Could large CP-violation be detected at colliders?
(Elsevier, 1993-11-11)
We argue that CP-violation effects below a few x 10-3 are probably undetectable at hadron and electron colliders. Thus only operators whose contributions interfere with tree-level Standard Model amplitudes are detectable. ...
Stacking faults in UPt3
(Elsevier, 1993-05-02)
Atomic resolution transmission electron microscopy and X-ray diffraction measurements have been combined to investigate the microstructure of superconducting UPt3. Regions of a second double hexagonal phase with a typical ...
Search for B-decay to Higgs bosons for Higgs boson masses between 50 and 210 MeV/c2
(Elsevier, 1989-10-05)
We use data from the Mark II experiment at PEP to search for the process B-->h0X for mh0 between 50 and 210 MeV/c2. No evidence for the Higgs boson is seen in this mass range. The limit obtained rules out the standard ...
Nonlinear stationary waves and solitary waves in fluid systems with long-range forces
(Elsevier, 1993-11-15)
We study a class of nonlinear model equations which represent one-dimensional fluid systems with long range forces (such as gravity). We present elementary theorems which constrain the allowed types of stationary wave and ...
Radiative corrections to vector boson masses for heavy Higgs bosons
(Elsevier, 1986-11-27)
Radiative corrections to the masses M of the vector bosons W and Z increase in perturbation theory with increasing Higgs mass m. Since these masses will be experimentally determined to an accuracy on the order of 0.1%, ...
Canonical commutator and mass renormalization
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1989-11)
The question considered is the effect on the canonical commutation rules of mass renormalization in quantum electrodynamics. This is investigated by considering the quantum Langevin equation for a charged quantum oscillator ...
New limits on D0 (1.865) production in proton-nucleus collisions at 400 GeV/c
(Elsevier, 1977-11-21)
We present final results of a sensitive search for new particles in [pi]+/-K[mnplus] effective mass spectra observed in proton-nucleus collisions at 400 GeV/c. We establish a limit for D0 (1.865) production B[pi]+[pi]- ...
Heat conduction in Ba 1−x K x BiO 3
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1995-08)
We have investigated heat conduction of single crystal Ba 1−x K x BiO 3 in the temperature range of 2–300 K and in a magnetic field of up to 6 Tesla. Temperature dependence of thermal conductivity κ(T) reveals the participation ...
Physical consequences of mass singularities
(Elsevier, 1992-03-05)
We argue that the perturbation expansion of massless field theories are uniquely and unambiguously defined for properly formed observables. In so doing, we generalize the Kinoshita-Lee-Nauenberg theorem to show that there ...
Low-temperature electronic transport and the Coulomb blockade in oxidized films of bismuth
(Elsevier, 1990-08-06)
We present low-temperature (0.2 T e2.
