摘要
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.Received 17 June 2022Accepted 26 September 2022DOI:https://doi.org/10.1103/PhysRevD.107.052004Published by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license.
