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...

Measurement of the relative fraction of t$\bar{t}$ events produced via gluon fusion in p$\bar{p}$ collision at √s = 1.96 TeV at CDF

In this thesis we present a measurement of the relative fraction of tt events produced via gluon-fusion to the total number of tt events. Using the kinematics of the production and decay of the top and antitop quark pair, we trained a Neural Network to discriminate the gluon-fusion events. The Neural Network was then used as a template to fit for the gluon-fusion fraction in data. Using a total integrated luminosity of 955 pb −1 we find σ(gg→tt) σ(pp→tt) < 0.33 at 68% confidence level and σ(gg→tt) σ(pp→tt) < 0.61 at 95% confidence level.ii

“…The extent of contributions coming from the different sea quarks for the octet baryons can also be compared. To understand the relation of the Bjorken scaling variable and quark sea, it would be significant to study its implications in the region x < 0.3 which is a relatively clean region to test the quark sea structure as well as to estimate their structure functions and related quantities [20].…”

Asymmetries of quark sea in nucleon

Abstract. The effects of "quark sea" in determining the flavor structure of the octet baryons have been investigated in the chiral constituent quark model. The chiral constituent quark model is able to qualitatively generate the requisite amount of quark sea and is also known to provide a satisfactory explanation of the proton spin and related issues in the nonperturbative regime. The phenomenological implications of the quark sea asymmetries in the nucleon have been investigated to understand the importance of quark sea at lower values of the Bjorken scaling variable.After the first direct evidence for the point-like constituents in the nucleon, identified as the valence quarks with spin-1/2 in the naive constituent quark model (NQM) [1-3], a lot of experiments have been conducted to probe the structure of the proton in the deep inelastic scattering (DIS) experiments. Surprisingly, the DIS results in the early 80's [4] indicated that the valence quarks of the proton carry only about 30% of its spin and is referred to as the "proton spin crisis" in the NQM. These results provided the first evidence for the proton being composed of three valence quarks surrounded by an indistinct sea of quark-antiquark pairs (henceforth referred to as the "quark sea"). In the present day, the study of the composition of hadrons can be said to be primarily the study of the quark sea and gluons and is considered as one of the active areas in hadronic physics.The conventional expectation that the quark sea perhaps can be obtained through the perturbative production of the quark-antiquark pairs by gluons produces nearly equal numbers ofū andd. Until early 90's a symmetric sea w.r.t.ū andd was assumed, however, the famous New Muon Collaboration in 1991 [5] established the quark sea asymmetry of the unpolarized quarks in the case of nucleon by measuringd −ū giving first clear evidence for the nonperturbative origin of the quark sea. This was later confirmed by the Drell-Yan experiments [6] which measured a large quark sea asymmetry ratiō d/ū reminding us that the study of the quark sea is intrinsically a nonperturbative phenomena and it is still a big challenge to perform these calculations from the first principles of QCD.The chiral constituent quark model ( CQM) [7] can yield an adequate description of the quark sea generation through the chiral fluctuations. The basic idea is based on the possibility that chiral symmetry breaking takes place at a distance scale much smaller than the confinement scale. In this region, the effective degrees of freedom are the valence quarks and the internal Goldstone bosons (GBs) which are coupled to the valence quarks [8-10] allowing a simple and intuitive method to investigate a H.D. would like to
