We present recent results on hadronic transitions between

bottomonium states obtained by the Belle Collaboration.
They include decays of the Upsilon(4S) into lower bottomonia
with pi+pi-, eta and eta' transitions. Also discussed is the
first observation of the Upsilon(10753) state using a large
data sample collected near the Upsilon(10860) resonance.
We also briefly describe plans of... -

Decays that are very rare in the Standard Model are excellent probes for New Physics contributions,

as the Standard Model background is low and contributions from New Physics can be sizeable.
Recent measurements of decays with $b\to sll$ transitions show a pattern of anomalies, including some that hint at lepton flavour non-universal couplings.
This talk focuses on measurements that are... -

Ratios of isospin amplitudes in hadron decays are a useful probe of the interplay between weak and strong interactions, and allow searches for physics beyond the Standard Model. We present the first results on isospin amplitudes in b-baryon decays, using data corresponding to an integrated luminosity of 8.5 fb^−1, collected with the LHCb detector in pp collisions at center of mass energies of...

The ATLAS experiment has a rich $B$ physics program including measurements of CP violation in $B$ meson decays and studies of rare FCNC decays of $B$ mesons as sensitive probes of physics beyond the SM.

In this talk, recent studies of the CP violating phase $\phi_s$ in $B^0_s \to J/\Psi \phi$ and of the rare decay of $B^0$ and $B^0_s$ to muon pairs are highlighted. -

The decay $K^+ \rightarrow \pi^+ \nu \bar{\nu}$, with a very precisely predicted branching ratio of less than $10^{-10}$,is one of the best candidates to reveal indirect effects of new physics at the highest mass scales.The NA62 experiment at the CERN SPS is designed to measure the branching ratio of the $K^+ \rightarrow \pi^+ \nu \bar{\nu}$ with a decay-in-flight technique. NA62 took data so...

The NA62 experiment at the CERN SPS is designed to measure the branching ratio of the K+→π+vv ̅decay, one of the best candidates to reveal indirect effects of new physics at the highest mass scales. NA62 took data in 2016-2018. High-intensity setup and detector performance make NA62 particularly suited for searching new-physics effects from different scenarios involving feebly interacting...

The NA62 experiment at CERN collected a large sample of charged kaon decays into final states with multiple charged particles in 2016-2018. The sensitivity to a range of lepton flavour and lepton number violating kaon decays provided by this data set improves over the previously reported measurements. Results from the searches for these processes with a partial NA62 data sample are presented.

Kaons have had a great history. Many fundamental discoveries. We add to this classic list. This took ~37 + years and overcoming numerous obstacles… May be a dozen PhD’s. These new ones will deeply further our understanding of the SM and our concept of naturalness. It will provide powerful constraints on BSMs
