A bstractMotivated by the recent measurement of the dimuon asymmetry by the DØ collaboration, which could be interpreted as an enhanced decay rate difference in the neutral Bd-meson system, we investigate the possible size of new-physics contributions to ΔΓd. 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
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
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,
Lifetimes and HQE
Kolya Uraltsev was one of the inventors of the Heavy Quark Expansion (HQE), that describes inclusive weak decays of hadrons containing heavy quarks and in particular lifetimes. Besides giving a
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
Flavor phenomenology of the leptoquark singlet-triplet model
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
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


Neutral gauge boson contributions to the dimuon charge asymmetry in B decays
Recently, the DØ Collaboration measured the CP-violating like-sign dimuon charge asymmetry in neutral B decays, finding a 3.2σ difference from the standard-model (SM) prediction. Anon-SM charge
ΔΓd: a forgotten null test of the standard model
The recent measurement of an anomalous like-sign dimuon asymmetry by the D0 collaboration has prompted theoretical speculation on possible sources of physics beyond the standard model that may affect
Mixing asymmetries in B meson systems, the D0 like-sign dimuon asymmetry and generic New Physics
The measurement of a large like-sign dimuon asymmetry $A^b_{SL}$ by the D0 experiment at the Tevatron departs noticeably from Standard Model expectations and it may be interpreted as a hint of
Exclusive Chromomagnetism in heavy-to-light FCNCs
We compute matrix elements of the chromomagnetic operator, often denoted by O 8 , between B/D states and light mesons plus an off-shell photon by employing the method of light-cone sum rules at
New results on B→π,K,η decay form factors from light-cone sum rules
We present an improved calculation of $B\ensuremath{\rightarrow}$ light pseudoscalar form factors from light-cone sum rules, including one-loop radiative corrections to twist-2 and twist-3
CP violation in B{s} mixing from heavy Higgs boson exchange.
It is shown that, for a range of couplings and masses, the heavy neutral states in a two-Higgs doublet model can generate a large charge asymmetry.
Less space for a new family of fermions
We investigate the experimentally allowed parameter space of an extension of the standard model (SM3) by one additional family of fermions. Therefore we extend our previous study of the
Measurement of the semileptonic charge asymmetry in $B^0$ meson mixing with the D0 detector
We present a measurement of the semileptonic mixing asymmetry for B0 mesons, a^d_{sl}, using two independent decay channels: B0 -> mu+D-X, with D- -> K+pi-pi-; and B0 -> mu+D*-X, with D*- -> antiD0
