The Baryon Antibaryon Symmetry Experiment (BASE) at CERN's Antimatter Factory has set new limits on the existence of axion-like particles, and how easily those in a narrow mass range around 2.97 neV could turn into photons, ...

The perfect transmission of sound through a barrier is difficult to achieve, if not impossible based on our existing knowledge. This is also true with other energy forms such as light and heat.

The positively charged protons in atomic nuclei should actually repel each other, and yet even heavy nuclei with many protons and neutrons stick together. The so-called strong interaction is responsible for this. Prof. Laura ...

In particle physics, three out of the four known fundamental forces in the universe, namely electromagnetic, weak and strong interactions, are described by a theory known as the standard model (SM). One extension of this ...
At the 40th ICHEP conference, the ATLAS and CMS experiments announced new results which show that the Higgs boson decays into two muons. The muon is a heavier copy of the electron, one of the elementary particles that constitute ...
