Moreover, there is no evidence for the existence of any isolated charged particle whose electric charge is not an integer multiple of the electron charge. This is referred to as charge quantization.

Furthermore, the four fold degenerate J = 3/2 hole bands further split at non-zero k. These bands with Jz = ±3/2 and Jz = ±1/2 are called the heavy ...

Ionization Dynamics of Molecules in Intense Laser Fields

In the present context an intense laser field is characterized by a field strength which is comparable to the Coulomb interaction between the electrons and the nuclei. The typical intensit ...

A previously-proposed method of constructing spatially-extended gauge-invariant three-quark operators for use in Monte Carlo lattice QCD calculations is tested, and a methodology for using these operators to extract the energies of a large number of baryon states is developed. This work is part of a ...

Muon Decay

And yet we continuously measure these particles at sea level. Something must be wrong here. Or there is something special happening. Whe ...
