The AEgIS experiment at CERN aims to perform the first direct measurement of gravitational interaction between matter and antimatter by measuring the deviation of a cold antihydrogen beam in the Earth gravitational field. The design of the experiment has been recently updated to include emulsion films as position sensitive detector. The submicrometric position accuracy of emulsions leads...

Theory, using Low Energy QCD, calculated with high precision the $\pi\pi$ and $\pi K$ scattering length. Because these calculations are
using the chiral symmetry that describe quarks, gluons, and the QCD
vacuum property, the experimental check of these predictions is important. To check the theoretical calculations for the process
including also $s$ quarks we must measure the $\pi K$ atom...

In strange nuclear physics and hadron physics, kaonic nuclei (nuclear system with anti-kaons (Kbar)) have been a hot topic since the formation of dense state are expected due to the strong KbarN attraction. To reveal the nature of kaonic nuclei, lots of efforts have been devoted to the study of a prototype system of kaonic nuclei, "K-pp". Especially, now is the very exciting time because new...

We report on the recent advances in the project to measure the hyperfine splitting in the ground state of the muonic hydrogen atom and determine the proton Zemach radius with improved accuracy – a project that is believed to face the proton size puzzle from an alternative point of view.
Progress has been made in each of the fields that were initially considered as stumbling blocks. The...

An unusual test of CPT and quantum anomaly cancellation has been performed [1] by the ALPHA Collaboration. A bound on the charge neutrality of antihydrogen has been determined [1] through a retrospective analysis of the dynamics of antihydrogen atoms as they are released from the ALPHA trap. The analysis studies the influence of electric fields on antihydrogen dynamics under different...

Muonic atoms have an increased sensitivity on finite size effects of the
nucleus due to the ~200-fold mass of the muon compared to the electron.
The Lamb shift experiment of the CREMA collaboration in muonic hydrogen
[1] and deuterium allowed to determine the proton radius and
other nuclear properties with an order of magnitude higher precision,
compared to spectroscopic measurements of...
