Decay result in a problem of a nonlinearly damped wave equation with variable exponent
AIMS Mathematics, 2022 In this work we study a wave equation with a nonlinear time dependent frictional damping of variable exponent type. The existence and uniqueness results are established using Fadeo-Galerkin approximation method.

Prompt decays of general neutralino NLSPs at the Tevatron [PDF]
Journal of High Energy Physics, 2010 Recent theoretical developments have shown that gauge mediation has a much larger parameter space of possible spectra and mixings than previously considered. Motivated by this, we explore the collider phenomenology of gauge mediation models where a general neutralino is the lightest MSSM superpartner (the NLSP), focusing on the potential reach from ...

DECAYS OF FOURTH GENERATION BOUND STATES [PDF]
International Journal of Modern Physics A, 2012 We consider the decay modes of the heavy [Formula: see text] bound states originating from Higgs boson exchange between quark–antiquark pair. In case of a small coupling between the fourth and lower generation the main decay mode is [Formula: see text] annihilation.

Evolution Equations and Control Theory, 2021 In this paper, we consider a Balakrishnan-Taylor viscoelastic wave equation with nonlinear frictional damping and logarithmic source term. By assuming a more general type of relaxation functions, we establish explicit and general decay rate results ...

HADRONIC B DECAYS: A GENERAL APPROACH [PDF]
International Journal of Modern Physics A, 2007 In this paper, we propose a general approach for describing hadronic B decays. Using this method, all amplitudes for such decays can be expressed in terms of contractions, though the matrix elements are not evaluated. Many years ago, Buras and Silvestrini proposed a similar approach. However, our technique goes beyond theirs in several ways. First, we

Asymptotic stability of a viscoelastic problem with time-varying delay in boundary feedback [PDF]
Theoretical and Applied Mechanics, 2021 In this paper, we investigate a nonlinear viscoelastic equation. By assuming time-varying delay feedback acting on the boundary, under certain assumptions on the given data, the general decay estimates for the energy are established by introducing ...

Stability result for Lord Shulman swelling porous thermo-elastic soils with distributed delay term
Open Mathematics, 2023 The Lord Shulman swelling porous thermo-elastic soil system with the presence of a distributed delay term is studied in this work. We will establish the well-posedness of the system and the exponential stability of the system is derived.

General equation for Zeno-like effects in spontaneous exponential decay [PDF]
, 1999 It was shown that different mechanisms of perturbation of spontaneous decay constant: inelastic interaction of emitted particles with particle detector, decay onto an unstable level, Rabi transition from the final state of decay (electromagnetic field ...

Third generation in cascade decays
Physical Review D, 2015 In supersymmetric models with gluinos around 1000-2000 GeV, new physics searches based on cascade decay products of the gluino are viable at the next run of the LHC. We investigate a scenario where the light stop is lighter than the gluino and both are lighter than all other squarks, and show that its signal can be established using multi b-jet, multi ...
