Rare Decays of D Mesons

Svjetlana Fajfer

We analyze the dominant decay mechanisms in the radiative decays D -> V gamma, D -> P(V) l+ l-, D -> gamma gamma, D -> l+ l- gamma, and we discuss possible chances to observe the e…

The Search for New Physics in D^0 --> gamma gamma Decay

S. Fajfer, P. Singer, J. Zupan

We present main results of the investigation of the rare decay mode D^0 -->gamma gamma, in which the long distance contributions are expected to be dominant. Using the Heavy Quark…

FCNC transition $c \to u γ$ in $B_{c} \to B_{u}^{*} γ$ decay

S. Fajfer, S. Prelovsek, P. Singer

We propose the $B_{c} \to B_{u}^{*} γ$ decay as the most suitable probe for the flavour changing neutral transition $c \to u γ$ . We estimate the short and long distance contributions to this…

Semileptonic and nonleptonic two-body charmed meson decays in an effective model

B. Bajc, S. Fajfer, R. J. Oakes +1

We analyze charm meson semileptonic $D \to V l ν_{l}$ and $D \to P l ν_{l}$ and nonleptonic $D \to P V$ , $D \to P P$ and $D \to V V$ decays within a model which combines the heavy quark e…

The role of resonances in rare K decays

S. Fajfer

The decays $K \to π l^{+} l^{-}$ , $K \to π γ γ$ and $K \to π ν ν ˉ$ are investigated using the higher order terms of the chiral perturbation theory. The counterterms induced by str…

Charm meson radiative decays

B. Bajc, S. Fajfer, R. J. Oakes

Combining heavy quark effective theory and the chiral Lagrangian approach we investigate D meson radiative decays. First, we reanalyse $D^{*} \to D γ$ decays using heavy qu…
