Third generation in cascade decays

open access: yesPhysical 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 ...

On the time decay for a thermoelastic laminated beam with microtemperature effects, nonlinear weight, and nonlinear time-varying delay

open access: yesAIMS Mathematics, 2023
This article examines the joint impacts of microtemperature, nonlinear structural damping, along with nonlinear time-varying delay term, and time-varying coefficient on a thermoelastic laminated beam, where, the equation representing the dynamics of slip

Long-time behavior for a nonlinear Timoshenko system: Thermal damping versus weak damping of variable-exponents type

open access: yesAIMS Mathematics, 2023
In this work, we consider a nonlinear thermoelastic Timoshenko system with a time-dependent coefficient where the heat conduction is given by Coleman-Gurtin [1]. Consequently, the Fourier and Gurtin-Pipkin laws are special cases. We prove that the system

Fractal Weyl laws and wave decay for general trapping [PDF]

open access: yes, 2017
We prove a Weyl upper bound on the number of scattering resonances in strips for manifolds with Euclidean infinite ends. In contrast with previous results, we do not make any strong structural assumptions on the geodesic flow on the trapped set (such as ...

Global existence and new decay results of a viscoelastic wave equation with variable exponent and logarithmic nonlinearities

open access: yesAIMS Mathematics, 2021
In this paper, we consider the following viscoelastic problem with variable exponent and logarithmic nonlinearities: $ u_{tt}-\Delta u+u+ \int_0^tb(t-s)\Delta u(s)ds+|u_t|^{{\gamma}(\cdot)-2}u_t = u\ln{\vert u\vert^{\alpha}}, $ where $ {\gamma}(.)

Asymptotic stability of a viscoelastic problem with time-varying delay in boundary feedback [PDF]

open access: yesTheoretical 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 ...

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

open access: yes, 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

open access: yesPhysics 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 stability for the Kirchhoff-type equation with memory boundary and acoustic boundary conditions

open access: yesBoundary Value Problems, 2017
In this paper we consider the existence and general energy decay rate of global solution to the mixed problem for the Kirchhoff-type equation with memory boundary and acoustic boundary conditions.
