions from the channels <math>\rho^0(770)\pi^+\!\,</math>, <math>\rho^0(1450)\pi^+, f_0(980)\pi^+\!\,</math>, <math>f_2(1270)\pi^+\!\,</math>, and <math>f_0(1370)\pi^+\!\,</math>. We also present the values obtained for masses and widths of the resonances <math>f_0(980)\!\,</math> and <math>f_0(1370)\!\,</math>.
