General Properties of the Decay Amplitudes for Massless Particles [PDF]

Nuclear Physics B, 1996
We derive the kinematical constraints which characterize the decay of any massless particle in flat spacetime. We show that in perturbation theory the decay probabilities of photons and Yang-Mills bosons vanish to all orders; the decay probability of the

Ultrafast generation and decay of a surface metal [PDF]

Nature Communications, 2021
AbstractBand bending at semiconductor surfaces induced by chemical doping or electric fields can create metallic surfaces with properties not found in the bulk, such as high electron mobility, magnetism or superconductivity. Optical generation of such metallic surfaces on ultrafast timescales would be appealing for high-speed electronics.

Natural Image Decay With a Decay Effects Generator

IEEE Access, 2023
We present a novel framework for simulating time-varying decay effects for natural images. Conventional methods assume the input image includes enough decay information and uses the color or texture information of the decayed regions to transfer its effect to the non-decayed regions.

Volumization as a Natural Generalization of Weight Decay

CoRR, 2020
We propose a novel regularization method, called \textit{volumization}, for neural networks. Inspired by physics, we define a physical volume for the weight parameters in neural networks, and we show that this method is an effective way of regularizing neural networks. Intuitively, this method interpolates between an $L_2$ and $L_\infty$ regularization.

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.

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

Stabilization of a nonlinear Euler-Bernoulli viscoelastic beam subjected to a neutral delay [PDF]

Theoretical and Applied Mechanics
An approach is implemented in this article to analyze the decay rate of nonlinear beams according to the Euler–Bernoulli equation in the context of rheological viscoelastic damping deformations taking into account the neutral type delay.

Asymptotic behavior of a viscoelastic wave equation with a delay in internal fractional feedback [PDF]

Archives of Control Sciences
We consider the viscoelastic wave equation with a time delay term in internal fractional feedback. By employing the energy method along with the Faedo-Galerkin procedure, we establish the global existence of solutions, subject to certain conditions ...

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 ...
