Resumo: 

I discuss a combined explanation of charged- and neutral-current
B-physics anomalies which assume the presence of a light sterile neutrino
state. Two simplified scenario are considered: a scalar and a vector
leptoquark model. While at present both models are compatible with direct
LHC searches and low-energy flavor measurements, already with 300/fb of
data the LHC will be able to completely test parameter space.
I will then discuss the cosmological constraints on the sterile neutrino
state and the conditions under which it can be a Dark Matter candidate.
