We suggest that top physics can be studied at the LHCb experiment, and that top production could be observed. Furthermore, we demonstrate that LHCb may be able to measure a t - bar t production rate asymmetry.

We analyse a simple Standard Model (SM) extension with only two new light fields: a scalar partner of the top (stop) with mass above m_t, and a light neutral fermion with mass of a few GeV, coupled to SM quarks via a Yukawa interaction. We show that such model can lead to a significant enhancement of the forward-backward asymmetry in t tbar production at the Tevatron via the additional t tbar pairs produced from (stop anti-stop) decays.

We investigate anomalous t W d_j interactions as a possible source of new effects in B_{d,s} - bar B_{d,s} oscillations. We show how such interactions can explain the anomalous CP violation in B_s sector.
