Charm measurements allow for testing the Standard Model in a way complementary to measurements in b-quark sector. LHCb experiment, with its large data sample and excellent performance, provides sensitivity approaching the Standard Model predictions for rare charm decays. In this talk, recent LHCb results on rare decays of charm hadrons will be presented.
The Belle II experiment has collected a 424fb$^{-1}$ sample of $e^{+}e^{-}$ collision data at center-of-mass energies near the resonances $\Upsilon(nS)$. This sample contains 389 million $e^{+}e^{-} \to \tau^{+}\tau^{-}$ events, which we use for precision tests of the standard model. In this talk, we focused on the measurements of the tau-lepton mass and
tests of Lepton Flavor Universality...
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 and constrained initial state kinematics, are an ideal environment to search for rare $B$ meson decays proceeding via electroweak and radiative penguin processes. Results include those of the decay $B^+\to...
Highly suppressed (Rare) $b$-quark processes provide an excellent probe into heavy New Physics (NP) scenarios in conjunction with stringent tests of the Standard Model (SM). Rare decays of the form $b \rightarrow s \nu \bar{\nu}$ appear in the $\Lambda_b \rightarrow \Lambda \nu \bar{nu}$ channel, that has not yet been observed, but is a promising avenue of exploration at future $e^+e^-$...
ATLAS measurement of B0s → μ+ μ- effective lifetime with 2015-2016 data is presented. This observable, along with the branching fraction of the decay, is sensitive to New physics contributions to the decay amplitude. The measurement result is consistent with the SM.
