Are there quasistable hadrons containing superheavy quarks?

Physical Review D, 1977
Flavor-changing neutral currents are reconsidered allowing the possibility that superheavy quarks, with masses comparable to the weak-boson mass, exist in nature. It is argued that the natural conservation of these weak neutral currents cannot be imposed to order ..cap alpha..G/sub F/ in this case.

Velocity distribution for quasistable acceleration in the presence of multiplicative noise

Physical Review E, 2013
Processes that are far both from equilibrium and from phase transition are studied. It is shown that a process with mean velocity that exhibits power-law growth in time can be analyzed using the Langevin equation with multiplicative noise. The solution to the corresponding Fokker-Planck equation is derived.

Bakamjian–Thomas construction for quasistable states

Journal of Physics A: Mathematical and Theoretical, 2008
As is evident from the multiple values listed in the particle data table for the mass and width of resonances, such as Z°, Δ and ρ, defining these resonance parameters uniquely and unambiguously remains an open problem. This problem is ultimately rooted in the absence of a state vector description of a resonance that has definite properties under ...

Quasistable states in globally coupled tent map systems

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2003
The characteristics of long lasting but not perpetual chaotic states appear in a wide parameter region in a globally coupled overcritical tent map system are exhibited. The lifetime of the transient state has essential relevance with the system size. In some parameter region, the lifetime saturates at a certain level, while in another region it seems ...

Ion-Enhanced Diffusion in Quasistable Drift Waves

The Physics of Fluids, 1972
An improved quasilinear theory of drift waves is shown to be capable of accounting for the existence of finite, ion-enhanced diffusion even when the waves are stable and collisions are absent.

Importance of a quasistable V4O9 to synthesize a highly crystalline VOHPO4·0.5H2O

Applied Catalysis A: General, 1995
Abstract The organic solvent method to synthesize a highly crystalline VOHPO4·0.5H2O was investigated. Firstly, reduction of V2O5 in alcohols was studied. It was clear that there existed a quasistable V4O9 state after reduction with isobutyl alcohol.

Quasistable state of an amplifying medium with an infinite energy store

Soviet Journal of Quantum Electronics, 1977
An analysis was made of the dynamics of population inversion and photon field density in an amplifying medium enclosed in a totally reflecting cavity and characterized by fast inversion switching. A dimensionless parameter D representing the stability of this medium is introduced.
