Parity violations in hydrogen and the fundamental structure of the weak current
(Elsevier, 1977-11-21)
Experiments in progress with hydrogen and deuterium may in practice determine the fundamental parameters and constituents of the weak interaction within the framework of unified gauge theories. In particular, for SU (2) ...
Strained layer epitaxy of InGaAs by MBE and migration enhanced epitaxy -- comparison of growth modes and surface quality
(Elsevier, 1991-05-02)
Our measurements on a series of pseudomorphic n-type modulation doped field effect transistors have shown that the mobility of the two-dimensional carriers appears to suffer from increased interface roughness as the strain ...
The quark mixing matrix in a composite model
(Elsevier, 1983-09)
The generalized mixing matrix of quarks is computed based on a composite model of quarks and leptons. Among potentials between constituent particles examined V(r) = Ars (As > 0) and A ln r (A > 0), it is shown that ...
Critical order-parameter relaxation and hypersonic attenuation in helium
(Elsevier, 1969-06-30)
The asymmetry of the temperature dependence, the broad symmetric maximum, and the frequency dependence of hypersonic attenuation in helium near the [lambda]-point can be understood qualitatively in terms of the critical ...
Validity of standard model at 90 GeV
(Elsevier, 1984-05-17)
The interpretation of the recently observed "Z"-->e+e-[gamma] events has posed a challenge to the standard model. We propose a simple test which might shed light on the underlying dynamics.
A phase cell cluster expansion for a hierarchical Ø 3 4 model
(Springer-Verlag, 1983-06)
The formalism developed in a previous paper is applied to yield a phase cell cluster expansion for a hierarchical ø 3 4 model. The field is expanded into modes with specific renormalization group scaling properties. The ...
Anomalous resistivity resulting from electrostatic ion cyclotron turbulence
(Elsevier, 1976-08-09)
An expression is found for the collisionless electrical resistivity resulting from a current driven electrostatic ion cyclotron instability.
Symmetry and symmetry breaking in generalized parastatistics
(Elsevier, 1983-09)
An analysis is made of the characteristics of internal symmetry and symmetry breaking in a quantum field theory with generalized parastatistics, defined by either double commutation relations or single commutation relations. ...
Quark mass effects and anomalies
(Elsevier, 1988-08-25)
When one takes into account that different quarks have unequal masses, five-point functions associated with pentagon graphs with two external gluons (2g) are modified by terms involving quark mass ratios. In this context ...
Regularity of critical invariant circles of the standard nontwist map
(IOP Publishing Ltd, 2005-05-01)
We study critical invariant circles of several noble rotation numbers at the edge of break-up for an area-preserving map of the cylinder, which violates the twist condition.These circles admit essentially unique parametrizations ...
