Q-ball Evolution, B-ball Baryogenesis and the f_{B} Problem
John McDonald
We consider some of the issues surrounding the formation and evolution of Q-balls in the MSSM and its extensions. The ratio of the baryon number packed into Q-balls to that outside…
A Comparison of the Momentum Spectra in Deep Inelastic Scattering with the Modified Leading Logarithmic Approximation
N H Brook, I O Skillicorn
The evolution of the logarithmic scaled energy spectra with energy scale, in the framework of the modified leading logarithmic approximation (MLLA), is investigated. The behaviour…
Neutrino Oscillations in Extended Anti-GUT Model
C. D. Froggatt, H. B. Nielsen, Y. Takanishi
What we call the Anti-GUT model is extended a bit to include also right-handed neutrinos and thus make use of the see-saw mechanism for neutrino masses. This model consists in assi…
Non-Thermal Dark Matter, High Energy Cosmic Rays and Late-Decaying Particles From Inflationary Quantum Fluctuations
John McDonald
It has been suggested that the origin of cosmic rays above the GZK limit might be explained by the decay of particles, X, with mass of the order of 10^{12} GeV. Generation of heavy…
Color Superconductivity in Compact Stars
Mark Alford, Jeffrey A. Bowers, Krishna Rajagopal
After a brief review of the phenomena expected in cold dense quark matter, color superconductivity and color-flavor locking, we sketch some implications of recent developments in o…
Dynamical Cosmological Constant from A Very Recent Phase Transition
John McDonald
Observation indicates that the expansion of the Universe is accelerating and favours a dynamical cosmological constant, Λ(t). We consider the possibility that this is due to a scal…
Inflaton Particles in Reheating
A. B. Henriques, R. G. Moorhouse
In many theories of reheating starting from the classical spatially homogeneous inflaton field, its accompanying inhomogeneous part (which arises from primordial quantum fluctuatio…
Lepton Number Violation in Supersymmetric Grand Unified Theories
J. L. Chkareuli, C. D. Froggatt
We argue that the nature of the global conservation laws in Supersymmetric Grand Unified Theories is determined by the basic vacuum configuration in the model rather than its Lagra…
Flat direction condensate instabilities in the MSSM
K. Enqvist, A. Jokinen, J. McDonald
Coherently oscillating scalar condensates formed along flat directions of the MSSM scalar potential are unstable with respect to spatial perturbations if the potential is flatter t…
From Prototype SU(5) to Realistic SU(7) SUSY GUT
J. L. Chkareuli, C. D. Froggatt, I. G. Gogoladze +1
We construct a realistic SU(7) model which provides answers to many questions presently facing the prototype SU(5) SUSY GUT. Among them are a solution to the doublet-triplet splitt…
The Evolution of the MLLA Parton Spectra
N. H. Brook, I. O. Skillicorn
The evolution with energy scale of the partonic logarithmic scaled energy spectra is investigated in the framework of the modified leading logarithmic approximation (MLLA). The beh…
Post-Inflationary Reheating
A. B. Henriques, R. G. Moorhouse
We study a model for reheating that has been much investigated for parametric resonance, having a quartic interaction of the scalar inflaton with another scalar field. Attention is…
Scaling of the B and D meson spectrum in lattice QCD
J. Hein, S. Collins, C. T. H. Davies +5
We give results for the and the meson spectrum using NRQCD on the lattice in the quenched approximation. The masses of radially and orbitally excited states are calculated…
Inflationary Affleck-Dine Scalar Dynamics and Isocurvature Perturbations
Kari Enqvist, John McDonald
We consider the evolution of the Affleck-Dine scalar during D-term and F-term inflation and solve the combined slow-roll equations of motion. We show that for a typical case, where…
