Abstract: We have chosen the reactions Ds+→π+π0a0(980)(f0(980)) investigating the isospin violating channel Ds+→π+π0f0(980). The reaction was chosen because by varying the π0a0(980)(f0(980)) invariant mass one goes through the peak of a triangle singularity emerging from Ds+→π+K¯*K,… read more here.
