Resumen

Utilizando 7,33 fb-1 de datos de colisión e+e- recopilados por el detector BESIII a energías c.m. entre 4,128 GeV y 4,226 GeV, observamos por primera vez el decaimiento Ds±→ωπ±η con una significancia estadística de 7,6σ. La fracción de ramificación medida de este decaimiento es del (0,54 ± 0,12 ± 0,04) %, donde la primera incertidumbre es estadística y la segunda, sistemática.
