The studies presented in this thesis led to the following publication:• Measurement of Inclusive Jet Cross Sections in Z/γ * (→ e + e − ) + jets Production in pp Collisions at √ s = 1.96 TeV, Phys. Rev. Lett. 100, 102001 (2008). AcknowledgmentsThe work reported in this Ph.D. thesis involved 3 years of my life, 2 continents, 3 notebooks, several terabytes of disk space, and interacting with many people.Undoubtedly, the person that most influenced this thesis is my supervisor Mario Martínez. His broad knowledge of physics and QCD in particular brought endless inputs to this thesis, and his commitment to the well-done work was a constant guidance in the processes of the analysis. Monica is the person who day by day helped me in every step of the analysis. I would like to thank her for creating such a great and friendly working environment. Alon has also helped me in the final stages of this work providing useful ideas and cross checks. Thanks also to Regis for asking and answering so many questions, his aim for perfection surely had an impact in my work.All this was possible thanks to Enrique Fernández who gave me the opportunity to work at IFAE. Special thanks go to Matteo Cavalli-Sforza who warmly welcomed me at IFAE, for sharing his neverending desire for learning and passion for physics. I would also like to express my gratitude to Ilya Korolkov, my Master Thesis supervisor, who had to deal with my learning curve in the research world and always supported and encouraged me.I would like to thank all the CDF collaborators, specially the spokespeople and the QCD conveners, for their help and inputs to the analysis, and for the success of the CDF experiment.Tota aquesta feina no hagués estat possible sense els companys i amics de l'IFAE. Primer de tot al Xavi i l'Olga, perésser els meus amfitrions a l'IFAE, que amb el temps han esdevingut més que amics. Ells em van ensenyar tot el que calia saber per sobreviure fora de la nostra estimda terra, primer al CERN, i després als Estat Units. La seva facilitat per conèixer nova gent i fer amics allí on van han fet que sempre em sentís acompanyat. I també a la Carolina, amb qui després de conèixer-nos durant la carrera vam tornar a trobar-nos a l'IFAE, el seu esperit sempre alegre i la seva rialla encomanadissa han ajudat a passar el moments més durs. We had a lot of physics and non-physics discussions with Gianluca, we shared problems and solutions, and he has been a really good friend and office-mate. I overlapped some months with Stefano in Barcelona. We did not have much time to know each other but I wish him good luck with his thesis.The friends that I met at Fermilab: Ernest,Óscar, Jónatan, Cristóbal, Kike, Miguel, Bárbara, Bruno, Arán, Ignacio, Roberto y alguno más que seguro que me olvido. Gracias a todos por crear un ambiente tan familiar y acogedor que me ha hecho sentir como en casa. Gracias sobretodo por los buenos momentos pasados fuera del trabajo, por las partidas de Go, las maratones cinematográficas, el volei, la piscina y un sinfín de cosas que nos permit...

“…The CHA [43] has the same segmentation of the CEM and every CHA tower matches a CEM tower. It uses steel as absorber material and has a depth of 4.7 interaction lengths (λ I ) (13) . To extend the coverage of the CHA, the Endwall Hadronic calorimeter (WHA) is located behind the CEM in the region 0.9 < |η| < 1.3.…”

This thesis describes the measurement of the inclusive three-jet cross section in proton-antiproton collisions at √ s = 1.96 TeV measured at the DØ experiment at the Fermilab Tevatron Collider in the Fermi National Accelerator Laboratory, Batavia, Illinois, USA. The cross section as a function of threejet invariant mass is provided in three regions of the third jet transverse momentum and three regions of jet rapidities. It utilizes a data sample collected in the so called Run IIa data taking period (2002)(2003)(2004)(2005)(2006) corresponding to the integrated luminosity of about 0.7 fb −1 . The results are used to test the next-to-leading order predictions of Quantum chromodynamics computed using the latest parton distribution functions.

“…However, direct measurement of a particle's charge under quantum chromodynamics (QCD) or color is subtle, as all of the particles that are actually detected by experiment are color-neutral. A particle's color, or at least if it has non-zero color, is inferred from jet production and quantities measured on jets [3][4][5][6][7].…”

Calculating pull for non-singlet jets

The pull vector is a jet observable sensitive to the distribution of soft radiation controlled by the color flow in a collider event. We present calculations to leading order in the soft and collinear limits for the pull vector measured between pairs of jets that do not form a color-singlet dipole. Our calculations are presented within the context of e + e − → three jets events, on which pull is measured between the two subleading jets. A subset of these calculations can be re-interpreted as a bottom-anti-bottom quark jet pair in a color octet configuration, which can be a background to Higgs production at large boost. We also present a universal expression for the pull distribution in the high-boost and small jet radius limit. This distribution is controlled by color SU(3) quadratic Casimirs that arise from product representations of pairs of QCD jets.
