By creating these two channels together with a D (0) in B-0 decay and letting them interact as coupled channels, we obtain a structure around their thresholds, short of producing a bound state, which leads to a peak in the D-S(+) Pi(-)mass distribution in the B-0 -> (DDS+)-D-0 Pi(-)decay. We conclude that the interaction between the D*K* and D (*) (s)rho is essential to produce the cusp structure that we associate to the recently seen Tcs(2900), and that its experimental width is mainly due to the decay width of the rho meson. The peak obtained together with a smooth background reproduces fairly well the experimental mass distribution observed in the B (0)-> (DDS+)-D-0 Pi(-) decay.", optnote="WOS:000989395900006", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=5568), last updated on Mon, 10 Jul 2023 07:03:02 +0000", issn="2470-0010", doi="10.1103/PhysRevD.107.056015", opturl="https://arxiv.org/abs/2211.01302", opturl="https://doi.org/10.1103/PhysRevD.107.056015", language="English" }
