General Decay of Solutions for a Coupled System of Kirchhoff-Carrier-Type Viscoelastic Wave Equations with Balakrishnan-Taylor Damping [PDF]

Sahand Communications in Mathematical Analysis
This paper examines a coupled system of Kirchhoff-Carrier-type viscoelastic wave equations with Balarkrishnan-Taylor damping. The local existence and uniqueness of solutions for the given problem are proved by utilizing the Faedo-Galerkin method and ...

The nonmesonic weak decay of the hypertriton [PDF]

, 1996
The nonmesonic decay of the hypertriton is calculated based on a hypertriton wavefunction and 3N scattering states, which are rigorous solutions of 3-body Faddeev equations using realistic NN and hyperon-nucleon interactions.

Automatic Decay-Rate Meter [PDF]

The Journal of the Acoustical Society of America, 1966
An automatic meter for measuring the decay rate in a room is described. The meter is based on a proposal by M. R. Schroeder [J. Acoust. Soc. Am. 37, 409–412 (1965)] utilizing the relationship between the integrated impulse response and the average noise response between two points in a reverberent enclosure.

Negative modes and the decay-rate transition [PDF]

Physical Review B, 1999
We investigate a relationship between the number of the negative modes around periodic instanton solution and the type of the decay-rate transition. It is shown that for the case of first-order decay-rate transition the lowest positive mode at low energy periodic instanton becomes additional negative mode at high energy regime, while in the second ...

Is \lq\lq Heavy Quark Damping Rate Puzzle'' in Hot QCD Really the Puzzle? [PDF]

, 1994
Within the framework of perturbative resummation scheme of Pisarski and Braaten, the decay- or damping-rate of a moving heavy quark (muon) to leading order in weak coupling in hot QCD (QED) is examined.

Enhancement of the Λ decay rate [PDF]

Physics Letters B, 1996
The enhancement $ ( _b)$ of the $ _b$ decay rate due to four-fermion processes of weak scattering and Pauli interference is calculated within the quark model. An estimate of the relative $bu$ wave function at zero separation, $| (0)|^2_{bu}$, is obtained in terms of the $ _b^* - _b$ hyperfine splitting, the $B^* - B$ hyperfine splitting, and ...
