Book Description
The authors present the first measurement of the production cross section of a W boson with a single charm quark (c) in p{bar p} collisions at √s = 1.96 TeV, using soft muon tagging of c jets. In a data sample of ≈ 1.8 fb−1, recorded with the CDF II detector at the Fermilab Tevatron, they select events with W + 1 or 2 jets. They use the charge correlation between the W and the muon from the semileptonic decay of a charm hadron to extract the We signal. They measure [sigma]{sub Wc} (p{sub Tc} > 20 GeV/c,

Book Description
Scientific knowledge experienced an age of explosion during the XX century, fruitful in discoveries that radically changed the perspective we had of Nature. Our current quest is, however, to continue questioning the fundamental aspects of everything that surrounds us, to test until the very end how far the great theories can go, and to pursue with the undeniable task of human restlessness to answer the question “and why is that?”. In the specific topic of this work, we will make use of the largest machine ever built to obtain information about some of the smallest elements of matter, measuring with the best precision up to date the cross section of a process that could shed some light on the mystery of fundamental asymmetry between matter and antimatter in the Universe. Our mind demands symmetry...

Book Description
We present the first direct measurement of the W production charge asymmetry as a function of the W boson rapidity y{sub W} in p{bar p} collisions at √s = 1.96 TeV. We use a sample of W → e[nu] events in data from 1 fb−1 of integrated luminosity collected using the CDF II detector. In the region

Book Description
Measurements are presented of the associated production of a W boson and a charm-quark jet (W + c) in pp collisions at a center-of-mass energy of 7 TeV. The analysis is conducted with a data sample corresponding to a total integrated luminosity of 5 inverse femtobarns, collected by the CMS detector at the LHC. W boson candidates are identified by their decay into a charged lepton (muon or electron) and a neutrino. The W + c measurements are performed for charm-quark jets in the kinematic region $p_T^{jet} \gt$ 25 GeV, $

Book Description
The production cross section of a W boson in association with two b jets is measured using a sample of proton-proton collisions at $ \sqrt{s} = $ 8 TeV collected by the CMS experiment at the CERN LHC. The data sample corresponds to an integrated luminosity of 19.8 fb$^{-1}$. The W bosons are reconstructed via their leptonic decays, $ \mathrm{ W }\to\ell\nu $, where $\ell=\mu$ or $\mathrm{ e }$. The fiducial region studied contains exactly one lepton with transverse momentum $ p_{\mathrm{T}}^{\ell}> $ 30 GeV and pseudorapidity $
