Abstract

We present a search for the decay X(3872)→π+π-π0 in the (772±11)×106 ϒ(4S)→BB¯ data sample collected at the Belle detector, where the X(3872) is produced in B±→K±X(3872) and B0→KS0X(3872) decays. We do not observe a signal, and set 90% credible upper limits for two different models of the decay processes: if the decay products are distributed uniformly in phase space, B(X(3872)→π+π-π0)<1.3%, and if M(π+π-) is concentrated near the mass of the D0D¯0 pair in the process X(3872)→D0D¯∗0+c.c.→D0D¯0π0→π+π-π0, B(X(3872)→π+π-π0)<1.2×10-3.
