Towards the identification of new physics through quark flavour violating processes
AJ Buras, J Girrbach - Reports on Progress in Physics, 2014 - iopscience.iop.org
We outline a systematic strategy that should help in this decade to identify new physics (NP)
beyond the standard model (SM) by means of quark flavour violating processes, and thereby …

Family nonuniversal models with protected flavor-changing interactions
We define a new class of Z′ models with neutral flavor-changing interactions at tree level in
the down-quark sector. They are related in an exact way to elements of the quark mixing …
