Status of the B -> pi K puzzle and its relation to B_s -> phi pi and B_s -> phi rho decays
Lars Hofer, Leonardo Vernazza
Some discrepancies between theory and experiment in the B -> pi K decays suggest the possibility of a new physics contribution with the structure of an electroweak penguin amplitud…

Structure of Infrared Singularities of Gauge-Theory Amplitudes at Three and Four Loops
Valentin Ahrens, Matthias Neubert, Leonardo Vernazza
The infrared divergences of massless n-parton scattering amplitudes can be derived from the anomalous dimension of n-jet operators in soft-collinear effective theory. Up to three-l…
