The hidden strangeness mechanism in Ds^+ -> omega pi^+ and Ds^+ -> rho^0 pi^+ decays
Svjetlana Fajfer, Anita Prapotnik, Paul Singer +1
We study possible contributions to the Ds^+ -> omega pi^+ and Ds^+ -> rho^0 pi^+ decay amplitudes. The Ds^+ -> omega pi^+ decay amplitude vanishes when the naive factorization is u…
New-Physics scenarios in decays of the B_c meson
S. Fajfer, J. Kamenik, P. Singer
The transition is extremely small in the standard model, proceeding only via box diagrams. Such decays are thus an appropriate ground for searching new…
On the mass differences between the scalar and pseudoscalar heavy-light mesons
Damir Becirevic, Svjetlana Fajfer, Sasa Prelovsek
We discuss the recent experimental observation which suggested that the mass difference between the scalar and pseudoscalar heavy-light mesons is larger for the non-strange states…
CP violation in the partial width asymmetries for B^- -> pi^+ pi^- K^- and B^- -> K^+ K^- K^- decays
Svjetlana Fajfer, Tri-Nang Pham, Anita Prapotnik
We investigate a possibility of observing CP asymmetries in the partial widths for the decays B^- -> pi^+ pi^- K^- and B^- -> K^+ K^- K^- produced by the interference of the non-re…
The B^- -> phi phi K^- decay rate with phi phi invariant mass below charm treshold
Svjetlana Fajfer, Tri Nang Pham, Anita Prapotnik
We investigate the decay mechanism in the B^- -> phi phi K^- decay with the phi phi invariant mass below the charm threshold and in the neighborhood of the eta_c invariant mass reg…
