New strategies for new physics search in B → K*νν̄, B → Kνν̄ and B → Xsνν̄ decays
The rare decay B → K*ν is regarded as one of the important channels in B physics as it allows a transparent study of Z penguin and other electroweak penguin effects in New Physics (NP) scenarios in
Measurement of the very rare K + → π + ν ¯ ν decay
The NA62 experiment reports the branching ratio measurement BR(K+ → π+νν̄) = (10.6+4.0 −3.4|stat ± 0.9syst)× 10−11 at 68% CL, based on the observation of 20 signal candidates with an expected
Flavor Non-universal Vector Leptoquark Imprints in $K\to \pi \nu\bar \nu$ and $\Delta F = 2$ Transitions
We analyze K → πν ¯ ν rates in a model with a TeV-scale leptoquark addressing B -meson anomalies, based on the flavor non-universal 4321 gauge group featuring third-generation quark-lepton unification.
Anomalous tqZ coupling effects in rare B- and K-meson decays
A bstractAs a top-factory, the LHC is performing a direct study of top-quark anomalous FCNC couplings, which are, however, correlated closely with the rare B- and K-meson decays. In this paper, we


Waiting for the top quark mass, K+--> pi + nu nu -bar, Bs0-B-bars0 mixing, and CP asymmetries in B decays.
In the course of the investigations, the analysis of the unitarity triangle is extended beyond the leading order in \lambda and several useful analytic formulae for quantities of interest are derived.
Weak decays beyond leading logarithms
We review the present status of QCD corrections to weak decays beyond the leading logarithmic approximation including particle-antiparti cle mixing and rare and CP violating decays. After presenting
Evidence for the Decay K+ --> pi+ nu anti-nu
An event consistent with the signature expected for the rare kaon decay K+ --> pi+ nu anti-nu has been observed. In the pion momentum region examined, 211 pi+ nu anti-nu, the branching ratio is (4.2
