Standard Model and Fundamental Symmetries
Invited
In the talk, I will review briefly theoretical models and concepts associated with the potential violation of fundamental (space-time) symmetries, either discrete, such as T and CPT, or continuous, such as Lorentz Invariance, which may be encountered in quantum gravity. I will give an overview of how to test such symmetries, with particular emphasis on using low-energy antiprotons and cold...

Standard Model and Fundamental Symmetries
Invited
The availability of antiprotons has enabled novel experiments to
test fundamental symmetries and to determine several fundamental constants which are otherwise unaccessible. Such experiments which are primarily concerned with the simplest and lightest possible antiprotonic atom such as antiprotonic hydrogen or antiprotonic helium which are used to investigate the basic interations and...

Standard Model and Fundamental Symmetries
Contributed
The CPT invariance of all relativistic quantum field theories involved in the Standard Model defines that particles and their corresponding antiparticles have the same fundamental properties. Masses and lifetimes are identical, as well as charges and magnetic moments, the latter two with opposite sign.
BASE is testing the CPT invariance by a high-precision comparison of the proton and...

Standard Model and Fundamental Symmetries
Contributed
The CPT symmetry is a fundamental cornerstone of the Standard Model. It predicts the exact equality between the properties of particles and their antimatter counterparts. Thus, precise experimental comparisons of matter/antimatter properties provide stringent tests of the CPT symmetry. The goal of our experiment is a precise CPT test with baryons. We aim at a direct measurement of the magnetic...

Gravity and Antimatter
Contributed
The GBAR experiment (Gravitational Behaviour of Antihydrogen at Rest) [1,2] was recently accepted at CERN at its Antiproton Decelerator facility. The aim of the experiment is to perform the free fall of antihydrogen atoms (Hbar) to test the weak equivalence principle for antimatter. In order to reduce the uncertainty on the initial Hbar velocity, ultra-cold antihydrogen atoms of a few neV are...

Gravity and Antimatter
Contributed
The GBAR experiment, recently approved at the CERN AD facility, is designed to perform a direct test of the weak equivalence principle on antimatter by measuring the acceleration of anti-hydrogen atoms in the gravitational field of the Earth. GBAR will complement other experiments with antimatter by synthesizing Hbar+, to facilitate its manipulation.
Hbar+ will be obtained by two...
