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…

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…
