New Physics in Γ s 12 : ( s̄b ) ( τ̄ τ ) Operators

  title={New Physics in $\Gamma$ s 12 : ( s̄b ) ( $\tau$̄ $\tau$ ) Operators},
  author={Christoph Bobeth and U. Haisch},
Measurements performed at the Tevatron of both the like-sign dimuon charge asymmetry inBd,s-meson samples and the mixing-induced CP asymmetry inBs → J/ψφ depart from their standard model (SM) predictions. This could be an indication for new CP phases in ∆B = 2 transitions, preferentially in Bs–B̄s mixing. The experimental situation, however, remained inconclusive, as it favored values of the element Γ12 of the decay matrix in the Bs-meson system that are notably different from the SM…

CP asymmetry in the angular distributions of τ → KSπντ decays. Part II. General effective field theory analysis
In this work, we proceed to study the CP asymmetry in the angular distributions of τ → K S πν τ decays within a general effective field theory framework including four-fermion operators up to
$B$ Flavour Anomalies: 2021 Theoretical Status Report
At the present time, there are discrepancies with the predictions of the SM in several observables involving b→ s`+`− and b→ c`ν̄` decays. These are the B flavour anomalies. In this review, we
Nonminimal 331 model for lepton flavor universality violation in b→sℓℓ decays
The 331 models constitute an extension of the Standard Model (SM) obtained by enlarging the SM gauge group SU(3)C×SU(2)L×U(1)Y to the group SU(3)C×SU(3)L×U(1)X. We investigate how a nonminimal 331
Searching for t → c(u)h with dipole moments
A bstractA discovery of flavour-changing Higgs-boson decays would constitute an undeniable signal of new physics. We derive model-independent constraints on the tch and tuh couplings that arise from
Lepton flavour violating top decays at the LHC
We consider lepton-flavour violating decays of the top quark, mediated by 4-fermion operators. We compile constraints on a complete set of SU(3) $$\times $$× U(1)-invariant operators, arising from
Search for the decays $B_s^0\to\tau^+\tau^-$ and $B^0\to\tau^+\tau^-$
A search for the rare decays Bs0→τ+τ- and B0→τ+τ- is performed using proton–proton collision data collected with the LHCb detector. The data sample corresponds to an integrated luminosity of 3  fb-1
New physics in $\Delta \Gamma_d$
We analyze the possibility of having new physics effects in the decay rate difference, $\Delta \Gamma_d$, of neutral $B_d$ mesons. Three different sources of enhancement are considered, CKM unitarity
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
