Hi @wuctlby ! Thanks for the development. It seems to me the Lc->pK0s might not be turned on when matched. Please check and, if so, add these lines in the other configs

Hi @stefanopolitano, the modification concluded as below:

  • Turn on the matching for Λc -> pK0s
  • Add the decay channel D+ -> K*0(1430) π+ 1.25% into D+ -> K- π+ π+, and set the ratio as 0.05880. At the same time, the D+ -> K- π+ π+ is set to0.44120
    Please let me know if anything needs further modification.
