We study the contribution of the gluino-squark mediated flavor changing process for the CP violation in $bto s$ and $bto d$ transitions facing on recent experimental data. The mass insertion parameters of squarks are constrained by the branching ratios of $bto sgamma $ and $bto dgamma $ decays. In addition, the time dependent CP asymmetries of $B^0to phi K_S$ and $B^0to eta K^0$ decays severely restrict the allowed region of the mass insertion parameter for the $bto s$ transition. By using these constraints with squark and gluino masses of 1.5 TeV, we predict the CP asymmetries of $B_sto phi phi $, $B_sto eta phi $, and $B^0to K^0bar K^0$ decays, as well as the CP asymmetries in $bto sgamma $ and $bto dgamma $ decays. The CP violation in the $B_sto phi phi$ decay is expected to be large owing to the squark flavor mixing, which will be tested at LHCb soon.
We present results of global fits of all relevant experimental data on rare $b to s$ decays. We observe significant tensions between the Standard Model predictions and the data. After critically reviewing the possible sources of theoretical uncertain
$B$ decays proceeding via $bto cell u$ transitions with $ell=e$ or $mu$ are tree-level processes in the Standard Model. They are used to measure the CKM element $V_{cb}$, as such forming an important ingredient in the determination of e.g. the unitar
We investigate the possibility of explaining the enhancement in semileptonic decays of $bar B to D^{(*)} tau bar u$, the anomalies induced by $bto smu^+mu^-$ in $bar Bto (K, K^*, phi)mu^+mu^-$ and violation of lepton universality in $R_K = Br(bar Bt
In the Standard Model (SM), the rare transitions where a bottom quark decays into a strange quark and a pair of light leptons exhibit a potential sensitivity to physics beyond the SM. In addition, the SM embeds Lepton Flavour Universality (LFU), lead
We perform a data-driven analysis of new physics (NP) effects in exclusive $b to s ell^+ell^-$ decays in a model-independent effective theory approach with dimension six operators considering scalar, pseudo-scalar, vector and axial-vector operators w
