The capability of LHCb to measure the $B^{+} \rightarrow K^{+} \pi^{0}$ decay mode is investigated. Analysis techniques are developed to overcome the significant challenges facing measurements of this mode and other decay channels with similar topologies. Evidence of the decay is reported for the first time at a hadron collider, and prospects for measurements made with data from Run II of the...

The difference between left- and right-handed particles is perhaps one of the most puzzling aspects of the Standard Model (SM). In left-right models (LRMs) the symmetry between left- and right-handed particles can be restored at high energy. Due to this symmetry these models are quite predictive with regards to experimental observables, making them interesting beyond the SM candidates. This...

Experiment
The differential branching fraction of the rare decay $\Lambda_{b} \rightarrow \Lambda\mu^{+}\mu^{−}$ is measured as a function of $q^2$, the square of the dimuon invariant mass. The analysis is performed using data collected by the LHCb experiment, corresponding to an integrated luminosity of 3.0 fb$^{−1}$. This includes evidence for signal at $q^2$ below the square of the $J/\psi$ mass with...

The semileptonic decay $B^+ \to \ell^+ \nu_\ell \gamma$ with $\ell^+ = e^+, \mu^+$ allows for the measurement of $\lambda_B$, which is the first moment of the $B$ meson distribution amplitude. This parameter is needed for the calculation of charmless hadronic $B$ decays in the QCD factorization scheme. The analysis is carried out with the full Belle data sample of $772\,\times 10^6 B \bar{B}$...

NA62 aims to study the rare decay $K^+ \rightarrow \pi^+ \nu \bar{\nu}$ at the CERN SPS. The status of the experiment during the 2014 commissioning run will be presented. An overview of each subdetector and a first look at the 2014 data illustrate the general progress obtained in this run.
