65. Search for the SM (and BSM) production of four top quarks in the ATLAS detector at the LHC

The top quark is the heaviest elementary particle we know. Therefore, it plays a very special role in the Standard Model of particle physics (SM). Its Yukawa coupling to the Higgs boson is close to one, which makes this particle a key element of many Beyond the Standard Model (BSM) theories. The LHC, located at CERN (Geneva, Switzerland) is a proton - proton collider with a center-of-mass...

66. Phenomenological analysis of μ-e conversion in nuclei

Albert Druesnes-Saporta (Institut de Physique Nucléaire de Lyon)

01/12/2017 10:00

I will present the analysis of the μ − e conversion process in a scenario Beyond the Standard Model (BSM), using an effective field theory (EFT) approach. In a first part, I will discuss what is an effective field theory and why we need it. In a second part I will discuss how to use effective field theories to constrain BSM models like μ-e conversion.

67. Search for branons in hadronic final states in proton-proton collisions at sqrt(s) = 13 TeV at CMS

In order to solve the hierarchy problem and to answer the question “what is Dark Matter ?”, many models involving additional spatial dimensions have been proposed. Among them is the branon model, which predicts the production of branons, scalar Dark Matter candidates, along with Standard Model particles. This study proposes to search for branon production at center of mass 13 TeV in hadronic...

68. Recherche de bosons de Higgs supplémentaires dans le cadre des théories 2HDM par l'observation de désintégration H->tau tau dans l’expérience CMS du LHC

Gaël Touquet (IPNL)

Le Modèle Standard décrit les constituants élémentaires de la matière ainsi que les forces fondamentales leur permettant d'interagir : électromagnétisme, interaction nucléaire forte, et interaction nucléaire faible. Le boson de Higgs est la pierre angulaire du modèle standard pour deux raisons. D'une part, le champ de Higgs provient de la brisure spontanée de la symétrie électrofaible et il...
