The uncertainty principle of quantum mechanics states that the elementary particles which make up a neutron—an up quark and two down quarks—can spontaneously transform into much heavier particles for a brief periods of time. Those heavier particles may be either known particles from the Standard Mod ...

The corresponding production of W , eg. e− ν̄e → W − → fermions is not technically feasible since we cannot create a beam of neutrinos which is well enough ...

HIGH ENERGY PARTICLE COLLIDERS: PAST 20 YEARS, NEXT 20
... (here, all the parameters are for the opposite bunch, and rc=e2/mc2 is the classical radius of the particles) and can reach the value of ξ~0.03 in hadron colliders to ~0.13 in lepton colliders. Beyond this limit, a variety of so called “beam-beam effects” have usually led to intolerable operational ...

Vibrations and Rotations of Diatomic Molecules at Surfaces
... This thesis presents theoretical studies of the vibrational and rotational character of diatomic molecules at surfaces. Two and three-dimensional PESs have been constructed for non-dissociative adsorption of H2 and N2 on Cu(111) and for H2 on Cu(510), using density functional theory (DFT). The adsor ...

Mean Multiplicity of Quark and Gluon Jets as a Function of Opening

The jet energy is held fixed for every 5 GeV between 15–30 GeV energies and the mean multiplicity of b-quark and gluon jets are obtained as function of the angle between them. It i ...
