Muons continually bombard the ground at a known rate and angular distribution. As muons lose energy when passing through matter, their flux is attenuated depending on the integrated density along ...

A recent study offers proof of feasibility for using cosmic radiation detectors to discover underground spaces. The detectors identify muons—particles created when cosmic radiation collides with Earth ...

James Dacey investigates a plan to use muons to peer inside the throat of Mexico’s famous volcano, Popocatépetl, to help predict the timing and extent of its fiery outbursts Fiery mountain ...

Once a surprise to physicists, these particles are useful tools inside and outside the realm of particle physics. Every minute, countless muons rain down from space, passing through ...
