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.

General decay for weak viscoelastic Kirchhoff plate equations with delay boundary conditions

Boundary Value Problems, 2017
We consider a weak viscoelastic Kirchhoff plate model with time-varying delay in the boundary. By using a suitable energy and Lyapunov function, we obtain a decay rate for the energy, which depends on the behavior of g and α.

Exponential stability of Timoshenko system in thermoelasticity of second sound with a memory and distributed delay term

Open Mathematics, 2021
This article concerns linear one-dimensional thermoelastic Timoshenko system with memory and distributed delay terms where the Cattaneo law governs the heat flux q(x,t)q\left(x,t).

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.

General decay in a Timoshenko-type system with thermoelasticity with second sound

Advances in Nonlinear Analysis, 2015
In this article, we consider a vibrating nonlinear Timoshenko system with thermoelasticity with second sound. We discuss the well-posedness and the regularity of solutions using the semi-group theory.

On a Laminated Timoshenko Beam with Nonlinear Structural Damping

Mathematical and Computational Applications, 2020
In the present work, we study a one-dimensional laminated Timoshenko beam with a single nonlinear structural damping due to interfacial slip. We use the multiplier method and some properties of convex functions to establish an explicit and general decay ...

Lorentz violation in neutron and allowed nuclear beta decay [PDF]

, 2013
We explore the possibility that the weak interaction violates Lorentz, and in particular rotational, invariance in neutron and allowed nuclear beta decay. A broad class of Lorentz-violating effects is considered, in which the standard propagator of the W-

Majorana neutrino decay in an Effective Approach [PDF]

, 2015
The search strategy or the finding of new effects for heavy neutrinos often relies on their different decay channels to detectable particles. In particular in this work we study the decay of a Majorana neutrino with interactions obtained from an ...
