Book Description
The associated production of a W boson and a single charm quark (W+c) is the only process in proton-proton collisions that directly probes the strange quark content of the proton. In this thesis, W+charm production is measured in proton-proton collisions at the LHC at 13 TeV, as recorded by the Compact Muon Solenoid (CMS) experiment. The analysis focuses on the identification of W bosons in their leptonic decay to a muon and a neutrino and charm quarks are tagged via the full reconstruction of D*-Mesons. The measured cross sections of W+c production are used, in combination with other relevant CMS results and the most precise HERA DIS data, in a QCD analysis to determine the strange quark content of the proton. The resulting strange quark distribution and suppression, with respect to the other light sea quarks, are in good agreement with those obtained in neutrino scattering experiments and extend their kinematic reach.

Book Description
The book provides a review of the hadronic final state measurements at HERA in deep inelastic scattering. It covers general event properties, particle spectra, heavy flavours, jets, event shape measurements, QCD instantons and small-x physics. The emphasis is on experimental results, providing quick access to the data (complete up to fall 1997) for reference. The results are discussed in the context of QCD.
Deep Inelastic Scattering: Dis 2006 - Proceedings Of The 14th International Workshop

Book Description
These proceedings present the most up-to-date status of deep inelastic scattering (DIS) physics. Topics such as structure function measurements and phenomenology, quantum chromodynamics (QCD) studies in DIS and photoproduction, spin physics and diffractive interactions are reviewed in detail, with emphasis on those studies that push the test of QCD and the Standard Model to the limits of their present range of validity, towards both the very high and the very low four-momentum transfers in lepton-proton scattering.

Book Description
'What makes this collection unusual and refreshing is that it is not the more common ‘Festschrift’ written by specialists for specialists, but a broad set of topical summaries and analyses addressed to a wide readership of particle physicists. Inevitably, some of the sections are more advanced in their treatment than others, but most of the material will be accessible and helpful to researchers at all levels, and in particular to those working on experiments at CERN, where Altarelli spent many years in the theory group. It is hard to do justice to the varied contents of this excellent collection … I can only recommend that anyone involved in particle research should turn to the web for a full description of the richness of material that is included here … There is something here for everyone, and much for most. I’m sure Altarelli would have been pleased with that! The Editors are to be complimented for their initiative in making this unique volume possible.'Contemporary PhysicsGuido Altarelli was a leading figure in 20th century particle physics. His scientific contributions and leadership played a key role in the development of the Standard Model of fundamental interactions, as well as the current search for new physics beyond it, both at and beyond CERN. This book is a collection of original contributions, at the cutting edge of scientific research, by some of the leading theoretical and experimental high-energy physicists currently in the field. These were inspired by Guido's ideas, whether directly or indirectly. This book is ideal for researchers looking to keep up with the latest developments in high-energy physics.

Book Description
Small-x Behavior of Deep Inelastic Structure Functions in QCD covers the proceedings of the DESY topical meeting entitled ""Small-x Behavior of Deep Inelastic Structure Functions in QCD"", held in DESY, Hamburg, Germany on May 14-16, 1990. The book focuses on Quantum Chromo Dynamics (QCD) structure function technology, including structure function measurements, photon structure, multi-parton interactions, and hadronic collisions. The selection first offers information on structure function measurements at Hera and pomeron and odderon in QCD and a two-dimensional conformal field theory. Topics include nucleon structure function measurements, handles on the gluon distribution, and photon structure. The book also examines Regge poles in asymptotic free theories; QCD phenomenology of parton distribution functions at small x; and possible parametrization of parton distributions. The text elaborates on low x structure function and saturation of the parton density and photon diffractive dissociation in deep inelastic scattering. The publication also considers multi-parton interactions in high energy hadronic collisions and bound-state quark and gluon contributions to structure functions in QCD. Discussions focus on bound valence-quark distributions, intrinsic gluon distribution of protons, and intrinsic charm-quark distributions. The selection is a dependable reference for readers interested in small-x behavior of deep inelastic structure functions in QCD.
