We address the physics implications of a precision determination of the weak charge of the proton, QWP, from a parity violating elastic electron proton scattering experiment to be performed at the Jefferson Laboratory. We present the Standard Model (SM) expression for QWP including one-loop ...
Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 x 10^-27 kg, which is 1,836 times the mass of an electron. Protons, together with electrically neutral particles calle
Using semi-local density-functional theory as well as hybrid functionals and embedded correlated wavefunction methods as higher-level benchmarks, we show that the effective charge of a solvated proton in the electrochemical double layer or outer Helmholtz plane at all levels of theory is fractional,...

interactions, which appears in all equations of microscopic electrodynamics. The elementary charge is exactly equal to the electric charge of the electron, proton, and nearly all other charged elementary particles, which by virtue of this fact are the material carriers of the smallest charge in ...
Neutron, neutral subatomic particle that, in conjunction with protons, makes up the nucleus of every atom except ordinary hydrogen (whose nucleus has one proton and no neutrons). Along with protons and electrons, it is one of the three basic particles ma

IT has recently been suggested by Bondi and Ly ttleton1,2 that the magnitudes of the electric charges on the proton and electron may differ by a little more than one part in 1018, in which case electrostatic forces would cause the universe to expand. In
