The Mu2e Experiment at Fermilab will search for coherent, neutrino-less
conversion of muons into electrons in the field of a nucleus with a
sensitivity improvement of a factor of 10,000 over existing limits. Such a
lepton flavor-violating reaction probes new physics at a scale
inaccessible with direct searches at either present or planned high energy
colliders. The experiment both...

Study of rare decays is an important approach to search for new physics beyond the Standard Model. The branching ratio of charged pion decays, `$R={\Gamma}({\pi}^+{\rightarrow}e^{+}{\nu}_{e}({\gamma}))$/${\Gamma}({\pi}^+{\rightarrow}{\mu}^+{\nu}_{\mu}({\gamma}))$` is one of the most precisely calculated processes involving quarks with `$R_{SM}=(1.2352{\pm}0.0001)$` `${\times}10^{-4}$`. Precise...

We present a selection of recent results obtained by using the data collected with the BaBar detector at the PEP-II e+e- B-factory, with particular emphasis on measurements probing the discrete symmetries in beauty and charm decays. These include the measurements of partial decay rates and CP asymmetries of the inclusive decays B -> Xs l+ l- and B -> Xs gamma; searches for lepton number...

We report on the latest searches for low mass states predicted in several
New Physics models performed with the data collected by the BABAR detector.
These include:
searches for the so-called dark photons in e+e- annihilations (e+e- -> gamma A’, A’ -> e+e-, mu+mu-), and for long-lived particles motivated by recent astrophysical observations;
searches for non-standard pi0-like particle...

The Belle II experiment is now being constructed
at the KEK laboratory in Japan. This project represents
a substantial upgrade to both the Belle detector and
the KEKB accelerator. The Belle II experiment will
record 50~ab$^{-1}$ of data, a factor of 50 more than
that recorded by the Belle experiment. This large data set,
combined with the low backgrounds and high trigger...

We search for the decay $B_{s}\rightarrow\gamma\gamma$ and measure the branching fraction for $B_{s}\rightarrow\phi\gamma$ using 121.4~$\textrm{fb}^{-1}$ of data collected at the $\Upsilon(\mathrm{5}S)$ resonance with the Belle detector at the KEKB asymmetric energy B-factory located at the High Energy Accelerator Research Organization (KEK), Japan. These are flavor changing neutral current...
