Results from the new study suggest that symmetry, once thought to be a constant, can break down under certain conditions. This finding can reshape our understanding of the strong nuclear force, a ...

The quarks that make up the nuclei of all atoms around us are known to "mix": the different types of quark occasionally change into one another. The amounts in which these processes happen are not ...

Through the weak nuclear force, one quark flavor can transmute into another. However, current data and theory indicate that the probabilities of quark flavor transmutation do not add up to 100% ...

The charm quark is one of six quarks that, along with leptons, form the basic building blocks of ordinary matter. It is hundreds of times more massive than the up and down quarks that make up protons ...
