Motivation for studying such a rare decay with the LHCb Experiment. LHCb detector is dedicated to flavor physics. The upgrade of the phase II will increase the performance of detection. Especially, with the luminosity increase to reach a number of 50 collisions of protons. This is why it is important to developp the ECAL in order to not be blinded.

In this thesis analysis the meson mixing observable $y_{CP}$ has been measured via ${D^0 \rightarrow K^+ K^-}$, ${D^0 \rightarrow \pi^+ \pi^-}$ and ${D^0 \rightarrow K^- \pi^+}$ decays, where the $D^0$ comes from semileptonic decays of $B$.

This work presents the optimization of the selection of the $\Lambda_b^0 \rightarrow p K^-$ and $\Lambda_b^0 \rightarrow p \pi^-$ decay modes in order to measure their $\mathcal{CP}$ asymmetries. The optimization of the selection is crucial in the study of these decays, in order to obtain the lowest possible statistical uncertainty on the measured asymmetries.

The LHCb detector has undergone major upgrades in the last LHC shutdown and therefore the performance of the new detector has to be evaluated. Strange hadrons have huge production cross-sections and can be studied with exclusively using the detector's tracking system. Therefore, they offer the optimal starting point of evaluating the detector's performance. Additionally, an enhancement of...

Nowadays new technologies are becoming more and more present in our daily life especially in vehicles. In this presentation, I will be focused on autonomous vehicles and their sensors and more precisely the lidar. I will define what it is, how it works. I will also present the fog and the autonomous car briefly. Then, a bit of theory on lidar with fog will be explained to understand the...

The top quark is one of the fundamental fermions of the Standard Model, and is observed in the highest energy collisions. Our focus is the $t \bar t$ pair, which is produced through strong interaction in two cases: from gluon fusion ($gg$) or quark-antiquark annihilation ($q \bar q$). Different production channels lead to pairs with different characteristics: one example is the $t \bar t$ spin...

The Standard Model is currently the theory that best explains the behavior of subnuclear physics, including the definition of particles and three of the four fundamental forces acting in nature; however, it turns out to be an incomplete theory on whose integrations physicists are working in different directions: one of the most promising approaches appears to be that of effective field...

Quark-gluon plasma (QGP) is a state of matter predicted by quantum chromodynamics. The ALICE experiment at LHC has among its main goals the study of strongly interacting matter and the properties of QGP through collisions of ultra-relativistic heavy ions. For a comprehensive understanding of these properties, the same measurements made on smaller colliding systems (proton-proton and proton-ion...

In the ATLAS experiment, jets have been constructed using the calorimeter information. In a new algorithm called Particle Flow (PFlow), jets are reconstructed using the information from both the tracking system and the calorimeter. For Run-2 of the LHC, PFlow has been used and results in improved energy resolution. For Run-3, PFlow is being extended to reconstruct physical objects (electrons,...

A brief presentation about my future thesis project, the topic is entropic gravity relating to the holographic principle, AdS/CFT correspondence and black hole thermodynamics as well as experimental results, such as galaxy rotation measurments, and criticisms to the theory. The actual writing has yet to start so only surface level knowledge is given.

The Zwicky Transient Facility at Mont Palomar Observatory (California, United States) has started its survey in early 2018, for six years. ZTF project consists of a new camera of about 600 million-pixels mounted on the Samuel Oschin 48-inch Schmidt telescope. ZTF is good transient detection machine, like for Supernovae type Ia. The new dataset provided by ZTF of Supernovae Ia with its large...

Neutrinos oscillations are a quantum mechanics phenomenon for which an initial state neutrino emitted with a known flavour can be subsequently detected in a different flavour state violating the conservation of the lepton number.

Neutrino experiment results suggest that flavor can be violated for neutral leptons through neutrino oscillation, but no flavor violation has been measured for charged leptons yet. The COMET experiment at J-Parc searches for coherent neutrinoless conversion of a muon to an electron in muonic atoms ( μ- + N(A,Z) → e- + N(A,Z) ). The goal for COMET Phase-I is to reach an experimental sensitivity...

In a model with additional U(1) gauge symmetry, free of anomalies, the mass of the active neutrinos are generated by type I see saw mechanism by introducing two right handed neutrinos. The muon and tau get mass at the tree level and the masses of the electron is generated by effective operators of dimension 7 by introducing a Lambda scale. Using a Monte Carlo, the model parameters are adjusted...
