Hunting for new physics signals in the LHC era
2021
Actualment, el ME de física de partícules és capaç d’explicar satisfactòriament tres de les quatre interaccions fonamentals de la matèria: fortes, febles i electromagnètiques. Tot i això, hi han molts aspectes que aquesta fantàstica teoria no és capaç d’explicar i, sens dubte, ha d’haver alguna cosa més enllà d’aquesta teoria. En aquesta tesi es pretén descobrir si hi ha algun indici a les dades actuals dels acceleradors que suggerisca l’existència de nova física (NF). Pretenem, per tant, determinar fins a quin punt alguns dels models de NF que han sigut proposats a la literatura poden ser plausibles tenint en compte les dades actuals. D’aquesta forma, serem capaços de trobar restriccions s…
Complete One-Loop Renormalization of the Higgs-Electroweak Chiral Lagrangian
2018
The electroweak sector of the Standard Model can be formulated in a way similar to Chiral Perturbation Theory (ChPT), but extended by a singlet scalar. The resulting effective field theory (EFT) is called Higgs-Electroweak Chiral Lagrangian (EWCh$\mathcal{L}$) and is the most general approach to new physics in the Higgs sector. It solely assumes the pattern of symmetry breaking leading to the three electroweak Goldstone bosons (i.e. massive $W$ and $Z$) and the existence of a Higgs-like scalar particle. The power counting of the EWCh$\mathcal{L}$ is given by a generalization of the momentum expansion of ChPT. It is connected to a loop expansion, making the theory renormalizable order by ord…

Il difficoltoso percorso del Piano paesaggistico siciliano
2020
Nel 1999, la Sicilia, con anticipo rispetto alle regioni ritenute all’avanguardia nella gestione del proprio territorio e del proprio paesaggio, aveva individuato nello strumento del Piano Paesaggistico il mezzo attraverso cui perseguire la protezione e la salvaguardia del proprio patrimonio culturale e naturale. Alla caparbia e avveduta intuizione però sono succeduti anni di lungaggini amministrative, di numerosi silenzi e scellerati colpi di spugna. Dopo ventun anni, sono finalmente stati adottati e approvati i piani paesistici di gran parte dei 17 ambiti identificati dal documento del 1999. E qual è la reazione di quei territori che frattanto, in un ventennio, hanno subito non pochi camb…
Els verbs de percepció visual en català: classificació semàntica i distribució en gèneres escrits
2022
This work focuses on the study of the meanings conveyed by two visual perception verbs (mirar and veure) in Central Catalan within the theoretical framework of cognitive semantics. Our objective is twofold: (i) to analyze and describe them in order to establish metaphorical and metonymic semantic projections; and (ii) to determine the intralinguistic distribution of the non-prototypical meanings of these verbs. We have analyzed examples extracted from dictionaries (mostly DIEC2) and 1.750 forms picked out from the literary narrative and press texts of the Corpus textual informatitzat de la llengua catalana (CTILC). By analyzing these examples and the context in which they appear, we establi…
Search for pair production of first or second generation leptoquarks in proton-proton collisions at sqrt(s)=7 TeV using the ATLAS detector at the LHC
2011
This paper describes searches for the pair production of first or second generation scalar leptoquarks using 35 pb−1 of proton-proton collision data recorded by the ATLAS detector at √s=7 TeV. Leptoquarks are searched in events with two oppositely-charged muons or electrons and at least two jets, and in events with one muon or electron, missing transverse momentum and at least two jets. After event selection, the observed yields are consistent with the predicted backgrounds. Leptoquark production is excluded at the 95% CL for masses MLQ<376 (319) GeV and MLQ<422 (362) GeV for first and second generation scalar leptoquarks, respectively, when assuming the branching fraction of a leptoquark…
Analyse morphologique de talwegs et comportement scalant : applications des dimensions non-entières à la géographie physique
1999
Morphological talweg analysis and scaling behaviour: applying non-integer dimension to physical geography. -- The organisation of the talweg network is fundamental to the erosion system on the silty loamy plateaux of north-western France. The morphology of the Pays de Caux is a good example of successive runoff concentration caused by the nesting of small dry valleys. These are inherited from a periglacial climate and their general direction is governed by tectonics. However the detailed pattern of these forms remains complex and without obvious explanation. Non-integer dimensions may offer a ceratin logic to this relatively chaotic pattern. This paper has therefore sought to demonstrate th…
La formalisation fractale des tissus urbains
1998
The article concerns the fractal approach as it can bring new results making more understandable the morphology of agglomerate urban patterns. A new paradigm is developed, in order to improve the study of urban organizations according to optimization criteria. Specific fractal and multifractal methods are explicitated and applied to the knowledge of some big metropolitan areas and towns in Franche-Comté (France).
3D models acquisition and image processing for virtual musealization of the spezieria di Santa Maria della Scala, Rome
2022
This study was carried out within the project “Roma Hispana. Nuevas tecnologías aplicadas al estudio histórico, la musealización y la puesta en valor de Patrimonio Cultural español en Roma: la spezieria di Santa Maria della Scala” (Universitat de València Spain), which is funded by the Conselleria d’Innovació, Universitats, Ciència i Societat Digital of the Generalitat Valenciana (2020–2021) and authorized by the Sovrintendenza Speciale Archeologia Belle Arti e Paesaggio (Special Superintendence of Archeology, Fine Arts and Landscape) of Rome, Italy. The spezieria di Santa Maria della Scala was the oldest apothecary in…
Sul tempo di risposta di un versante a prevalente deflusso hortoniano
2005
La distinzione del bacino idrografico in versanti e reticolo attiene ai differenti processi che in essi specificamente hanno luogo. In particolare i versanti sono sede dei fenomeni diffusi di formazione del deflusso superficiale e di erosione idrica, mentre la rete è sede dei fenomeni concentrati di trasporto del deflusso liquido e solido sino alla sezione di chiusura del bacino. Nell’ipotesi che la formazione prevalente del deflusso superficiale avvenga secondo lo schema hortoniano, tipico dei versanti privi di vegetazione, nel presente lavoro è suggerita una metodologia, applicabile anche ad altre modalità di formazione, per la valutazione del tempo caratteristico di risposta del versante…
