The Vertex Locator (VELO) is a silicon microstrip detector that surrounds the proton-proton interaction region in LHCb experiment. performance of during first years its physics operation reviewed. system operated vacuum, uses bi-phase CO2 cooling system, and sensors are moved to 7 mm from LHC beam for data taking. stability these characteristic features described, details material budget given. calibration timing processing algorithms implemented FPGAs described. fully characterised. have...
EOS is an open-source software for a variety of computational tasks in flavor physics. Its use cases include theory predictions within and beyond the Standard Model particle physics, Bayesian inference parameters from experimental theoretical likelihoods, simulation pseudo events number signal processes. ensures high-performance computations through C++ back-end ease usability Python front-end. To achieve this flexibility, enables user to select implementations relevant decay processes...
The Dalitz plot analysis technique has become an increasingly important method in heavy flavour physics. Laura ++ fitter been developed as a flexible tool that can be used for analyses different experimental environments. Explicitly designed three-body decays of heavy-flavoured mesons to spinless final state particles, it is optimised order describe all possible resonant or nonresonant contributions, and accommodate CP violation effects.

We propose measurements of weighted differences the angular observables in rare decays $B \to K^*\ell^+\ell^-$. The proposed are very sensitive to difference between Wilson coefficients $\mathcal{C}_9^{(e)}$ and $\mathcal{C}_9^{(\mu)}$ for into electrons muons, respectively. At same time, charm-induced hadronic contributions kinematically suppressed $\lesssim 7\% (4\%)$ region $1\,$GeV$^2 \leq q^2 6\,$GeV$^2$, as long LFU breaking occurs only $\mathcal{C}^{(\ell)}_{9}$. This suppression...
This document contains a summary of the LHCb workshop on multi-body decays D and B mesons, held at CBPF, Rio de Janeiro, in July 2015. The was focused issues related to amplitude analysis three- four-body hadronic decays. In addition selected results, contributions from guest theorists are included.
We construct an expression for a general lepton flavour universality (LFU) ratio, $R_{X}$, in $b\to s l^+ l^-$ decays terms of series hadronic quantities which can be treated as nuisance parameters. This allows to include any LFU ratio global fits short-distance parameters, even the absence precise knowledge corresponding structure. The sizeable violation and approximate left-handed structure Standard Model amplitude imply that only very limited set parameters hamper sensitivity $R_X$...
Theory uncertainties on non-local hadronic effects limit the New Physics discovery potential of rare decays $B\to K^*\mu^+\mu^-$. We investigate prospects to disentangle in short-distance coefficients from these effects. Our approach makes use an event-by-event amplitude analysis, and relies state art parametrisation contributions. find that non-standard can be successfully disentangled The impact truncation contributions Wilson are for first time systematically examined its precise...
Rare semileptonic $b\ensuremath{\rightarrow}s{\ensuremath{\ell}}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}$ transitions provide some of the most promising frameworks to search for new physics effects. Recent analyses these decays have indicated an anomalous behavior in measurements angular distributions decay ${B}^{0}\ensuremath{\rightarrow}{K}^{*}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ and lepton-flavor-universality observables. Unambiguously establishing if deviations a...
Statistical modeling and fitting is a key element in most HEP analyses. This task usually performed the C++ based framework ROOT/RooFit. Recently community started shifting more to Python language, which tools above are only loose integrated into, lack of stable, native toolkits became clear. We presented zfit, project that aims at building ecosystem by providing carefully designed, stable API workflow for libraries communicate together with an implementation fully into ecosystem. It built...
The three-body charmless hadronic decay Bs0→KS0π+π− provides a number of novel possibilities to search for CP violation effects and test the Standard Model particle physics. These include fits Dalitz-plot distributions decay-time-integrated final state, decay-time-dependent (but without initial state flavour tagging) distribution, as well full tagged fits. relative sensitivities these different approaches are investigated.
Statistical modeling is a key element in many scientific fields and especially High-Energy Physics (HEP) analysis. The standard framework to perform this task HEP the C++ ROOT/RooFit toolkit; with Python bindings that are only loosely integrated into ecosystem. In paper, zfit, new alternative RooFit written pure Python, presented. Most of all, zfit provides well defined high-level API workflow for advanced model building fitting, together an implementation on top TensorFlow, allowing...
