${{\mathit \Lambda}_{{c}}{(2860)}^{+}}$ MASS

INSPIRE   PDGID:

B178M

VALUE (MeV) DOCUMENT ID TECN  COMMENT $2856.1$ ${}^{+2.0}_{-1.7}$ $\pm0.5$ ${}^{+1.1}_{-5.6}$ 1 AAIJ 2017 S LHCB in ${{\mathit \Lambda}_{{b}}^{0}}$ $\rightarrow$ ${{\mathit D}^{0}}{{\mathit p}}{{\mathit \pi}^{-}}$ 1  The third AAIJ 2017S uncertainty comes from modeling the resonant shape of the nearby ${{\mathit \Lambda}_{{c}}{(2880)}^{+}}$ and the background (non-resonant) amplitudes.
