In particular, we perform model-independent studies of non-standard effects associated to the dimension-six current-current operators ( \overline{d}p )( \overline{p} ′b) with p, p′ = u, c as well as ( \overline{d}p )( \overline{\tau… Charming new B-physics • Physics Journal of High Energy Physics • 2020 Abstract We give a comprehensive account of the flavour physics of Beyond-Standard-Model (BSM) effects in b → c$$ \overline{c}$$c ¯ cs transitions, considering the full set of 20 four-quark Model-independent bounds on new physics effects in non-leptonic tree-level decays of B-mesons • Physics • 2019 We present a considerably improved analysis of model-independent bounds on new physics effects in non-leptonic tree-level decays of B-mesons. Our main finding is that contributions of about$\pm 0.1
$B$-mixing in and beyond the Standard model
We review the status of mixing of neutral $B$-mesons, including a discussion of the current precision of Standard Model (SM) predictions as well as the space that is left for effects of new physics.
CP violation in the $B_s^0$ system

Experimental and theoretical studies of CP violation in the Bs0 system are reviewed. Updated predictions for the mixing parameters of the Bs0 mesons expected in the standard model (SM) are given,

Status of B-mixing in the standard model and beyond
The theoretical methods underlying predictions of mixing quantities ΔMq, and ΔΓq are well understood nowadays. Currently the uncertainties are dominated by nonperturbative matrix elements of local

In recent years, experiments revealed intriguing hints for new physics (NP) in semi-leptonic B decays. Both in charged current processes, involving b → cτν transitions, and in the neutral currents b
Charming New Physics in Beautiful Processes?
In this thesis we study quark flavour physics and in particular observables relating to $B$ meson mixing and lifetimes. Meson mixing arises due to the nature of the weak interaction, and leads to
New physics effects in tree-level decays and the precision in the determination of the quark mixing angle γ
• Physics

We critically review the assumption that no new physics is acting in tree-level B-meson decays and study the consequences for the ultimate precision in the direct determination of the
