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…

Final State Interactions in the Ds+ --> omega pi+ and Ds+ --> rho0 pi+ Decays

Svjetlana Fajfer, Anita Prapotnik, Paul Singer +1

We investigate the decay mechanisms in the Ds+ --> omega pi+ and Ds+ --> rho0 pi+ transitions. The naive factorization ansatz predicts vanishing amplitude for the Ds+ --> omega pi+…

Charm Radiative Decays with Neutral Mesons D^0 -> K^0(bar) pi^0 gamma, D^0 -> K^0(bar) eta (eta') gamma

Svjetlana Fajfer, Anita Prapotnik, Paul Singer

The radiative decays D^0 -> K^0(bar) P^0 gamma with nonresonant K^0(bar) P^0 (P^0 = pi^0, eta, eta') are considered within the framework which combines heavy quark effective theory…

Cabibbo Allowed D -> K pi gamma Decays

Svjetlana Fajfer, Anita Prapotnik, Paul Singer

The weak radiative Cabibbo allowed decays D^+ -> anti K^0 pi^+ gamma and D^0 -> K^- pi^+ gamma with nonresonant K pi are investigated by relying on the factorization approximation…

Constraints on heavy Z' couplings from ΔS = 2 B^- -> K^- K^- π^+ decay

S. Fajfer, P. Singer

The heavy Z' boson with family nonuniversal couplings can introduce flavour changing effects. Constraints on nondiagonal Z' couplings coming from the μ-e conversion in a muonic ato…
