Anomalous enhancement of a penguin hadronic matrix element in B->K eta'
J. -M. Gerard, E. Kou
We estimate the density matrix element for the pi^0, eta and eta' production from the vacuum in the large-N_c limit. As a consequence, we find that the QCD axial anomaly leads to h…

Is Vtb=1 ?
J. Alwall, R. Frederix, J. -M. Gerard +6
The strongest constraint on Vtb presently comes from the 3 x 3 unitarity of the CKM matrix, which fixes Vtb to be very close to one. If the unitarity is relaxed, current informatio…

Tracking down penguins at the poles
Jean-Marc Gerard, Christopher Smith, Stephanie Trine
QCD penguins are responsible for about 2/3 of the Delta I=1/2 rule in K to pi pi decays, as inferred from a combined analysis of K to pi pi and KL to gamma gamma. Further tests bas…
