Quarks and hadrons

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. Consistent ...

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
... When an atom or a molecule is exposed to a intense laser field a series of nonperturbative phenomena may occur. 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 ...

The FrPNC collaboration proposes to measure both optical PNC and the nuclear anapole moment in a chain of lasercooled francium isotopes produced by spallation of a uranium carbide target with 500 MeV protons at the ISAC facility at TRIUMF. Both experiments measure the degree of PNC-induced mixing of ...

Muon Decay

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