In the past decade, one of the major challenges of particle physics has been to gain an in-
depth understanding of the role of quark flavor. In this time frame, measurements and the …

In view of future plans for accurate measurements of the theoretically clean branching ratios
Br (K+→ π+ ν ν¯) and Br (KL→ π 0 ν ν¯), which should occur in the next decade, the relevant …

In recent years experiments revealed intriguing hints for new physics (NP) in B decays
involving b→ c τ ν and b→ s ℓ+ ℓ-transitions at the 4 σ and 5 σ level, respectively. In addition …

A bstract The decays\({K}^{+}\to {\pi}^{+}\nu\overline {\nu}\) and\({K} _L\to\{\pi}^ 0\nu\overline
{\nu}\), being the theoretically cleanest rare decays of mesons, are very sensitive probes of …

In this article we perform a combined analysis of low energy precision constraints and LHC
searches for leptoquarks which couple to first generation fermions. Considering all ten …

The rare decay B→ K* ν bar nu 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 …

A comprehensive analysis of tree-level weak interaction processes at low energy is
presented for the Randall-Sundrum (RS) model with SU (2) L× U (1) Y bulk gauge symmetry …

We present an extensive analysis of rare K decays, in particular of the two neutrino modes
K+→ π+ ν bar nu and KL→ π 0 ν bar nu, in the Minimal Supersymmetric extension of the …

A timely and long-term programme of kaon decay measurements at a new level of precision
is presented, leveraging the capabilities of the CERN Super Proton Synchrotron (SPS). The …

The large amount of data collected so far at B factories has allowed to reach a statistical
accuracy on B decays into pairs of (pseudo) scalars at a level where electromagnetic effects …
