Can Cosmic Ray Catalysed Vacuum Decay Dominate Over Tunnelling? [PDF]

, 1997
We consider the question of whether cosmic ray catalysed false vacuum decay can be phenomenologically more important than spontaneous decay via quantum tunnelling.

Four generations and the decay

Physics Letters B, 1987
Abstract In the standard model with four generations the rate for K + → π + ν ν can be either enhanced or suspressed as compared to the three-generation case, depending on the values of quark mixing angles and masses. The upper limit for the branching ratio increases for all mt values, and is always higher than 10−9.

General decay and blow-up of solutions for a nonlinear wave equation with memory and fractional boundary damping terms [PDF]

Boundary Value Problems, 2020
The paper studies the global existence and general decay of solutions using Lyapunov functional for a nonlinear wave equation, taking into account the fractional derivative boundary condition and memory term.

New Generation of Neutron Decay Experiments [PDF]

Journal of Neutron Research, 2005
New generation of neutron decay experiments, which can be done with high accuracy at new Spallation Neutron Sources, are very important for solution of current problems of fundamental physics and for tests of the Standard Model. The open problems of theory related to these experiments and possible approaches to their solutions are discussed.

The generational decay of Euroscepticism in the UK and the EU referendum [PDF]

Journal of Elections, Public Opinion and Parties, 2017
A prominent feature of media coverage during the UK’s referendum on European Union (EU) membership was the stark difference between the pro-EU young and their Eurosceptic elders, widely assumed to reflect a generational divide. The positive relationship between age and hostility towards the EU is well established in academic research, however only Down,

Properties of hadronicZ decays and test of QCD generators [PDF]

Zeitschrift f�r Physik C Particles and Fields, 1992
Distributions are presented of event shape variables, jet roduction rates and charged particle momenta obtained from 53 000 hadronicZ decays. They are compared to the predictions of the QCD+hadronization models JETSET, ARIADNE and HERWIG, and are used to optimize several model parameters.

Magnetic Field Decay in Neutron Stars. Analysis of General Relativistic Effects [PDF]

, 2000
An analysis of the role of general relativistic effects on the decay of neutron star's magnetic field is presented. At first, a generalized induction equation on an arbitrary static background geometry has been derived and, secondly, by a combination of ...

Classical Loschmidt echo in chaotic many-body systems [PDF]

, 2005
General theoretic approach to classical Loschmidt echoes in chaotic systems with many degrees of freedom is developed. For perturbations which affect essentially all degrees of freedom we find a doubly exponential decay with the rate determined by the ...
