Gluonic Penguins in from QCD Light-Cone Sum Rules
Alexander Khodjamirian, Thomas Mannel, Piotr Urban
The hadronic matrix element of the chromomagnetic dipole operator (gluonic penguin) is calculated using the QCD light-cone sum rule approach. The resulting sum r…

On the hierarchy of neutrino masses
M. Jezabek, P. Urban
We present a model of neutrino masses combining the seesaw mechanism and strong Dirac mass hierarchy and at the same time exhibiting a significantly reduced hierarchy at the level…

A hidden hierarchy of neutrino masses
M. Jezabek, P. Urban
The Dirac masses of neutrinos can exhibit a strong hierarchy even if the Majorana masses of the right-handed neutrinos are degenerate and the hierarchy of the mass scales governing…
