8) Flavor physics - CKM and beyond
The measurement of the time-dependent CP violation parameters for B-meson decays is crucial for tightening the constraints on the unitarity triangle and for the search of new physics beyond the Standard Model.
A clean environment for the study of B decay channels is provided by B-factories. With a design luminosity of 8 · 10^35 cm^−2s^−1, leading ultimately to an integrated luminosity...

LHCb continues to expand its world-leading sample of charmed hadrons collected during LHC’s Run 1 (2010-2012) and Run 2 (2015- present). This sample is yielding some of the most stringent tests of the Standard Model understanding of charm physics. This includes precise measurements of the neutral D-meson mixing parameters and some of the most sensitive searches for direct and indirect CP...

The latest results of CP violation measurements in b hadrons at LHCb are presented. This includes recent results of time-integrated and time-dependent measurements of B mesons, such as measurements of the CKM angles gamma and phi_s, as well as measurements of b baryons.

We report recent results on B decays from Belle experiment at KEKB collider. The $B \to D^{(*)} \tau \nu $ mode is sensitive to probe New Physics such as charged Higgs or leptoquark, and the current world average of the branching ratio shows discrepancy from the Standard Model.
Belle has performed a new measurement of this mode using tau decays to hadronic final states, which is essentially...

Belle II is a major upgrade of the Belle experiment, and will operate at the B-factory SuperKEKB, located at the KEK laboratory in Tsukuba, Japan. Belle II will be an ideal laboratory to study the properties of the charm quark, collecting more than 5x10^10 ccbar events with a total integrated luminosity of about 50 ab^-1 in the next decade.
We will discuss the expected sensitivity of Belle...

The Belle II experiment at the SuperKEKB collider is a major upgrade of the KEK ``B factory'' facility in Tsukuba, Japan. The machine is designed for an instantaneous luminosity of 8x10^35 cm^-2s^-1, and the experiment is expected to accumulate a data sample of about 50 ab^-1 in five years of running. With this amount of data, decays sensitive to physics beyond the Standard Model can be...

The CKM angle gamma is the least well known of the angles of the unitarity triangle and the only one that is accessible with tree-level decays in a theoretically clean way. It provides a Standard Model benchmark against which other measurements can be compared.
The key method to measure gamma is through the interference between B^+ to D^0 K^+ and B^+ to \overline{D}^0 K^+ decays which...

Charged lepton flavor violating (CLFV) process is predicted to be out of experimental
reach by the Standard Model of elementary particle physics (SM). However, many
models of the new physics beyond the SM predicts that it is just below the
current experimental limit.
COMET searches for one of the CLFV process, mu-e conversion in a nuclear field,
improving the sensitivity by a factor of...

We evaluate the Michel parameters of $\tau$ decays using the full data sample of Belle. This is important to reveal the Lorentz structure of $\tau$ leptonic decays, which includes not only the $V - A$ interaction but also contributions from scalar, tensor and others that may arise from New Physics, thus testing lepton universality as well. We use both $\tau^+ \to l^+ \nu \bar{\nu}$ and...

K->pinunu is one of the theoretically cleanest meson decay where to look for indirect effects of new physics complementary to LHC searches. The NA62 experiment at CERN SPS is designed to measure the branching ratio of the K+->pi+nunu decay with 10% precision. NA62 took data in 2015 and 2016 reaching the Standard Model sensitivity. Recent results and prospects will be presented.

BESIII Collaboration has accumulated the world's largest e+e- collision samples at Ecm = 3.773, 4.009, 4.18 GeV. From analyses of pure leptonic decay D(s)+ -> l+v (l=mu or tau), semileptonic decays of D -> K(pi)l+v (l=e or mu), D+ -> K-pi+e+v, D+ -> omega e+v, D0(+) -> f0(980)e+v, Ds+ -> eta(')e+v, and Ds+ to eta(')e+v, we report the determinations of their absolute branching fractions, CKM...

In 2014. BESIII collected a data sample of 567 pb-1 at Ecm = 4.6 GeV, which is just above the Lambda_c+ pair production threshold. By analyzing this data sample, we have measured the absolute branching fractions for many decays of Lambda+c for the first time. These decays include the semileptonic decays of Lambda e+v, Lambda mu+v, the hadronic decays of pKs, pK-pi+, pK-pi+pi0, Lambda pi+,...
