We also present preliminary results for the B_{Bd}, B_{Bs}, B_{Bs}/B_{Bd} and \\xi -parameter controlling B^0_-\\bar{B}^0 oscillations in the Standard Model employing the so-called ratio method. Using Nf=2 maximally twisted sea quarks and Osterwalder-Seiler valence quarks we achieve both O(a)-improvement and continuum like renormalization pattern.
