Various precision measurements with B mesons from ATLAS are presented. They include studies of CP violation in $B^0_s\to J/\psi\phi$ decay, $B_c^+$ meson decay properties and measurement of B0 meson lifetime, along with average decay width $\Gamma_d$ and $\Gamma_d/\Gamma_s$ ratio.

Lepton Flavor Universality (LFU) is a fundamental principle in the Standard Model (SM) of particle physics, stating that the interactions of different generations of leptons with the weak force should be identical. However, experimental observations in the last decade have hinted at potential violations of LFU by comparing the ratios of branching fractions of semileptonic $b \to c \ell \nu$...

The Belle and Belle$~$II experiments have collected a 1.1$~$ab$^{-1}$ sample of $e^+ e^-\to B\bar{B}$ collisions at the $\Upsilon(4S)$ resonance. These data, with low particle multiplicity, constrained initial state kinematics and excellent lepton identification, are an ideal environment to study lepton-flavour universality in semileptonic decays of the $B$ meson. We present results on the...

The Belle and Belle$~$II experiments have collected a 1.1$~$ab$^{-1}$ sample of $e^+ e^-\to B\bar{B}$ collisions at the $\Upsilon(4S)$ resonance. The study of hadronic $B$ decays in these data allows the precise measurement of absolute branching fractions and angular distributions of the decay products. These measurements provide tests of QCD and allow the generation of more realistic...

Motivated by the interplay between the LEFT and SMEFT operators at the electroweak scale, we study the interrelation among the transitions $b \to c \ell \nu_{\ell}$, $b \to s \nu _\ell \nu _\ell$ and $b \to s\ell \ell$ ($\ell = e, \mu, \tau$). We explore this correlation within the context of six - SMEFT operators: $\mathcal{Q}_{\ell q}^{(3)}$, $\mathcal{Q}_{\ell ed q}$, $\mathcal{Q}_{\ell e...
