The rare decays K+ ->pi+ nu nu are excellent processes to make tests of new physics at the highest scale complementary to LHC thanks to their theoretically cleaness.
The NA62 experiment at CERN SPS aims to collect of the order of 100 events in two years of data taking, keeping the background at the level of 10%.
Part of the experimental apparatus has been commissioned during a technical run...

New final results from an analysis of about 400 K+- --> pi+- gamma gamma rare decay candidates collected by the NA48/2 and NA62 experiments at CERN during low intensity runs with minimum bias trigger configurations are presented. The results include a model-independent decay rate measurement and fits to Chiral Perturbation Theory (ChPT) description. The data support the ChPT prediction for a...

The NA48/2 Collaboration at CERN has accumulated unprecedented statistics of rare kaon decays in the Ke4 modes Ke4(+-) to pi+ pi- e nu and Ke4(00) to pi0 pi0 e nu with ~one percent background contamination. The detailed study of form factors is sensitive to small isospin symmetry breaking effects. This brings new inputs to low energy QCD description
and crucial tests of predictions from...

The anomalous magnetic dipole moment of the muon can be both measured and computed to very high precision, making it a powerful probe to test the standard model and search for new physics such as SUSY. The previous measurement by the Brookhaven E821 experiment found a 3.6 standard deviation discrepancy from the predicted value. The new g-2 experiment at Fermilab will improve the precision by a...

CP violation and mixing in the charm meson system are expected to be very small in the standard model (SM), hence it can be a good probe to
search for new physics beyond the SM. With large relative cross-section for charmed hadron production and clean event environment combined
with high luminosity, the Belle experiment, with high statistics $e^+ e^-$ collision data taken at the KEKB...

LHCb has collected the world's largest sample of charmed hadrons. This sample is used to search for direct and indirect CP violation in charm, and to measure D0 mixing parameters. New updated measurements from several decay modes are presented, with complementary time-dependent and time-integrated analyses.

Mass and lifetime predictions of b-flavoured hadrons are an impmortant probe of QCD models. We report the world's best measurements of lifetimes of many b-flavoured mesons and baryons. We also report on observations of excited states of the B, Bs and Λb hadrons and measurements of their masses and decay widths.

The LHCb experiment has a great potential for precise measurements of the CP violating phase in the standard model, and for searches of new phases. We report on recent measurements of the CP violating angle angle γ which is the least constrained parameter in the CKM unitarity triangle, the phase in B mixing, and direct CP violation in B decays.

B meson decays provide various tests in the quark flavor structure of the standard model (SM) of particle physics, e.g. in the CP violation
and the CKM quark-mixing structure. With high statistics $B\bar{B}$ event sample collected at the KEKB $e^+ e^-$ energy-asymmetic collider
using the Belle detector, Belle has obtained numerous results in the B meson system. In this presentation, we...

Thanks to the excellent tracking and muon identification performance, combined with a flexible trigger system, the CMS experiment at the Large Hadron Collider is conducting a rich and competitive program of measurements in the field of heavy flavor physics. In this talk we review our most recent results on heavy flavour physics, based on a data sample collected by the CMS detector.

Electroweak penguin b-hadron and c-hadron decays are very sensitive to physics beyond the Standard Model. Recent LHCb measurements have shown indications of large unexpected asymmetries in B→K*μμ, hints of lepton universality violation, and the first observation of the photon polarisation in b→sγ decays. We report the most recent LHCb results in this sector.

We study the X(3872) to D bar{D} pi^0 decay within a molecular D bar{D}^* picture for the X(3872) state. This mode is more sensitive to the long-distance structure of the X(3872) resonance than its J/\psi\pi\pi and J/\psi 3pi$ decays, which are mainly controlled by the details of the X(3872) wave function at short distances. We show that the D bar{D} final state interaction can be...

One of the most intriguing puzzles in hadron spectroscopy are the
numerous charmonium-like states observed in the last decade, including charged states that are
manifestly exotic.
Over the years BaBar has extensively studied these states in B meson decays,
initial state radiation processes and two photon reactions. We report new and additional
studies on some of these states performed...

Decays of b-hadrons to light quarks allow spectroscopy measurements with a well defined initial state. The decay B(s)→J/ψππ gives insight on the quark content of the f0(500) and f0(980) mesons, while the decays B→pph and Λb→J/ψph allow for baryon spectroscopy. This talk also includes results on exotic charmonium resonances.
