    Coupled-Channel Analysis of the χc1 (3872) Line Shape with BESIII Data
    (American Physical Society, 2024) Ablikim, M.; Achasov, M.N.; Adlarson ,P.; Çetin, Serkant Ali; Kolcu, Onur Buğra
    We perform a study of the χc1(3872) line shape using the data samples of e+e-→γχc1(3872), χc1(3872)→D0D¯0π0, and π+π-J/ψ collected with the BESIII detector. The effects of the coupled channels and the off-shell D∗0 are included in the parametrization of the line shape. The line shape mass parameter is obtained to be MX=(3871.63±0.13-0.05+0.06) MeV. Two poles are found on the first and second Riemann sheets corresponding to the D∗0D¯0 branch cut. The pole location on the first sheet is much closer to the D∗0D¯0 threshold than the other, and is determined to be 7.04±0.15-0.08+0.07 MeV above the D0D¯0π0 threshold with an imaginary part -0.19±0.08-0.19+0.14 MeV. © 2024 authors.
