摘要：

We show that the recent anomalies in b -> sl(+)l(-) transitions observed by the LHCb collaboration can be accommodated within string motivated models with a low mass Z' gauge boson. Such Z' gauge boson can be obtained in compactifications with a low string scale. We consider a class of intersecting D-brane models in which different families of quarks and leptons are simultaneously realized at different D-brane intersections. The explanation of b -> sl(+)l(-) anomalies via a stringy Z' sets important restrictions on these viable D-brane constructions.
