Using 9.9 fb-1 of e+e- collision data collected by the BESIII detector at center-of-mass energies between 4.15 and 4.30 GeV, we search for the processes e+e-→γX(3872) with X(3872)→π0χc0 and X(3872)→ππχc0.

Combined with the BESIII measurement of X(3872)→π0χc1, we also set an upper limit of B(X(3872)→π0χc0)B(X(3872)→π0χc1)<4.5

Abstract
Using 9.9 fb-1 of e+e- collision data collected by the BESIII detector at center-of-mass energies between 4.15 and 4.30 GeV, we search for the processes e+e-→γX(3872) with X(3872)→π0χc0 and X(3872)→ππχc0. We set upper limits (at 90% C.L.) of B(X(3872)→π0χc0)B(X(3872)→π+π-J/ψ)<3.6, B(X(3872)→π+π-χc0)B(X(3872)→π+π-J/ψ)<0.56, and B(X(3872)→π0π0χc0)B(X(3872)→π+π-J/ψ)<1.7. Combined with the BESIII measurement of X(3872)→π0χc1, we also set an upper limit of B(X(3872)→π0χc0)B(X(3872)→π0χc1)<4.5File in questo prodotto:
