The Impact of a 4th Generation on Mixing and CP Violation in the Charm System

Buras, Andrzej J., Duling, Björn, Feldmann, Thorsten et al.

Understand

We study D0-D0 mixing in the presence of a fourth generation of quarks.

In particular, we calculate the size of the allowed CP violation which is found at the observable level well beyond anything possible with CKM dynamics.
We calculate the semileptonic asymmetry a_SL and the mixing induced CP asymmetry eta_fS_f which are correlated with each other.
We also investigate the correlation of eta_fS_f with a number of prominent observables in other mesonic systems like epsilon'/epsilon, Br(K_L -> pi0 nu nu), Br(K+ -> pi+ nu nu), Br(B_s ->mu+ mu-), Br(B_d -> mu+ mu-) and finally S_psi phi in the B_s system.
