L'expérience HPS (Heavy Photon Search) au Jefferson Lab (USA)recherche un nouveau boson de jauge vecteur, nommé "photon lourd" ou "photon sombre", dans une fourchette de masse allant de 20 à 1000 MeV. Une telle particule couplerait avec le photon du modèle standard par effet de "kinetic mixing" et pourrait ainsi être émis par l'intermédiaire d'électrons. En utilisant un faisceau d'électron de haute intensité d’un à six GeV envoyé sur une cible de tungstène, HPS cherche à détecter une fine résonance dans le bruit de fond produit par les processus QED qui serait la signature d'un photon lourd. HPS exploitera aussi le fait qu'à très petit couplages, le photon lourd se désintègrera après une distance détectable, fournissant ainsi une seconde signature sous la forme d'un vertex éloigné de la cible. Dans cette thèse, je présente les motivations pour une telle recherche de photon lourd dans ce domaine spécifique de l'espace de phase, puis je présente le spectromètre HPS, en détaillant en particulier le calorimètre électromagnétique qui a été l'un de mes sujets d'étude. Ensuite, je présente mon travail utilisant une intégration Monte-Carlo pour calculer la section efficace des processus QED attendus dans l'expérience HPS. Finalement, je présente dans cette thèse mon analyse de donnée pour la recherche d'un pic sur le bruit de fond QED dans les données acquises au printemps 2015.

The heavy photon search (HPS) experiment in Jefferson Lab (USA) is looking for a new vector gauge boson, called "heavy photon" or "dark photon", in a mass range of 20 MeV to 1000 MeV. Such particle can couple to the standard model photon through kinetic mixing and therefore can be radiated in electron scatterings. Using a high intensity, one to six GeV electron beam sent onto a tungsten target, HPS will look for a narrow resonance above the QED background that would be a signature of a dark photon. HPS will also exploit the fact that for small couplings, this dark photon would also travel a detectable distance before decaying, providing a second signature in the form of a vertex away from the target. In this thesis, I will present the motivations to look for such a dark photon in this particular domain of phase space, then present the HPS spectrometer, with a particular focus on the electromagnetic calorimeter which was a focus of my work. Then, I will present my work using a Monte-Carlo integration to calculate the cross section of the expected background QED processes for the HPS experiment. The final part of my work presented in this thesis will be focused on my data analysis, looking for a bump on the QED background, I carried out using data taken in Spring 2015.

▼ The parity violating weak decay of hyperons offers a valuable means of measuring their polarization, providing insight into the production of strange quarks and the matter they compose. Jefferson Lab’s CLAS collaboration has utilized this property of hyperons, publishing the most precise polarization measurements for the Λ and Σ in both photoproduction and electroproduction to date. In contrast, cascades, which contain two strange quarks, can only be produced through indirect processes and as a result, exhibit low cross sections thus remaining experimentally elusive. At present, there are two aspects in cascade physics where progress has been minimal: characterizing their production mechanism, which lacks theoretical and experimental developments, and observation of the numerous excited cascade resonances that are required to exist by flavor SU(3)F symmetry. However, CLAS data were collected in 2008 with a luminosity of 68 pb−1 using a circularly polarized photon beam with energies up to 5.45 GeV, incident on a liquid hydrogen target. This dataset is, at present, the world’s largest for meson photoproduction in its energy range and provides a unique opportunity to study cascade physics with polarization measurements. The current analysis explores hyperon production through the γp → K+K+Ξ− reaction by providing the first ever determination of spin observables P, Cx and Cz for the cascade. Three of our primary goals are to test the only cascade photoproduction model in existence, examine the underlying processes that give rise to hyperon polarization, and to stimulate future theoretical developments while providing constraints for their parameters. Our research is part of a broader program to understand the production of strange quarks and hadrons with strangeness. The remainder of this document discusses the motivation behind such research, the method of data collection, details of their analysis, and the significance of our results.
