Texte intégral

Résumé :

In this dissertation we study supersymmetric particles in four spacetime dimensions and their relations to other physical observables. For a large class of four-dimensional N=2 systems, the supersymmetric particles are described by the ground states of certain quiver quantum mechanics in the low energy limit. We derive a localization formula for the index of quiver quantum mechanics with four supercharges. Our answer takes the form of a residue integral on the complexified Cartan subalgebra of the gauge group. The wall-crossing phenomenon appears as discontinuities in the value of the re

Résumé :

<p> Experimental high energy physics (HEP) techniques are applied to accurate simulated collider data in search for existence or exclusion of supersymmetric (SUSY) particles. Supersymmetry is a leading candidate to resolve the hierarchy problem in particle physics as well as offer a stable dark matter candidate. Techniques and practices are explored and applied to the leptonic decay process production followed by and where is the proton, is the chargino, , are neutralinos and , are the standard model W and Higgs Bosons respectively.

Résumé :

We state and prove to all orders in perturbation theory a factorization theorem in Quantum Chromodynamics that concisely describes the separation of the physics associated with jet formation from that associated with the hard-scattering in high-energy particle collisions. We show how the factorization theorem, which provides an equality between amplitudes in gauge theories, can be readily applied to precision calculations of cross-sections. In the resulting factorized cross sections, the components relevant to jet production are universal and perturbatively calculable. Their renormalization gr

QCD higher order corrections (HOC) to three processes are considered: (i) Direct photon production in longitudinally polarized hadron-hadron collisions with numerical applications to proton-proton collisions; (ii) lepton-pair production in transversely polarized hadron-hadron collisions with numerical applications to proton-proton collisions; (iii) heavy quark pair production by polarized and unpolarized photons. The HOC to all three processes are found to be significant. Processes (i) and (ii) are shown to be sensitive probes of the proton's polarized gluon distribution and the transversity d

We discuss the experimental signatures of new particles, predicted by the Standard Model and by super symmetry, in high energy proton-antiproton and, or, electron-positron colliders. A review of the theory of the Standard Model and of Supersymmetry, and a general discussion of collider physics are included. We review various Higgs boson production mechanisms, and consider one, Higgs boson production via Bremsstrahlung from electroweak gauge bosons, in detail. We find that the clearest signature is seen in the invariant mass distribution of the electron pair in the process ρρ → X (Z → He÷e־). H

Résumé :

The interface of Cosmology and High Energy physics is a forefront area of research which is constantly undergoing development. This thesis makes various contributions to this endeavor. String-inspired cosmology is the subject of the first part of the thesis, where we propose both a new inflationary and a new alternative cosmological model. The second part of the thesis concentrates on the problems of integrating cosmology with particle physics beyond the Standard Model. Inspired by new opportunities due to stringy degrees of freedom, we propose a non-inflationary resolution of the entropy and

Résumé :

It was recently proposed that modifications to physics at trans-Planckian energies could lead to a non-adiabatic evolution of the scalar fluctuations responsible for the temperature anisotropy of the cosmological microwave background. If such a possibility was to be confirmed, it would provide us the first possibility to ever get experimental measurements of the physics near the Planck scale. This work investigates the physicality of such non-adiabatic evolutions, by avoiding the introduction of any exotic physics, by working well below the Planck scale. Simple 'hybrid-like' models of i

Résumé :

A model is presented which consists of a dynamical scheme for reproducing the mass hierarchies observed in the quark sector. This is accomplished through new physics beyond the Standard Model, and does not rely upon the Higgs mechanism. By introducing a heavy fermion which couples to the quarks via the emission and reabsorption of a new boson, initially massless quarks are given their masses in a purely radiative fashion. The differences between up and down sector masses appear naturally as a result of generating the down mass matrix from corrections to the up mass matrix: accomplished via an

One of the main concerns of the present thesis is the evaluation of symmetry-breaking effects induced by the dense matter.

A relativistic equation, known as the Kemmer-Duffin-Petiau (KDP) equation, for spin-0 particles is used to study low energy pion-nucleus scattering. This equation is linear and the optical potential is completely local in contrast to the quadratic Klein-Gordon equation which contains gradient terms in the p-wave part of the potential when applied to pion-nucleus scattering. Specifically, if we use an almost minimal coupling scheme (scalar and vector potentials), then this equation is equivalent to the Klein-Gordon equation with a Kisslinger potential and an effective Ericson-Ericson-Lorentz-Lo

Résumé :

L'étude présentée ici vise à déterminer la relation fonctionnelle existant entre la densité de grains de la trace d'une particule chargée dans l'émulsion nucléaire et le rapport p/mc de cette particule, ou p est la quantité de mouvement, m la masse et c la vitesse de la lumière. L'étude est menée a l'aide des émulsions, de type FUJI ET-7B, exposé dans le cadre de l'expérience E-531 (FNAL), ou se trouvaient réunies des émulsions nucléaires et des détecteurs électroniques, les densités de grains provenant des premières et les quantités de mouvement et les masses des seconds. La relation fonction

Résumé :

Cette these decrit le travail effectue dans l'emulsion nucleaire pour l'experience E-531 qui avait pour but de mesurer les temps de vie des particules charmees. Les plaques d'emulsion ont ete exposees au faisceau de neutrinos produit par l'interaction de protons de 400 GeV avec une cible de BeO au Fermi National Accelerator Laboratory. Les evenements neutrinos trouves ont ete analyses et les candidats charmes identifies. Un evenement en particulier a ete etudie en profondeur. Il s'agit de la desintegration par interaction faible d'une particule neutre qui n'a pu etre reconstruite en un $D\sp0$

Résumé :

We have begun development of a tool for investigating the bound state dynamics of single electron systems in intense fields. This was done by implementing the method of uniform complex scaling in a 1D test system in two different ways and have shown that the use of the "c-norm" in non-Hermitian quantum mechanics can fail for time dependent simulations. We have developed the method of complex backscaling which transforms the wavefunction from the complex scaled space back into real space and have shown that it is more robust than the "c-norm" and predicts the correct ionization when compared to
