Abstract: The role of the triangle mechanism in the decay process B0→J/ψ K0f0→J/ψ K0π+π- and B0 J/ψ K0a0→J/ψ K0 π0η is probed. In these process, the triangle singularity appears from the decay of B0 into J/ψΦK0… read more here.

Abstract: We investigate the characteristics of $\sigma$, $f_{0}(980)$, and $a_{0}(980)$ with the formalism of chiral unitary approach. With the dynamical generation of them, we make a further study of their properties by evaluating the couplings, the… read more here.

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.

DOI: 10.1103/physrevd.99.074017
Abstract: We predict that the $a_0^0(980)$-$f_0(980)$ mixing would lead to large CP violation. We calculate the localized direct CP asymmetry in the decays $B^\pm \to f_0(980) [a_0^0(980)] \pi^\pm \to \pi^+ \pi^- \pi^\pm $ via the $a_0^0(980)$-$f_0(980)$… read more here.
