      abstract     = {The phenomenon of B$^{0}$ $_{q}$– mixing (q = d, s)
                      provides a sensitive probe for physics beyond the Standard
                      Model (SM). We explore the corresponding space for New
                      Physics left through the current data, having a careful look
                      at analyses of the Unitarity Triangle that are needed for
                      the SM predictions of the B $_{q}$ mixing parameters. In
                      particular, we explore the impact of tensions between
                      inclusive and exclusive determinations of the CKM matrix
                      elements ∣V $_{ub}$∣ and ∣V $_{cb}$∣. Moreover, we
                      focus on the angle γ of the Unitarity Triangle, comparing
                      measurements from B → DK and B → π π, ρ π, ρ ρ
                      decays, where the latter are typically interpreted in terms
                      of the angle α. We discuss various scenarios and present
                      the corresponding state-of-the-art constraints on the New
                      Physics parameters of B$_{q}$ $^{0}$– mixing. We point out
                      that these results have an interesting application in the
                      analysis of rare decays, allowing us to minimise the impact
                      of CKM parameters in the search for New Physics. In view of
                      the high-precision era, we make future projections.
                      Interestingly, we find that for the extraction of the New
                      Physics parameters in the B $_{d}$ system the determination
                      of the apex of the Unitarity Triangle results in a key
                      limiting factor. By contrast, the corresponding impact is
                      negligible for the B $_{s}$ system, making it a promising
                      candidate to reveal sources of New Physics.},
