This book was released on 2017 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes a measurement of the differential top quark pair production cross section for top quarks with high transverse momentum (pt) in proton-proton collisions at a center-of-mass energy of 13 TeV. The measurement is performed using data collected by the CMS experiment during the 2016 data-taking period, corresponding to an integrated luminosity of 35.9 fb-1. The measurement is performed using events where one top quark decays hadronically and is reconstructed as a single large-radius t jet with pt > 400 GeV, while the other top quark decays leptonically to a b jet, an electron or a muon, and a neutrino. Jet substructure techniques are used to identify the large-radius jet as a t jet candidate. The measurement demonstrates that current simulations overpredict the rate of top quark pair production at high pt, providing valuable feedback on the accuracy of current simulation.

Available in PDF, EPUB and Kindle. Book excerpt: Measurements are presented of the t-channel single-top-quark production cross section in proton-proton collisions at √s = 8 TeV. The results are based on a data sample corresponding to an integrated luminosity of 19.7 fb−1 recorded with the CMS detector at the LHC. The cross section is measured inclusively, as well as separately for top (t) and antitop $ \left(\overline{\mathrm{t}}\right) $, in final states with a muon or an electron. The measured inclusive t-channel cross section is?t-ch. = 83.6 ± 2.3 (stat.) ± 7.4 (syst.) pb. The single t and $ \overline{\mathrm{t}} $ cross sections are measured to be?t-ch.(t) = 53.8 ± 1.5 (stat.) ± 4.4 (syst.) pb and?$_{t-ch.}$ $ \left(\overline{t}\right) $ = 27.6 ± 1.3 (stat.) ± 3.7 (syst.) pb, respectively. The measured ratio of cross sections is Rt-ch. =?t-ch.(t)/?t-ch. $ \left(\overline{\mathrm{t}}\right) $ = 1.95 ± 0.10 (stat.) ± 0.19 (syst.), in agreement with the standard model prediction. The modulus of the Cabibbo-Kobayashi-Maskawa matrix element Vtb is extracted and, in combination with a previous CMS result at √s = 7 TeV, a value.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The cross section for the production of single top quarks in the $t$ channel is measured in proton-proton collisions at 13 TeV with the CMS detector at the LHC. The analyzed data correspond to an integrated luminosity of 2.3 fb$^{-1}$. The event selection requires one muon and two jets where one of the jets is identified as originating from a bottom quark. Several kinematic variables are then combined into a multivariate discriminator to distinguish signal from background events. A fit to the distribution of the discriminating variable yields a total cross section of 232 $\pm$ 13 (stat) $\pm$ 28 (syst) pb and a ratio of top quark and top antiquark production of $R_{t\textrm{-ch.}}= $ 1.81 $\pm$ 0.18 (stat) $\pm$ 0.15 (syst). From the total cross section the absolute value of the CKM matrix element $V_{\mathrm{tb}}$ is calculated to be 1.03 $\pm$ 0.07 (exp) $\pm$ 0.02 (theo). All results are in agreement with the standard model predictions.

This book was released on 2021-07-14 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to Lev Okun, who passed away in November 2015. He was a true pioneer in probing fundamental dynamics.The book has two objectives. First is to showcase Okun's impact for decades since 1963, when he published his remarkable book Weak Interaction of Elementary Particles. Second is to present the current progress of our scientific community in the studies of our Universe. New directions and possible future developments are discussed, often using the past as a guide. The authors mostly focus on CP asymmetries in the transitions of hadrons and leptons, but they also discuss their rare decays, and talk about axions and supersymmetry, and possible connections with dark matter, extra dimensions, baryogenesis and multiverse.This book is suitable for readers who know quantum mechanics and quantum field theories in general.
Book Synopsis Measurement of the Single Top TW Associated Production Cross Section at 7 TeV with 4.9 Fb-1 of Data in the Dilepton Decay Channel at the LHC Using the CMS Detector by : William Patrick Martin
Download or read book Measurement of the Single Top TW Associated Production Cross Section at 7 TeV with 4.9 Fb-1 of Data in the Dilepton Decay Channel at the LHC Using the CMS Detector written by William Patrick Martin and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The first measurement of the production cross section for a single top quark in association with a W boson with the CMS experiment at the Large Hadron Collider is presented. The analysed data is from proton-proton collisions at a centre-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 4.9 fb-1. The analysis focuses on the leptonic final states of the process and implements a cut-based method. The final state consists of two leptons, two neutrinos and a jet from the fragmentation of a b-quark. The primary source of background events arises from tt(overbar) production, followed by Z/gamma* processes. The observed signal has a significance of 3:5sigma and corresponds to a cross section measurement of 14:9+5:0 -5:1 (stat + syst) pb, in agreement with the Standard Model expectations.
