Abstract
The source of theoretical uncertainty in the extraction of sin 2beta from the measurement of the golden channel Bd -> J/psi K0 is briefly reviewed. An updated estimate of this uncertainty based on SU(3) flavour symmetry and the measurement of the decay Bd -> J/psi pi0 is also presented.
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. No sentence in this record was written by a model.

Extending furthermore the symmetry group from $U$-spin (used in [ref] ) to full $SU(3)$ allows to relate a sufficiently large number of decay modes (the full set of $B→J/ψP$ modes, with $B∈{B_u,B_d,B_s}$ and $P∈{π^+,π^0,K^+,K^0,K̅^0}$) to determine the $SU(3)$ breaking parameters as well as the penguin pollution ones from the fit, using mild assumptions which are mostly testable with data [ref] .

Comparing with [ref] the second and the third values seem to be conservative and realizeable in nature[More precise data might shrink further the allowed range for penguin contributions.]. $δ_s^peng, SM + δ_s^peng, NP = 10^∘$ corresponds to large penguin contributions (see however [ref] , where such a possibility is even not excluded within the standard model), while $δ_s^peng, SM + δ_s^peng, NP = 0^∘$ corresponds to the hypothetical case that standard model penguins and new physics penguins cancel exactly. $β_s^SM$ and $ϕ_s^SM$ are fixed to their standard model values given Eq.([ref]) and Eq.([ref]).

Given this fact, and the impressive experimental precision the flavour factories and the Tevatron have reached already, and the LHC and future Super Flavour Factories (SFF) are about to achieve, subleading contributions should be taken into account [ref] .

The standard analysis of the unitarity triangle involves a simultaneous fit to several quantities: $ε_K$, $ΔM_B_d$, $ΔM_B_s$, time–dependent $CP$ asymmetry in $B→J/ψK_s$ ($S_ψK = sin(2β)$, where $β$ is the phase of $V_td^*$),[A discussion of penguin pollution in $S_ψK$ can be found in Ref. [ref] ; see also Refs. [ref] .] direct $CP$ asymmetries in $B→D^(*) K^(*)$ ($γ$ is the phase of $V_ub^*$) time dependent $CP$ asymmetries in $B→(ππ, ρρ, ρπ)$ ($α= π-β-γ$), $BR (B→τν)$, $|V_ub|$ and $|V_cb|$ (from both inclusive and exclusive $b→(u,c)ℓν$ with $ℓ= e,μ$).
