Exotic atoms in which electrons are replaced by other subatomic particles of the same charge allow deep insights into the quantum world. After eight years of ongoing research, a group led by Masaki ...

For eight years, the group worked on this challenging pioneering experiment that has the potential to establish a new field of research. It was a scientific marathon, made possible by an international ...

Pionic helium In this experiment, a pion – shown here with one orange and one blue particle representing its quark and anti-quark – replaces one of the two electrons in the helium atom. This new ...

Tucson restaurateur Grant Bennett knows how to throw a restaurant grand opening. From 11 a.m. to 9 p.m. today, he’s giving away free pizzas, pastas and salads to herald the arrival of his Pionic Pizza ...

The QCD vacuum (i.e., the ground state of vacuum in the quantum chromodynamics regime) is theoretically characterized by the presence of non-zero expectation values of condensates, such as gluons and ...

The interest in exotic atoms arises from the fact that they often facilitate the most basic experimental strategy used in physics: changing a single parameter or component in an otherwise complex ...
