73. A Snowball's Chance in Hell: The Hierarchy Problem in Particle Physics

M. Andrei Angelescu (CNRS / Univ. Paris-Sud)

Particle Physics

Oral Presentation

The so-called "Hierarchy Problem" is one of the main driving forces behind the nowadays exploration of physics beyond the Standard Model (BSM). In its simplest form, the Hierarchy Problem asks why the weak interaction is $\sim {10}^{30}$ times stronger than gravity. The goal of this presentation is to state the body of the problem in a precise yet accessible manner, with a particular...

59. Looking for the neutrinoless double beta decay with the SuperNEMO detector

Particle Physics

The SuperNEMO experiment is looking for the neutrinoless double beta decay which, if observed, would prove the Majorana nature of the neutrino. Under the assumption neutrinos are indeed identical to their antiparticles, the detector could not only constrain the effective neutrino mass but also identify precisely the mechanism responsible for the neutrinoless double beta decay among the...

94. Measurement of charge exchange cross sections between positronium, proton and hydrogen

Particle Physics

Oral Presentation

The GBAR experiment will measure the free fall of antihydrogen to test the weak equivalence principle with antimatter. In order to produce this atom with a velocity of the order of 1 m/s, we will use an intermediate state, the H${}^{+}$ ion, composed of an antiproton and two positrons. This ion can be slowed to such velocities and then neutralized by photo-detachment of the excess positron. Its...

103. Research of supersymmetry with the ATLAS detector

M. Baptiste Abeloos (LAL)

Particle Physics

Oral Presentation

The supersymmetry is one of the most studied theory beyond the standard model. During the presentation, I will describe the research of supersymmetry (squarks and gluinos) with the ATLAS detector in the 0 lepton channel.
