The production of jets in association with Z bosons, reconstructed via the mu+mu- and e+e- decay channels, is studied in pp and, for the first time, in PbPb collisions. Both data samples were collected by the CMS experiment at the LHC, at a center-of-mass energy of 5.02 TeV. The PbPb collisions were analyzed in the 0-30% centrality range. The back-to-back azimuthal alignment was studied in both pp and PbPb collisions for Z bosons with transverse momentum ptz> 60 GeV/c and a recoiling jet with ptj> 30 GeV/c. The pt imbalance, xjz= ptj/ptz, as well as the average number of jet partners per Z, rjz, were studied in intervals of ptz, in both pp and PbPb collisions. The rjz is found to be smaller in PbPb than in pp collisions, which suggests that in PbPb collisions a larger fraction of partons, associated with the Z bosons, lose energy and fall below the 30 GeV/c ptj threshold.

This volume gathers the content of the courses held at the Third IDPASC School, which took place in San Martiño Pinario, Hospederia and Seminario Maior, in the city of Santiago de Compostela, Galiza, Spain, from January 21st to February 2nd, 2013. This school is the annual joint program of the International Doctorate Network in Particle Physics, Astrophysics, and Cosmology (IDPASC). The purpose of the school series is to present doctoral students from different universities and laboratories in Europe and beyond with a broad range of the latest results and current state of the art in the fields of Particle Physics, Astrophysics, and Cosmology, and to further introduce them to both the questions now posed by the potentials of physics and to challenges connected with current and future experiments – in particular, with the newly available energy ranges. Following these guidelines, the content of this third edition of the IDPASC School was jointly planned by the Academic Council and by the network’s International Committee, whose members ensure every year its timely formulation, keeping up with the constant evolution of these fields. The program covers a balanced range of the latest developments in these fields worldwide, with courses offered by internationally acknowledged physicists on the Basic Features of Hadronic Processes, Quantum Chromodynamics, Physics and Technology of ALICE, LHCb Physics-Parity Violation, the Higgs System in and beyond the Standard Model, Higgs Searches at the LHC, Theory and Experiments with Cosmic Rays, Numerical Methods and Data Analysis in Particle Physics, Theoretical Cosmology, and AdS/CFT Correspondence. Most of these courses were complemented by practical and discussion sessions.

This book offers a deep dive into quantum teleportation and immune noise models, providing cutting-edge solutions to challenges in noisy quantum communication systems. It covers advanced theories and practical methods for building robust, high-fidelity quantum channels that ensure secure communication even in noisy environments, making it a vital resource for researchers and professionals in quantum information science. Key topics include quantum teleportation protocols, immune noise models, quantum information splitting, and multi-degree-of-freedom quantum teleportation. By developing a unified framework for high-fidelity quantum channels, the book tackles major issues like "entanglement death," decoherence, and channel capacity limitations. It offers solutions to improve quantum state fidelity, channel performance, and security, enhancing the practicality of quantum teleportation in areas like national defense, finance, and secure communication. The book targets academic researchers, engineers, and professionals in quantum information, cryptography, and secure communications, along with advanced students interested in quantum teleportation in noisy environments.

Jets have long been used as an effective probe for exploring the properties of the quark-gluon plasma (QGP) produced in high energy collisions of nuclei [1]. In heavy ion collisions some nucleons will undergo hard scattering, breaking apart and releasing their constituent high transverse momentum partons. These partons undergo hadronization due to the phenomenon of colour confinement. This is a process in which, as the constituent partons separate, the strong coupling constant increases until there is enough potential energy for it to be more energetically favourable to produce a quark-antiquark pair. This radiates more partons, predominantly collinear with their parent, forming jets of particles. As the energy of these particles decrease they will form colourless hadrons which can be detected. We set out with the aim to establish a groundwork for measuring the shape of the QGP by examining the energy loss of jets with respect to the azimuthal angle. By examining Z+jet events we aim to accurately measure the jet energy lost through jet quenching in the QGP. We expect jets which have traversed a larger distance in the QGP to lose more energy and thus an azimuthal anisotropy of jet energy loss will give us information on the shape of the produced QGP. While the latest run at the LHC did not yield many Z events from PbPb collisions [2] the next run should provide the data necessary for a complete analysis of this type. We will make use of a dijet enhanced Monte Carlo (MC) dataset in order to plan out the process and collect preliminary results.

Jet production in PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76 TeV was studied with the CMS detector at the LHC, using a data sample corresponding to an integrated luminosity of 6.7 inverse microbarns. Jets are reconstructed using the energy deposited in the CMS calorimeters and studied as a function of collision centrality. With increasing collision centrality, a striking imbalance in dijet transverse momentum is observed, consistent with jet quenching. The observed effect extends from the lower cut-off used in this study (jet transverse momentum = 120 GeV/c) up to the statistical limit of the available data sample (jet transverse momentum approximately 210 GeV/c). Correlations of charged particle tracks with jets indicate that the momentum imbalance is accompanied by a softening of the fragmentation pattern of the second most energetic, away-side jet. The dijet momentum balance is recovered when integrating low transverse momentum particles distributed over a wide angular range relative to the direction of the away-side jet.
