El descobriment del bosó de Higgs és la culminació d’una recerca que ha durat 40 anys, i completa un marc teòric sota el qual gairebé totes del dades obtingudes de col·lisionadors de partícules poden ser explicades consistentment. Simultàniament, i paradoxalment, l’aparent con rmació d’una separacó d’escales entre l’electrofeble i la que suposadament estabilitza la masa del bosó de Higgs posa el relleu el problema de la jerarquia. En la recerca d’una descripció del món que simpli qui els patrons i simetries del Model Estàndard, l’exploració de l’escala dels TeVs i en particular l’estudi del bosó de Higgs tindran un paper central. En aquesta tesi presentem les possibilitats que el LHC i futurs col·lisionadors proveiran, amb énfasi en la determinació de l’auto-acoblament del bosó de Higgs. També considerarem l’estudi de la producció de bosons electrofebles com a eina per entendre les interaccions dels bosons de Golstone que formen part del doblet de Higgs, mostrant la seva rellevància al combinar-ho amb les dades del pol de la Z i altres cerques al LHC. Finalment, ens centrem en com el moment dipolar elèctric de l’electró posa fortes restriccions en models on el bosó de Higgs és descrit com un estat compost.<br>The discovery of the Higgs boson culminates a 40-year long hunt and completes a theoretical framework under which almost all collider data can be consistently explained. At the same time, paradoxically, the con rmation of an apparent mass gap above the electroweak scale exacerbates the problem of the electroweak hierarchy. In the search of a description of the world that simpli es the patterns and symmetries of the Standard Model, the exploration of the TeV scale and in particular the study of the Higgs boson will play a central role. In this thesis we explore the possibilities that the LHC and future colliders will bring, with particular emphasis on the determination of the Higgs self-coupling. We also consider the pair production of electroweak bosons as a probe of the Goldstone interactions in the Higgs doublet, and show its relevance as a way to improve the Z pole measurements and its interplay with other LHC searches. Finally, we focus on how the electron’s electric dipole moment can set strong constraints on models where the Higgs arises as a composite state.

@Aborde trois problématiques dans le contexte de la base de données temporelles. Ils sont le problème de regroupement, la similarité et l'extraction des stratégies. Il reste encore des problèmes pour les travaux futurs. Par exemple, comment réaliser le regroupement graduel pour d'autres algorithmes. Il sera intéressant de grouper des séquences en se basant sur notre nouveau modèle. Mais les questions posées sont le choix d'un algorithme, ou il faut un nouvel algorithme carrément ? Pour construire une stratégie, ce sera aussi possible de pré-définir nos actions. Puis trouver les relations entre les actions et les indicateurs correspondants afin de générer des stratégies. . .

Exploration has been a common literary topic throughout the history of humans. However, much of this historical tradition bas possessed a fairly narrow Ill focus, emphasizing the drama and heroics of an individual explorer or concentrating on a description of a particular exploration. There has been little attempt at understanding the process of exploration and placing this important process in context with the historic and geographic phenomena that both affect and are affected by it. In this thesis, the author has broken the process of exploration down into a theoretical structure that is presented in a holistic model. This model has then been applied to the history of 15th century Portuguese exploration to test its applicability and usefulness.

An agent is placed in an unknown environment and charged with the task of locating a lost object. What can the agent use as an efficient technique to find the object?<br>We propose a new algorithm for planar search. The algorithm stems from theoretical work on search games, in particular provably optimal search techniques on restricted domains. This thesis addresses the problem of efficiency in robotic search: having a mobile robot find a target object in an unknown environment with obstacles in an efficient manner. As a side-effect, the robot explores the environment.<br>Based on previous results, a formal description of the problem is presented along with an algorithm to solve it. This algorithm has good worst-case performance, in terms of its competitive ratio. We show experimental data validating the feasibility of our approach and typical results. Quantitative results are demonstrated showing the advantage of modified spiral search versus traditional approaches.
