"Evidence for ${Z}_{c}^{\ifmmode\pm\else\textpm\fi{}}(3900)$ in semi-inclusive decays of $b$-flavored hadrons." <i>Physical Review D,</i> 98, no. 5 (2018) American Physical Society: https://doi.org/10.1103/PhysRevD.98.052010.https://hdl.handle.net/1911/104987We present evidence for the exotic charged charmoniumlike state Z±c(3900) decaying to J/ψπ± in semi-inclusive weak decays of b-flavored hadrons. The signal is correlated with a parent J/ψπ+π− system in the invariant-mass range 4.2–4.7 GeV that would include the exotic structure Y(4260). The study is based on 10.4 fb−1 of p¯p collision data collected by the D0 experiment at the Fermilab Tevatron collider.engPublished by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license.
