Abstract |
A study of resonant structures in B+ -> D*(DK+)-D-+/--K--/+ and B+ -> D*(DK+)-D-+/--K--/+ decays is performed, using proton-proton collision data at center-of-mass energies of root s = 7, 8, and 13 TeV recorded by the LHCb experiment, corresponding to an integrated luminosity of 9 fb(-1). A simultaneous amplitude fit is performed to the two channels with contributions from resonances decaying to D*D-+/-(+) and D*D-+/-(-) states linked by C parity. This procedure allows the C parities of resonances in the D*D-+/-(-/+) mass spectra to be determined. Four charmonium or charmoniumlike states are observed decaying into D*D-+/-(-/+): eta(c)(3945), h(c)(4000), chi(c1)(4010), and h(c)(4300), with quantum numbers J(PC) equal to 0(-+), 1(+-), 1(+-), and 1(+-), respectively. At least three of these states have not been observed previously. In addition, the existence of the T-(c) over bar(s) over bar0*(2870)(0) and T-(c) over bar(s) over bar1*(2900)(0) resonances in the D-K+ mass spectrum, already observed in the B+ -> D+D-K+ decay, is confirmed in a different production channel. |
