ω − N scattering length
We reanalyze the experimental data on ω–meson production in pion-nucleon collisions [1, 2, 3] based on both an analytical approach and a Monte Carlo simulation. Our analysis allows us to correct the data for the π − p→ωn reaction at energies close to threshold. The unusually strong energy dependence originally claimed for the near–threshold cross section is identified as a purely kinematical ef...
متن کاملLithiation and Substitution of N′-(ω-Phenylalkyl)-N,N-dimethylureas
Lithiation of N′-phenethyl-N,N-dimethylurea with three equivalents of tert-butyllithium in anhydrous tetrahydrofuran at –78 °C takes place on the nitrogen and on the side-chain of the CH2 next to the phenyl ring (α-lithiation). The 2-lithio isomer can be obtained via bromine–lithium exchange of N′-2-(2-bromophenyl)ethyl-N,N-dimethylurea using methyllithium followed by tertbutyllithium in tetrah...
متن کاملOn Total Ω-continuity, Strong Ω-continuity and Contra Ω-continuity by N. Rajesh
In this paper, ω-closed sets and ω-open sets are used to define and investigate a new class of functions. Relationships between this new class and other classes of functions are established.
متن کاملOn the nature of solutions of the difference equation $mathbf{x_{n+1}=x_{n}x_{n-3}-1}$
We investigate the long-term behavior of solutions of the difference equation[ x_{n+1}=x_{n}x_{n-3}-1 ,, n=0 ,, 1 ,, ldots ,, ]noindent where the initial conditions $x_{-3} ,, x_{-2} ,, x_{-1} ,, x_{0}$ are real numbers. In particular, we look at the periodicity and asymptotic periodicity of solutions, as well as the existence of unbounded solutions.
متن کاملThe reaction πN → ωN revisited : the ω − N scattering length
We reinvestigate the experimental data on ω–meson production in pion-nucleon collisions [1, 2, 3] based on both an analytical approach and a Monte Carlo simulation. Our analysis allows us to study the kinematical peculiarities of the π − p→ωn reaction at energies close to threshold. Based on the hypothesis, that the formalism derived in ref. [1] was applied improperly, the unusually strong ener...
