We report on the first Belle II measurements of branching fractions and CP-violating charge asymmetries in charmless $B$ decays. We use 34.6 fb$^{-1}$ from electron-positron collisions collected in 2019 and 2020 at the $\Upsilon(4S)$…

We study the charmless two-body decays of $b$-baryons $(\Lambda_b$, $\Xi_b^-$, $\Xi_b^0)$. We find that ${\cal B}(\Xi_b^-\to \Lambda \rho^-)=(2.08^{+0.69}_{-0.51})\times 10^{-6}$ and ${\cal B}(\Xi_b^0\to \Sigma^+…
Charmless B hadrons decays offer rich opportunities to test the Standard Model. CP violation in charmless charged two-body and three-body B decays provides ways to measure the CKM angle $\gamma$ and to search for New Physics. Also,…
Rare B meson decays are an excellent probe for beyond the Standard Model physics. Two very sensitive processes are the b -> s mu^+ mu^- and B0 -> mu^+ mu^- decays. We report recent results at a center of mass energy of sqrt(s) = 1.96 TeV…

The Tevatron, with $p\bar{p}$ collisions at $\sqrt{s}=$1.96 TeV, can produce all flavors of $B$ hadrons and allows for unprecedented studies in the $B$ physics sector. These range from measurements of $B$ hadron properties to searches of…
Our analysis suggests that the charmless yield in B decays is enhanced over traditional estimates. The c c.bar pair produced in b to c c.bar transitions may be seen significantly as light hadrons due to non-perturbative effects. Existing…
